I haven't had any problems with OpenLDAP in the past. We're not using it right now, but I'll likely be doing something with it in the near future. To effectively manage the OpenLDAP server for simple user logins and system accounts, look at the commandline tool called "cpu". Yes, bad name. Simple and effective. There are some nice GUI and WebUI tools out there as well. Remember, with LDAP, you can stuff a lot of information into it, and most of your essential network services applications have a back-end to query LDAP directly or can go to PAM for the information. i.e. SSH keys, Kerberos keys, passwords, server configurations, home directory locations (for autofs), etc. Don't be scared away from OpenLDAP. It's powerful, flexible, and reliable... in my experience. Chad
