<title>Configuration</title>
<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>If you see an error message then you might need to install an
additional PHP extension. Please follow the instructions and reload the page
afterwards.</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 id="generalSettings">
<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>License (LAM Pro only)</title>
<para>This is only required when you run LAM Pro. Please enter the
license key from your <ulink
url="https://www.ldap-account-manager.org/lamcms/user/me">customer
profile</ulink>. In case you have purchased multiple licenses please
only enter one license key block per installation.</para>
<para>When you entered the license key then the license details can be
seen on LAM configuration overview page.</para>

<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/manual/en/book.openssl.php">OpenSSL</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>Password policy</title>
<para>This allows you to specify a central password policy for LAM. The
policy is valid for all password fields inside LAM admin (excluding tree
view) and LAM self service. Configuration passwords do not need to
follow this policy.</para>

<para>You can set the minimum password length and also the complexity of
the passwords.</para>
<para><emphasis role="bold">External password check</emphasis></para>
<para>Please note that this option is only displayed if you have
installed the PHP Curl extension for your web server.</para>
<para>This will validate passwords using an external service. LAM
supports the protocol used by <ulink
url="https://haveibeenpwned.com/API/v2#SearchingPwnedPasswordsByRange">Have
I been Pwned</ulink>. You can use the service directly or setup any
custom service with the same API. If the service reports an error LAM
will log an error message and the password will be accepted.</para>
<para>Example URL:
https://api.pwnedpasswords.com/range/{SHA1PREFIX}</para>
<para>LAM will build a SHA1 hash of the password and send parts of it to
the service.</para>
<para>The configured URL must contain the wildcard "{SHA1PREFIX}" which
will be replaced with the 5 character hash prefix. The service must then
return a list of text lines in the format "&lt;hash
suffix&gt;:&lt;number&gt;".</para>
<para>"&lt;hash suffix&gt;" needs to be the suffix of a known insecure
password. The "&lt;number&gt;" can be any numeric value and will be
ignored by LAM.</para>
<para>Example:</para>
<para>Password hash: 21BD10018A45C4D1DEF81644B54AB7F969B88D65</para>
<para>Hash prefix sent to service: 21BD1</para>
<para>Returned line: 0018A45C4D1DEF81644B54AB7F969B88D65:1</para>
<para>This will reject the password.</para>
</section>
<section id="conf_logging">
<title>Logging</title>
<para>LAM can log events (e.g. user logins). You can use e.g. 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 PHP error reporting is only for developers. By default LAM
does not show PHP notice messages in the web pages. You can select to
use the php.ini setting here or printing all errors and notices.</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

the different access levels.</para>
<para><emphasis role="bold">Advanced options</emphasis></para>
<para>Display name: Sometimes, you may not want to display the server
address on the login page. In this case you can setup a display name
here (e.g. "Production").</para>
<para>Follow referrals: By default LAM will not follow LDAP referrals.
This is ok for most installations. If you use LDAP referrals please
activate the referral option in advanced settings.</para>
<para>Paged results: 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>Referential integrity overlay: Activate this checkbox if you
have any server side extension for referential integrity in place. In
this case the server will cleanup references to LDAP entries that are
deleted.</para>

<para>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
url="http://www.openldap.org/doc/admin24/overlays.html">"memberOf"</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.
"(&amp;(uid=%USER%)(memberof=cn=admins,ou=groups,dc=company,dc=com))").</para>

the user will not only authenticate by user+password but also with
e.g. a token generated by a mobile device. This adds more security
because the token is generated on a physically separated device
(typically mobile phone).</para>

account modules. E.g. you may select "Personal" as base module and
Unix + Samba as additional modules.</para>

<para>LAM also prints the crontab line that you need to run the
configured jobs on a daily basis. The command must be run as the same
user as your webserver is running. You are free to change the starting
time of the script or run it more often.</para>
<para>Dry-run: You can perform a dry-run of the job. This will not
perform any actions but only print what would be done. For this please
put "--dryRun" at the end of the command. E.g.:</para>

be either specified as a fixed list or by using an LDAP search at
login time.</para>

<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>

<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>
<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 (&gt;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>
