<title>LDAP Account Manager - Manual</title>
<preface>
<title>Overview</title>
<para>LDAP Account Manager (LAM) manages user, group and host accounts in
an LDAP directory. LAM runs on any webserver with PHP5 support and
connects to your LDAP server unencrypted or via SSL/TLS.</para>
<para>LAM supports Samba 3, Unix, Zarafa, Kolab 2/3, address book entries,
NIS mail aliases, MAC addresses and much more. There is a tree viewer
included to allow access to the raw LDAP attributes. You can use templates
for account creation and use multiple configuration profiles.</para>

<title>Architecture</title>
<para>There are basically two groups of users for LAM:</para>
<itemizedlist>
<listitem>
<para><emphasis role="bold">LDAP administrators and support
staff:</emphasis></para>
<para>These people administer LDAP entries like user accounts, groups,
...</para>
</listitem>
<listitem>
<para><emphasis role="bold">Users:</emphasis></para>
<para>This includes all people who need to manage their own data
inside the LDAP directory. E.g. these people edit their contact
information with LAM self service (LAM Pro).</para>
</listitem>
</itemizedlist>
<screenshot>
<mediaobject>
<imageobject>
<imagedata fileref="images/lam_architecture.png" />
</imageobject>
</mediaobject>
</screenshot>
<para>Therefore, LAM is split into two separate parts, LAM for admins and
for users. LAM for admins allows to manage various types of LDAP entries
(e.g. users, groups, hosts, ...). It also contains tools like batch
upload, account profiles, LDAP schema viewer and an LDAP browser. LAM for
users focuses on end users. It provides a self service for the users to
edit their personal data (e.g. contact information). The LAM administrator
is able to specify what data may be changed by the users. The design is
also adaptable to your corporate design.</para>
<para>LAM for admins/users is accessible via HTTP(S) by all major web
browsers (Firefox, IE, Opera, ...).</para>
<para><emphasis role="bold">LAM runtime environment:</emphasis></para>
<para>LAM runs on PHP. Therefore, it is independant of CPU architecture
and operating system (OS). You can run LAM on any OS which supports
Apache, Nginx or other PHP compatible web servers.</para>
<para><emphasis role="bold">Home directory server:</emphasis></para>
<para>You can manage user home directories and their quotas inside LAM.
The home directories may reside on the server where LAM is installed or
any remote server. The commands for home directory management are secured
by SSH. LAM will use the user name and password of the logged in LAM
administrator for authentication.</para>
<para><emphasis role="bold">LDAP directory:</emphasis></para>
<para>LAM connects to your LDAP server via standard LDAP protocol. It also
supports encrypted connections with SSL and TLS.</para>

<para>After you <link linkend="a_installation">installed</link> LAM you
can configure it to fit your needs. The complete configuration can be done
inside the application. There is no need to edit configuration
files.</para>
<para>Please point you browser to the location where you installed LAM.
E.g. for Debian/RPM this is http://yourServer/lam. If you installed LAM
via the tar.bz2 then this may vary. You should see the following
page:</para>

<para>Here you can change LAM's general settings, setup server profiles
for your LDAP server(s) and configure the <link
linkend="a_selfService">self service</link> (LAM Pro). You should start
with the general settings and then setup a server profile.</para>
<section>
<title>General settings</title>
<para>After selecting "Edit general settings" you will need to enter the
<link linkend="a_configPasswords">master configuration password</link>.
The default password for new installations is "lam". Now you can edit
the general settings.</para>
<section>
<title>Security settings</title>
<para>Here you can set a time period after which inactive sessions are
automatically invalidated. The selected value represents minutes of
inactivity.</para>
<para>You may also set a list of IP addresses which are allowed to
access LAM. The IPs can be specified as full IP (e.g. 123.123.123.123)
or with the "*" wildcard (e.g. 123.123.123.*). Users which try to
access LAM via an untrusted IP only get blank pages. There is a
separate field for LAM Pro self service.</para>
<para id="sessionEncryption">Session encryption will encrypt sensitive
data like passwords in your session files. This is only available when
PHP <ulink url="http://php.net/mcrypt">MCrypt</ulink> is active. This
adds extra security but also costs performance. If you manage a large
directory you might want to disable this and take other actions to
secure your LAM server.</para>

