[SAGE] Help with centralizing account management

[Paul Dlug <paul@nerdlabs.com>]

I need some help finding a solution to manage user accounts from a central 
location. Our environment is composed of Solaris and FreeBSD servers (some 
scattered linux as well) with a rollout of around 20 FreeBSD desktops 
planned. NIS+ is currently being used on Solaris, the FreeBSD hosts are 
maintained manually since they're primarily servers with one or two user 
accounts. There is a planned migration to LDAP in the next few weeks as we 
move toward Solaris 9. I tested pam_ldap with FreeBSD and it works, however a 
password file entry is still necessary so it doesn't really solve the 
problem. LDAP seems like it's the right choice and it works well under 
Solaris however I don't see mature support for it under *BSD and linux. Can 
someone recommend a solution?

Thanks,
Paul
