Plugin Name: Simple LDAP Login
Description: Integrating WordPress with LDAP shouldn’t be difficult. Now it isn’t. Simple LDAP Login provides all of the features, none of the hassles.
- Supports Active Directory and OpenLDAP (and other directory systems which comply to the LDAP standard, such as OpenDS)
- Supports TLS
- Uses up-to-date methods for WordPress authentication routines.
- Authenticates existing WordPress usernames against LDAP.
- Can be configured to automatically create WordPress users for valid LDAP logins.
- You can restrict logins based on one or more LDAP groups.
- Intuitive control panel.
Simple LDAP Login adds an authentication filter to WordPress that authentication requests must pass. In doing so, it makes several decisions.
- Can the provided credentials be authenticated against LDAP?
- If so, is the LDAP user a member of the required LDAP groups (if any)?
- Does a matching WordPress user exist?
- If so, log the user in.
- If not, is user creation enabled?
- Create the user and log them in.
This is high level overview. This should answer the philosophical questions about how the plugin works. If the plugin is unable to authenticate the user, it should pass it down the chain to WordPress. (Unless LDAP Exclusive is turned on, in which case it won’t.)
The comments below are the quickest way to get my attention for bug fixes. I do try to check the support forums occasionally, but my response times there are much slower.