<para id="conf_sslCert"><emphasis role="bold">SSL certificate
setup:</emphasis></para>
<para>By default, LAM uses the CA certificates that are preinstalled
on your system. This will work if you connect via SSL/TLS to an LDAP
server that uses a certificate signed by a well-known CA. In case you
use your own CA (e.g. company internal CA) you can import the CA
certificates here.</para>
<para>Please note that this can affect other web applications on the
same server if they require different certificates. There seem to be
problems on Debian systems and you may also need to restart Apache. In
case of any problems please delete the uploaded certificates and use
the <link linkend="ssl_certSystem">system setup</link>.</para>
<para>You can either upload a DER/PEM formatted certificate file or
import the certificates directly from an LDAP server that is available
with LDAP+SSL (ldaps://). LAM will automatically override system
certificates if at least one certificate is uploaded/imported.</para>
<para>The whole certificate list can be downloaded in PEM format. You
can also delete single certificates from the list.</para>
<para>Please note that you might need to restart your webserver if you
do any changes to this configuration.</para>

<title>Logging</title>
<para>LAM can log events (e.g. user logins). You can use system
logging (syslog for Unix, event viewer for Windows) or log to a
separate file. Please note that LAM may log sensitive data (e.g.
passwords) at log level "Debug". Production systems should be set to
"Warning" or "Error".</para>

<para>The server address of your LDAP server can be a DNS name or an
IP address. Use ldap:// for unencrypted LDAP connections or TLS
encrypted connections. LDAP+SSL (LDAPS) encrypted connections are
specified with ldaps://. The port value is optional. TLS cannot be
combined with ldaps://.</para>
<para>Hint: If you use a master/slave setup with referrals then
point LAM to your master server. Due to bugs in the underlying LDAP
libraries pointing to a slave might cause issues on write
operations.</para>
<para>LAM includes an LDAP browser which allows direct modification
of LDAP entries. If you would like to use it then enter the LDAP
suffix at "Tree suffix".</para>
<para>The search limit is used to reduce the number of search
results which are returned by your LDAP server.</para>
<para>The access level specifies if LAM should allow to modify LDAP
entries. This feature is only available in LAM Pro. LAM non-Pro
releases use write access. See <link

<para>By default LAM will not follow LDAP referrals. This is ok for
most installations. If you use LDAP referrals please activate the

<para>Paged results should be activated only if you encounter any
problems regarding size limits on Active Directory. LAM will then
query LDAP to return results in chunks of 999 entries.</para>

<para>LAM supports two methods for login. The first one is to
specify a fixed list of LDAP DNs that are allowed to login. Please
enter one DN per line.</para>
<para>The second one is to let LAM search for the DN in your
directory. E.g. if a user logs in with the user name "joe" then LAM
will do an LDAP search for this user name. When it finds a matching
DN then it will use this to authenticate the user. The wildcard
"%USER%" will be replaced by "joe" in this example. This way you can
provide login by user name, email address or other LDAP
attributes.</para>
<para>Additionally, you can enable HTTP authentication when using
"LDAP search". This way the web server is responsible to
authenticate your users. LAM will use the given user name + password
for the LDAP login. You can also configure this to setup advanced
login restrictions (e.g. require group memberships for login). To
setup HTTP authentication in Apache please see this <ulink
url="http://httpd.apache.org/docs/2.2/howto/auth.html">link</ulink>
and an example for LDAP authentication <link lang=""
linkend="apache_http_auth">here</link>.</para>
<para><emphasis role="bold">Hint:</emphasis> LDAP search with group
membership check can be done with either <link
linkend="apache_http_auth">HTTP authentication</link> or LDAP
overlays like <ulink

or <ulink
url="http://www.openldap.org/doc/admin24/overlays.html">"Dynamic
lists"</ulink>. Dynamic lists allow to insert virtual attributes to
your user entries. These can then be used for the LDAP filter (e.g.
"(&(uid=%USER%)(memberof=cn=admins,ou=groups,dc=company,dc=com))").</para>

