Joe Little and I gave a talk last night SVLUG on LDAP directory services and the Open-IT project. Open-IT is, amongst other things, a clearinghouse for RPMs of PADL's Open Source offerings.
Over the weekend I wrote some glue between JavaLDAPand Ganymede. Ganymede is a very cool, object-oriented framework for managing directory information, and although it is not designed to be used as a directory service per se, it maps closely enough to LDAP that I thought it would be an interesting project to integrate the two.
Also, there are new releases of pam_ldap and nss_ldap. These should show up on Freshmeat soon.
