I'm looking a wiki or share experience for replace NIS authentication by
an existing Active directory Server (W2003). The problem is on the
management of id and gid. 
How to move 1000 actual NIS users to AD ?
How to keep the same id and gid for this 1000 users ?
What's happen with nfs linux server and acess with gid and/id ?  
Use the same user/password for linux and Windows clients

We test a solution who work very well. It's Centrify comercial software
http://www.centrify.com/directcontrol/overview.asp . But we are looking
a freeware solution. (kerberos ? openldap ? pam ? ...)
Does someone has already successfully replace NIS by Ad authentification
with freeware solution ?