<para><emphasis role="bold">Additional LDAP filter:</emphasis>
LAM will automatically detect the right LDAP entries for each
account type. This can be used to further limit the number of
visible entries (e.g. if you want to manage only some specific
groups). You can use "@@LOGIN_DN@@" as wildcard (e.g.
"(owner=@@LOGIN_DN@@)"). It will be replaced by the DN of the
user who is logged in.</para>
</listitem>
<listitem>
<para><emphasis role="bold">Hidden:</emphasis> This is used to
hide account types that should not be displayed but are required
by other account types. E.g. you can hide the Samba domains
account type and still assign domains when you edit your
users.</para>
</listitem>
<listitem>
<para><emphasis role="bold">Read-only (LAM Pro only):</emphasis>
This allows to set a single account type to read-only mode.
Please note that this is a restriction on functional level (e.g.
group memberships can be changed on user page even if groups are
read-only) and is no replacement for setting up proper ACLs on
your LDAP server.</para>

<para>Each account type needs a so called "base module". This is the
basement for all LDAP entries of this type. Usually, it provides the
structural object class for the LDAP entries. There must be exactly
one active base module for each account type.</para>
<para>Furthermore, there may be any number of additional active
account modules. E.g. you may select "Personal" as base module and
Unix + Samba as additional modules.</para>
</section>
<section>
<title>Module settings</title>
<para>Depending on the activated account modules there may be
additional configuration options available. They can be found on the
"Module settings" tab. E.g. the Personal account module allows to
hide several input fields and the Unix module requires to specify
ranges for UID numbers.</para>

<title>Typical scenarios</title>
<para>This is a list of typical scenarios how your LDAP environment
may look like and how to structure the server profiles for it.</para>
<section>
<title>Simple: One LDAP directory managed by a small group of
admins</title>
<para>This is the easiest and most common scenario. You want to
manage a single LDAP server and there is only one or a few admins.
In this case just create one server profile and you are done. The
admins may be either specified as a fixed list or by using an LDAP
search at login time.</para>

</section>
<section>
<title>Advanced: One LDAP server which is managed by different admin
groups</title>
<para>Large organisations may have one big LDAP directory for all
user/group accounts. But the users are managed by different groups
of admins (e.g. departments, locations, subsidiaries, ...). The
users are typically divided into organisational units in the LDAP
tree. Admins may only manage the users in their part of the
tree.</para>
<screenshot>
<mediaobject>
<imageobject>
<imagedata fileref="images/LDAPStructuresAdvanced.png" />
</imageobject>
</mediaobject>
</screenshot>
<para>In this situation it is recommended to create one server
profile for each admin group (e.g. department). Setup the LDAP
suffixes in the server profiles to point to the needed
organisational units. E.g. use
ou=people,ou=department1,dc=company,dc=com or
ou=department1,ou=people,dc=company,dc=com as LDAP suffix for users.
Do the same for groups, hosts, ... This way each admin group will
only see its own users. You may want to use LDAP search for the LAM
login in this scenario. This will prevent that you need to update a
server profile if the number of admins changes.</para>
<para><emphasis role="bold">Attention:</emphasis> LAM's feature to
automatically find free UIDs/GIDs for new users/groups will not work
in this case. LAM uses the user/group suffix to search for already
assigned UIDs/GIDs. As an alternative you can specify different
UID/GID ranges for each department. Then the UIDs/GIDs will stay
unique for the whole directory.</para>
</section>
<section>
<title>Multiple LDAP servers</title>
<para>You can manage as many LDAP servers with LAM as you wish. This
scenario is similar to the advanced scenario above. Just create one
server profile for each LDAP server.</para>

