LDAP configuration

I’m trying to setup a new OF server. I’m currently running a small server using local DB to store ID’s … I’ve been asked to extent the servers use to a group of new facilities … so rather than manage 200 IDs I figuired I’d use AD.

My question is re: Base DN … in a “std” AD all the users are in the USERS OU . In our AD, each plant as it’s own OU with a USERS sub OU … for my plant is FRA and I have a USERS OU … I’m adding NOG which has a USERS OU … so how do I specify this … ?
