This plugin will enable WP authentication and role management from LDAP server. 
Users who log in to your WP site are authenticated by first matching the 
username input against an attribute to local the RDN. Then a bind is performed 
against the RDN. Upon successful bind, authentication is approved. Local WP 
user management is engaged by initializing and maintaining user DB records.
Simply create your users in your LDAP directly. Define access rights or “roles” 
to specific WP sites. When the user logs into the WP site, the local DB user 
entry is created.
Use LDAP to define users in one place for access to one or many WP sites.
User passwords in the local DB are replaced with jumbled text and are unusable. 
All password information is maintained in LDAP.
User information ( Display Name, Nick Name, Nice Name, First Name, Last Name ) 
are maintained in master form in LDAP and stored and updated (synced) to the 
local DB when the user logs in.

<h3>Architecture</h3>
Simple LDAP adds an authentication filter to WordPress that authentication requests must pass. 
Consults LDAP for current role configuration.

Plugin Name: ldap_login_password_and_role_manager

Enables LDAP for user authentication, password management and role management.

CoSign SSO is a WordPress plugin that provides several alternative authentication methods to WordPress, and it maybe easily extend to support more SSO login methods. CoSign v2 and CoSign v3 are the first two Single Sign-on(SSO) addins, that whay this plugin named. The other login method is just a by-product which provides LDAP authentication.
When this plugin is enabled, and the login method is set to SSO, then using a external CoSign single sign-on login service. When user click login, browser will redirect to remote login url, and will redirect back after successful logged in. If set login method to LDAP, login with the familiar login screen, but authentication backend changed to LDAP.
Whether using SSO or LDAP login method, LDAP options must provided to fetch user account information. If the logged in user account does not exists, create it on the fly by default.
<h3>Settings</h3>
The settings for CoSign SSO are extremely simple. But before you change the login method to ‘SSO’ or ‘LDAP’, you mast check options for cosign and ldap carefully. Wrong configrations will ban all users including yourself!
If you cannot login any more, don’t blame me. A trick may help you:
<pre><code>$ touch <PLUGIN_DIR>/cosign-sso/FALLBACK
</code></pre>
If the fallback file contains “ldap”, “cosign2”, or “cosign3”, it will fallback to the right login method.
After you correct the settings, not forgot to remove the FALLBACK file.
Notes for CoSign 3.x:
<ul>
<li>CoSign 3.x filter needs to add a “/cosign/valid” location as cosign handler.</li>
<li>If wordpress uses a permlink, which means the RewriteRule in .htaccess may conflict with the “/cosign/valid” handler.</li>
<li>You can hack wp-includes/rewrite.php, add “RewriteRule ^cosign/valid – [L]” right after “RewriteBase” directive.</li>
</ul>
<h3>Localization</h3>
This section describes how to localized, which means let cosign-sso speak in your language.
<ul>
<li>POT file : cosign-sso/languages/cosign_sso.pot</li>
<li>Copy pot file to your locale, such as cosign-sso/languages/cosign_sso-zh_CN.pot for Chinese.</li>
<li>Translate it using your favorate editor. lokalize and kbabel are recommended.</li>
<li>Convert po to mo using command: </li>
</ul>
<pre>
 $ cd plugins/cosign-sso/languages
 $ msgfmt cosign_sso-zh_CN.po -o cosign_sso-zh_CN.mo
