The Active Directory module is based on the <a href="authldap.html" class="wikilink1" title="documentation:2.0:authldap">LDAP module</a>, with these features:

<div class="level2">
|
|
|
|
<p>
|
|
AD password policy does not follow the LDAP <abbr title="Request for Comments">RFC</abbr>, but Microsoft has implemented its own policy.
|
|
LemonLDAP::NG implements partially the policy:
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> when pwdLastSet = 0 in the user entry, it means that password has been reset, and a form is presented to the user for him to change his password.</div>
|
|
</li>
|
|
<li class="level1"><div class="li"> when computed virtual attribute 'msDS-User-Account-Control-Computed' as 6th flag set to 8, the password is considered expired (support from Windows Server 2003). It is too late for the user to do anything. He must contact his administrator.</div>
|
|
</li>
|
|
<li class="level1"><div class="li"> a warning before password expiration is possible in AD, but only in GPO (Computer Configuration\Windows Settings\Local Policies\Security Options under Interactive Logon: Prompt user to change password before expiration). However it as no reality in LDAP referential. A "password warning time before password expiration" variable can be specified in LemonLDAP::NG to do so.</div>
|
|
</li>
|
|
</ul>
|
|
<div class="noteimportant">Note: since AD 2012, each user can have a specific password expiration policy. Then, the "maximum password age" can have different values. This is currently unsupported in LemonLDAP::NG because every policy must be computed with their precedence to know which maximum password age to apply.
|
|
</div>
|
|
<p>
|
|
To configure warning before password expiration, you must set two variables in Active Directory parameters in Manager:
|
|
</p>
|
|
<ul>
|
|
<li class="level1"><div class="li"> <strong>Password max age</strong> : number of seconds after the last password change, before it expires. It must match AD policy</div>
|
|
</li>
|
|
<li class="level1"><div class="li"> <strong>Password expire warning</strong> : number of seconds between password expiration and the date from which user is warned his password will expire.</div>
|
|
</li>
|
|
</ul>