<title>Single LDAP directory with lots of users (>10 000)</title>
<para>LAM was tested to work with 10 000 users. If you have a lot
more users then you have basically two options.</para>
<itemizedlist>
<listitem>
<para>Divide your LDAP tree in organisational units: This is
usually the best performing option. Put your accounts in several
organisational units and setup LAM as in the advanced scenario
above.</para>
</listitem>
<listitem>
<para>Increase memory limit: Increase the memory_limit parameter
in your php.ini. This will allow LAM to read more entries. But
this will slow down the response times of LAM.</para>

<title>Managing entries in your LDAP directory</title>
<para>This chapter will give you instructions how to manage the different

<para>Please note that not all account types are manageable with the free
LAM release. LAM Pro provides some more account types (e.g. group of
names, aliases, ...) and modules (e.g. Zarafa, custom scripts, ...) to
support additional LDAP object classes. All LAM Pro features are marked in
this manual.</para>
<para><emphasis role="bold">Basic page layout:</emphasis></para>
<para>After the login LAM will present you its main page. It consists of a
header part which is equal for all pages and the content area which covers
most the of the page.</para>
<para>The header part includes the links to manage all account types (e.g.
users and groups) and open the tree view (LDAP browser). There is also the

<title>IMAP mailboxes</title>
<para>LAM may create and delete mailboxes on an IMAP server for your
user accounts. You will need an IMAP server that supports either SSL
or TLS for this feature.</para>
<para>To activate the mailbox management module please add the
"Mailbox (imapAccess)" module for the type user in your LAM server
profile:</para>
<screenshot>
<mediaobject>
<imageobject>
<imagedata fileref="images/imapAccess1.png" />
</imageobject>
</mediaobject>
</screenshot>
<para>Now configure the module on the tab "Module settings". Here you
can specify the IMAP server name, encryption options, the
authentication for the IMAP connection and the valid mail domains. LAM
can use either your LAM login password for the IMAP connection or
display a dialog where you need to enter the password. It is also
possible to store the admin password in your server profile. This is
not recommended for security reasons.</para>
<para>The user name can either be a fixed name (e.g. "admin") or it
can be generated with LDAP attributes of the LAM admn user. E.g. $uid$
will be transformed to "myUser" if you login with
"uid=myUser,ou=people,dc=example,dc=com".</para>
<para>The mail domains specify for which accounts mailboxes may be
created/deleted. E.g. if you enter "lam-demo.org" then mailboxes can
be managed for "user@lam-demo.org" but not for "user@example.com". Use
"*" for any domain.</para>
<para>You need to install the SSL certificate of the CA that signed
your server certificate. This is usually done by installing the
certificate in /etc/ssl/certs. Different Linux distributions may offer
different ways to do this. For Debian please copy the certificate in
"/usr/local/share/ca-certificates" and run "update-ca-certificates" as
root.</para>
<para>It is not recommended to disable the validation of IMAP server
certificates.</para>
<para>The prefix, user name attribute and path separator specifies how
your mailboxes are named (e.g. "user.myUser@localhost" or
"user/myUser"). Select the values depending on your IMAP server
settings.</para>

independently.</para>
<para>To create a group please edit your server profile and switch to
tab "Module settings". You will see the section "Custom fields" which

file upload to create them. LAM will read a CSV formatted file and
create the related LDAP entries. Please check the data in you CSV file
carefully. LAM will do less checks for the file upload than for single

CSV file. All red options are required columns in the file. You need to
specify a value for each account.</para>
<para>When you upload the CSV file then LAM first does some checks on
this file. This includes syntax checks and if all required data was
entered. No changes in the LDAP directory are done at this time.</para>
<para>If the checks were successful then LAM will ask again if you want
to create the accounts. You will also have the chance to check the

