User pictures in LDAP

Has anyone actually got user pictures in their LDAP database? I kow about the official apple way: http://developer.apple.com/documentation/MacOSXServer/Conceptual/ XServer_ProgrammingGuide/Articles/UserImagesinOpenDirectory.html> But I would like to do it with base-64 pictures stored in the directoy in the jpegPhoto attribute from the inetOrgPerson schema rather than apple- picture. Anybody succesful?
