We need centralized accounts -- Any docs for ldap passwords?

[Rob Browning <rlb@cs.utexas.edu>]

We've got a number of machines here that we need to switch to
centralized account maintenance, and I was trying to figure out what
the best solution would be.  It looks like the two main solutions
would be NIS or ldap (via PAM), but I'm having a hard time finding out
enough about the ldap solution to do a good comparison.  Is there a
good HOWTO or similar somewhere?  Is there some other solution I've
overlooked.  (I thought about just using a cron job and a sync script
to keep all the passwd/group files in sync, but that requires you to
be able to atomically update the files, and I couldn't see a good way
to do that...perhaps some trick with chpasswd/add/deluser...

Thanks