<para>This tool allows you to modify a large list of LDAP entries in
batch mode. You can add new attributes/object classes, remove attributes
and set attributes to a specific value.</para>
<para>At the beginning, you need to specify where the entries are stored
that should be changed. You can select an account suffix, the tree
suffix or enter your own DN by selecting "Other".</para>
<para>Next, enter an additional LDAP filter to limit the entries that
should be changed. E.g. use "(objectclass=inetOrgPerson)" to filter for
users. You may also enter e.g. "(!(objectClass=passwordSelfReset))" to
match all accounts that do not yet have the <link
linkend="passwordSelfResetUser">password self reset</link>
feature.</para>

<para>You can now configure the minimum answer length for password
reset answers. This is checked when you allow you users to specify
their answers via the self service. Additionally, you can specify the
text of the password reset link (default: "Forgot password?"). The
link is displayed below the password field on the self service login
page.</para>
<para>Next, please enter the DN and password of an LDAP entry that is
allowed to reset the passwords. This entry needs write access to the
attributes shadowLastChange, pwdAccountLockedTime and userPassword. It
also needs read access to uid, mail, passwordSelfResetQuestion and
passwordSelfResetAnswer. Please note that LAM Pro saves the password
on your server file system. Therefore, it is required to protect your
server against unauthorised access.</para>
<para>Please also specify the list of password reset questions that
the user can choose.</para>
<para>Please note that self service and LAM admin interface are
separated functionalities. You need to specify the list of possible
security questions in both self service profile(s) and server
profile(s).</para>
<literallayout> </literallayout>
<para>You can inform your users via mail about their password change.
The mail can include the new password by using the special wildcard
"@@newPassword@@". Additionally, you may want to insert other
wildcards that are replaced by the corresponding LDAP attributes. E.g.
"@@uid@@" will be replaced by the user name. Please see <link
linkend="mailEOL">email format option</link> in case of broken mails.
See <link linkend="mailSetup">here</link> for setting up your SMTP
server.</para>
<literallayout> </literallayout>
<para>LAM Pro can send your users an email with a confirmation link to
validate their email address. Of course, this should only be used if
the email account is independent from the user password (e.g. at
external provider) or you use the backup email address feature. The
mail body must include the confirmation link by using the special
wildcard "@@resetLink@@". Additionally, you may want to insert other
wildcards that are replaced by the corresponding LDAP attributes. E.g.
"@@uid@@" will be replaced by the user name.</para>
<para>There is also an option to skip the security question at all if
email verification is enabled. In this case the password can be reset
directly after clicking on the confirmation link. Please handle with
care since anybody with access to the user's mail account can reset
the password.</para>

intranet pages (e.g. colors and fonts). To include additional CSS
files just use the following setting for this task. The additional CSS
links will be added after LAM Pro's default CSS link. This way you can
overwrite LAM Pro's style.</para>

