I need some usermanagement for a serverfarm of +/- 30 linux servers. Normally I would think of something like LDAP, but we don't want to rely on a global server to which we need to authenticate, in case of downtime or broken connections.
So I was thinking of writing some scripts that synchronise /etc/passwd and /etc/shadow and checks if homedirectories exists. Including the posibility to exclude some users at some of the servers.
But... I couldn't imagine that I'm the only person in the world that would need something like this. So does someone know an opensource project that does such a thing?
