What bites is if you already have a large AD environment in place along
with legacy NIS.
It's obviously not efficient to maintain two separate environments with
many of the same usernames...
AD does have "Unix Extensions" to expand their schema to make it more
friendly for use as LDAP.. but it's pretty limited really. That and,
what if you have many legacy Unix clients that can only talk NIS
There are packages like LikeWise out there that can make this work
fairly well -- they even have a free version.
Lately I've been thinking of using something like Fedora Directory
Server to just sync up daily from AD and provide LDAP and NIS services
via some sort of shim to older Unix clients who can't handle LDAP.
Note that Samba 3.3.x integrates pretty well with AD via winbind. If
you can get good external uid mapping going you can even preserve UID's
from your NIS environments.
It's definitely not as fast as NIS though as far as responsiveness...