<section id="a_configPasswords">
<title>LAM configuration passwords</title>
<para>LAM supports a two level authorization system for its
configuration. Therefore, there are two types of configuration
passwords:</para>
<itemizedlist>
<listitem>
<para><emphasis role="bold">master configuration
password:</emphasis> needed to change general settings,
create/delete server profiles and self service profiles</para>
</listitem>
<listitem>
<para><emphasis role="bold">server profile password:</emphasis> used
to change the settings of a server profile (e.g. LDAP server and
account types to manage)</para>
</listitem>
</itemizedlist>
<para>The master configuration password can be used to reset a server
profile password. Each server profile has its own profile
password.</para>
<para>Both password types are stored as hash values in the configuration
files for enhanced security.</para>
</section>
<section>
<title>Use of SSL</title>
<para>The data which is transfered between you and LAM is very
sensitive. Please always use SSL encrypted connections between LAM and
your browser to protect yourself against network sniffers.</para>
</section>
<section>
<title>LDAP with SSL and TLS</title>
<para>SSL will be used if you use ldaps://servername in your
configuration profile. TLS can be activated with the "Activate TLS"
option.</para>
<para>If your LDAP server uses a SSL certificate of a well-know
certificate authority (CA) then you probably need no changes. If you use
a custom CA in your company then there are two ways to setup the CA
certificates.</para>
<section>
<title>Setup SSL certificates in LAM general settings</title>
<para>This is much easier than system level setup and will only affect
LAM. There might be some cases where other web applications on the
same web server are influenced.</para>
<para>See <link linkend="conf_sslCert">here</link> for details.</para>
</section>
<section id="ssl_certSystem">
<title>Setup SSL certificates on system level</title>
<para>This will make the CA certificates available also to other
applications on your system (e.g. other web applications).</para>
<para>You will need to setup ldap.conf to trust your server
certificate. Some installations use /etc/ldap.conf and some use
/etc/ldap/ldap.conf. It is a good idea to symlink /etc/ldap.conf to
/etc/ldap/ldap.conf. Specify the server CA certificate with the
following option:</para>
<programlisting>TLS_CACERT /etc/ldap/ca/myCA/cacert.pem</programlisting>
<para>This needs to be the public part of the signing certificate
authority. See "man ldap.conf" for additional options.</para>
<literallayout>
</literallayout>
<para>You may also need to specify the CA certificate in your Apache
configuration by using the option "LDAPTrustedGlobalCert":</para>
<programlisting>LDAPTrustedGlobalCert CA_BASE64 /etc/ldap/ca/myCA/cacert.pem</programlisting>
</section>
</section>
<section>
<title>Chrooted servers</title>
<para>If your server is chrooted and you have no access to /dev/random
or /dev/urandom this can be a security risk. LAM stores your LDAP
password encrypted in the session. LAM uses rand() to generate the key
if /dev/random and /dev/urandom are not accessible. Therefore the key
can be easily guessed. An attaker needs read access to the session file
(e.g. by another Apache instance) to exploit this.</para>
</section>
<section>
<title>Protection of your LDAP password and directory contents</title>
<para>You have to install the MCrypt extension for PHP to enable
encryption.</para>
<para>Your LDAP password is stored encrypted in the session file. The
key and IV to decrypt it are stored in two cookies. We use MCrypt/AES to
encrypt the password. All data that was read from LDAP and needs to be
stored in the session file is also encrypted.</para>
</section>
<section id="apache">
<title>Apache configuration</title>
<section>
<title>Sensitive directories</title>
<para>LAM includes several .htaccess files to protect your
configuration files and temporary data. Apache is often configured to
not use .htaccess files by default. Therefore, please check your
Apache configuration and change the override setting to:</para>
<para>AllowOverride All</para>
<para>If you are experienced in configuring Apache then you can also
copy the security settings from the .htaccess files to your main
Apache configuration.</para>
<para>If possible, you should not rely on .htaccess files but also
move the config and sess directory to a place outside of your WWW
root. You can put a symbolic link in the LAM directory so that LAM
finds the configuration/session files.</para>

<section id="apache_http_auth">
<title>Use LDAP HTTP authentication for LAM</title>
<para>With HTTP authentication Apache will be responsible to ask for
the user name and password. Both will then be forwarded to LAM which
will use it to access LDAP. This approach gives you more flexibility
to restrict the number of users that may access LAM (e.g. by requiring
group memberships).</para>
<para>First of all you need to load additional Apache modules. These
are "<ulink

and "<ulink type=""
url="http://httpd.apache.org/docs/2.2/mod/mod_authnz_ldap.html">mod_authnz_ldap</ulink>".</para>
<para>Next you can add a file called "lam_auth_ldap" to
/etc/apache/conf.d. This simple example restricts access to all URLs
beginning with "lam" to LDAP authentication.</para>
<programlisting><location /lam>
AuthType Basic
AuthBasicProvider ldap
AuthName "LAM"
AuthLDAPURL "ldap://localhost:389/ou=People,dc=company,dc=com?uid"

<para>You can also require that your users belong to a certain Unix
group in LDAP:</para>
<programlisting><location /lam>

