<h2>1. Loading the LDAP attributes<br>
|
|
</h2>
|
|
Every time the user selects an existing account to modify LAM will load
|
|
the complete LDAP entry of it. Your module then should select the
|
|
attributes which are useful for it.<br>
|
|
There are two variables in <span style="font-style: italic;">baseModule</span>
|
|
which should be used to store the attributes. The <span style="font-weight: bold;">$attributes</span> variable stores the
|
|
current attributes including changes the user made. The <span style="font-weight: bold;">$orig</span> variable stores the attributes
|
|
as they were originally when the account was loaded. This allows you to
|
|
see what changes were made.<br>
|
|
<br>
|
|
The <span style="font-weight: bold;">load_attributes()</span> function
|
|
in your module gets the complete attribute list from LDAP.<br>
|
|
<br>
|
|
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br style="font-weight: bold; text-decoration: underline;">
|
|
<br>
|
|
The <span style="font-style: italic;">ieee802Device</span> uses an
|
|
object class and the <span style="font-style: italic;">'macAddress'</span>
|
|
attribute. Therefore we will save this two values.<br>

|

<h2>2. Page display</h2>
|
|
Now that you have defined your subpages you will need one function for
|
|
each page to display it. The function must return <span style="font-style: italic;">meta HTML code</span> as defined in the <span style="font-style: italic;">modules specification</span>.<br>
|
|
This function is called <span style="font-weight: bold;">display_html_<page
|
|
name>()</span> where <span style="font-style: italic;"><page
|
|
name></span> is the name of your subpage.<br>

|
|
module has only one subpage called <span style="font-style: italic;">'attributes'</span>.<br>
|
|
<br>
|
|
The first half of the code displays the existing MAC addresses and the
|
|
second an input field for new values.<br>
|
|
The variable <span style="font-style: italic;">$this->attributes</span>
|
|
contains the LDAP attributes which are useful for this module.<br>

<h2>3. Processing input data<br>
|
|
</h2>
|
|
Every time the user clicks on a submit button while your page is
|
|
displayed LAM will call a function in your module.<br>
|
|
This function is called <span style="font-weight: bold;">process_<page
|
|
name>()</span> where <span style="font-style: italic;"><page
|
|
name></span> is the name of your subpage.<br>
|
|
<br>
|
|
If all input data is ok then return an empty array. If you return one or more error messages then the user will be
|
|
redirected to your page.<br>
|
|
<br>
|
|
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br style="font-weight: bold; text-decoration: underline;">
|
|
<br>
|
|
The
|
|
<span style="font-style: italic;">ieee802Device</span>
|
|
module has only one subpage called <span style="font-style: italic;">'attributes'</span>
|
|
and therefore only <span style="font-style: italic;">process_attributes()</span>.<br>
|
|
<br>
|
|
The function checks the input fields and fills the LDAP attributes. If
|
|
all is ok it will enable the user to move to another module page.<br>

<h2>4. Defining that your module is ready for user input and LDAP
|
|
add/modify</h2>
|
|
In most cases you will not need to implement these functions. The <span style="font-style: italic;">baseModule</span> will return <span style="font-style: italic;">true</span> for both functions.<br>
|
|
<br>
|
|
<span style="text-decoration: underline;"><br>
|
|
There are two functions which control the module status:</span><br style="text-decoration: underline;">
|
|
<br>
|
|
The <span style="font-weight: bold;">module_ready()</span> function
|
|
has to
|
|
return <span style="font-style: italic;">true</span> if the user may
|
|
move to your module page. If it is <span style="font-style: italic;">false</span>
|
|
the user will be shown an error message that your module is not yet
|
|
ready. You can use this if your module depends on input data from other
|
|
modules (e.g. you need the user name from posixAccount first).<br>
|
|
<br>
|
|
The second function is
|
|
<span style="font-weight: bold;">module_complete()</span>. The user
|
|
cannot do the LDAP operation if one or more modules return <span style="font-style: italic;">false</span>. This defines if all needed
|
|
input data for your module was entered.<br>
|
|
Use this function if you want to check that all required attributes are
|
|
set.<br>
|
|
<br>
|
|
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br style="font-weight: bold; text-decoration: underline;">
|
|
<br>
|
|
The <span style="font-style: italic;">sambaSamAccount</span>
|
|
module needs the user's <span style="font-style: italic;">uidNumber</span>
|
|
and <span style="font-style: italic;">gidNumber</span> before it can
|
|
accept input and the account needs a <span style="font-style: italic;">sambaSID</span>
|
|
before it can be saved.<br>

<br>
|

<h2>5. Saving the LDAP attributes<br>
|
|
</h2>
|
|
In most cases you will not have to implement this option if you use <span style="font-weight: bold;">$this->attributes</span> and <span style="font-weight: bold;">$this->orig</span> to manage the LDAP
|
|
attributes. The <span style="font-style: italic;">baseModule</span>
|
|
will generate the save comands for you.<br>
|
|
<br>
|
|
When all modules report that they are ready for LDAP add/modify and the
|
|
user clicks on the add/modify button your module will be asked what
|
|
changes have to be made.<br>
|
|
This is done in the function <span style="font-weight: bold;">save_attributes()</span>.<br>
|
|
<br>
|
|
<span style="font-weight: bold; text-decoration: underline;">Example:</span><br style="font-weight: bold; text-decoration: underline;">
|
|
<br>
|
|
The <span style="font-style: italic;">kolabUser</span> module uses
|
|
this function to make sure that its object class is saved. Other
|
|
modules (e.g. quota) use it build the lamdaemon commands.<br>
