I know there are some that have been waiting for this (Kimmo). I finally have found some time to get it done. You can now authenticate your user database via Active Directory or LDAP. There are a few changes needed to the core (until the next revision - see readme). I have tested it at my work with Active Directory and it is working just fine. I tried to design it so that other auth methods could be added easily. If anyone wants to submit code, please let me know.