<para><emphasis id="size_limit_exceeded" role="bold">Size
limit:</emphasis></para>
<para>You will get a message like "LDAP sizelimit exceeded, not all
entries are shown." when you hit the LDAP search limit.</para>
<para>OpenLDAP allows by default 500 return values per search, if you have
more users/groups/hosts please change this:</para>
<para>slapd.conf:</para>
<para>e.g. "sizelimit 10000" or "sizelimit -1" for unlimited return
values</para>
<para>slapd.d:</para>
<para>e.g. "olcSizeLimit: 10000" or "olcSizeLimit: -1" for unlimited
return values in /etc/ldap/slapd.d/cn=config.ldif</para>
<literallayout>
</literallayout>
<para><emphasis id="a_openldap_unique" role="bold">Unique
attributes:</emphasis></para>
<para>There are cases where you do not want that same attribute values
exist multiple times in your database. A good example are UID/GID
numbers.</para>
<para>OpenLDAP provides the <ulink
url="http://www.openldap.org/doc/admin24/overlays.html">attribute
uniqueness overlay</ulink> for this task.</para>
<para>Example to force unique UID numbers:</para>
<para>In
<emphasis>/etc/ldap/slapd.d/cn=config/cn=module{0}.ldif</emphasis> add
"olcModuleLoad: {3}unique" (replace "3" with the highest existing number
plus one).</para>
<para>Now in /etc/ldap/slapd.d/cn=config/olcDatabase={1}bdb.ldif add e.g.
"olcUniqueURI: ldap:///?uidNumber?sub"</para>
<literallayout>
</literallayout>
<para id="indices"><emphasis role="bold">Indices:</emphasis></para>
<para>Indices will improve the performance when searching for entries in
the LDAP directory. The following indices are recommended:</para>
<simplelist>
<member>index objectClass eq</member>
<member>index default sub</member>
<member>index uidNumber eq</member>
<member>index gidNumber eq</member>
<member>index memberUid eq</member>
<member>index cn,sn,uid,displayName pres,sub,eq</member>
<member># Samba 3.x</member>
<member>index sambaSID eq</member>
<member>index sambaPrimaryGroupSID eq</member>
<member>index sambaDomainName eq</member>
</simplelist>

<appendix id="mailSetup">
<title>Setup of email (SMTP) server</title>
<para>LAM always uses a local SMTP email server on the machine where LAM
is installed. Therefore, there is no need to configure any SMTP settings
inside LAM itself.</para>
<para>The local email server should be configured to forward all emails to
your company mail server (so-called smarthost). You can use any SMTP
software that ships with a Sendmail wrapper (e.g. Exim, Postfix, QMail or
Sendmail itself).</para>

<title>Adapt LAM to your corporate design</title>
<para>There are cases where you might want to change LAM's default
look'n'feel to better integrate it in your company network. Changes can be
done like this:</para>
<para><emphasis role="bold">Change colors, fonts and other parts with
custom CSS</emphasis></para>
<para>You can integrate custom CSS files in LAM. It is recommended to
write a separate CSS file instead of modifying LAM's default files.</para>
<para>The CSS files are located in</para>
<literallayout> DEB/RPM: /usr/share/ldap-account-manager/style
tar.bz2: style
</literallayout>
<para>LAM will automatically integrate all CSS files in alphabetical
order. E.g. you can create a file called "900_myCompany.css" which will be
added as last file.</para>
<para>Example:</para>
<para>This will change the background color of all pages to turquoise. See
500_layout.css for LAM's default settings.</para>
<programlisting>body {
background-color: #b6eeff;
}
</programlisting>
<para>You can use the same way to change fonts, sizes and more.</para>
<para>E.g. this will reduce the default font size to 80%:</para>
<programlisting>body {
font-size: 80%;
}
.ui-button-text-only {
font-size: 100%;
}
.ui-button-text-icon-primary {

<para><emphasis role="bold">Special changes with custom
JavaScript</emphasis></para>
<para>In rare cases it might not be sufficient to write custom CSS or
replace some image files. E.g. you might want to add custom content to all

<para>For these cases you can add a custom JavaScript file that contains
your code.</para>
<para>The JavaScript files are located in</para>
<literallayout> DEB/RPM: /usr/share/ldap-account-manager/templates/lib

