I just released bhLDAPAuthPlugin to the world with permission from my employer.  I’ve been using symfony (“PHP on Rails”) for about a year at work for a few intranet projects, and over and over I have needed to use our enterprise-wide Microsoft Active Directory® for user authentication and authorization. The plugin might work with non-Microsoft LDAP servers too, but I don’t have any of them to play with.

Maybe this will help other developers cook up Intranet apps that rock using symfony.

I have been able to rapidly develop some things that users really like with symfony, so I appreciate this chance to give back to the project.  Also, I’m the only one in my organization doing this sort of thing, so I hope I’ll be able to get some good feedback and contributions from others.