<title>Clustering LAM</title>
<para>LAM is a web application based on PHP. Therefore, clustering is not
directly a part of the application.</para>
<para>But here are some hints to run LAM in a clustered
environment.</para>
<para><emphasis role="bold">Application parts:</emphasis></para>
<para>LAM can be divided into three parts</para>

<listitem>
<para>Session files and temporary data</para>
</listitem>
</itemizedlist>
<para><emphasis role="bold">Software:</emphasis></para>
<para>This is the simplest part. Just install LAM on each cluster node.
Please note that if you run LAM Pro you will need either one license for
each active cluster node or a company license.</para>
<para><emphasis role="bold">Configuration files:</emphasis></para>
<para>These files include the LAM server profiles, account profiles, PDF
structures, ... Usually, they do not change frequently and can be put on a
shared file system (e.g. NFS, AFS, ...).</para>
<para>Please link "config" or "/var/lib/ldap-account-manager/config" to a
directory on your shared file system.</para>
<para><emphasis role="bold">Session data and temporary
files:</emphasis></para>
<para>These are critical because the files may change on every page load.
There are basically two options:</para>
<itemizedlist>
<listitem>
<para>load balancer with session stickiness: In this case your load
balancer will forward all requests of a user to the same cluster node.
In this case you can keep the files locally on your cluster nodes. If
you already have a load balancer then this is the simplest solution
and performs best. The disadvantage is that if a node fails then all
users connected to this node will loose their session and need to
relogin.</para>
</listitem>
<listitem>
<para>shared file system: This should only be used if your load
balancer does not support session stickiness or you use a different
system to distribute request across the cluster. A shared file system
will decrease performance for all page loads.</para>
</listitem>
</itemizedlist>
<para>Session data and temporary files are located in "tmp" + "sess" or
"/var/lib/ldap-account-manager/tmp" +
"/var/lib/ldap-account-manager/sess".</para>

<title>Performance issues</title>
<para>LAM is tested to work with 10000 users with acceptable
performance. If you have a larger directory or slow hardware then here
are some points to increase performance.</para>
<literallayout>
</literallayout>
<para>The first step is to check if performance problems are caused by
the LAM web server or the LDAP server. Please check which machine
suffers from high system load (CPU/memory consumption).</para>
<para>High network latency may also be a problem. For large
installations please make sure that LAM web server and LDAP server are
located in the same building/server room.</para>
<para>If you run LAM on multiple nodes (DNS load balancing/hardware load
balancer) then also check the <link linkend="clustering">clustering
section</link>.</para>
<section>
<title>LDAP server</title>
<para><emphasis role="bold">Use indices</emphasis></para>
<para>Depending on the queries it may help to add some more indices on
the LDAP server. Depending on your LDAP software it may already
suggest indices in its log files. See <link
linkend="indices">here</link> for typical OpenLDAP indices.</para>
<literallayout>
</literallayout>
<para><emphasis role="bold">Reduce query results by splitting LDAP
management into multiple server profiles</emphasis></para>
<para>If you manage a very large directory then it might already be
separated into multiple subtrees (e.g. by country, subsidiary, ...).
Do not use a single LAM server profile to manage your whole directory.
Use different server profiles for each separated LDAP subtree where
possible (e.g. one for German users and one for French ones).</para>
<literallayout>
</literallayout>
<para><emphasis role="bold">Limit query results</emphasis></para>
<para>LAM allows to set an <ulink url="general_settings">LDAP search
limit</ulink> for each server profile. This will limit the number of
entries returned by your LDAP server. Use with caution because it can
cause problems (e.g. with automatic UID generation) when LAM is not
able to read all entries.</para>

<ulink url="http://www.zend.com/en/products/server/">Zend
Server</ulink> (commercial) that provide caching of PHP pages to
improve performance. They will reduce the time for parsing the PHP
pages and IO load.</para>
<para>This is a simply way to enhance performance since APC is part of
most Linux distributions.</para>
<para>If you use APC then make sure that it uses enough memory (e.g.
