We have a forest whose schema master is a 2008R2 DC (AD schema version if 47). I'd like to install Identity Management for Unix, but it's unclear to me whether or not this updates the AD schema. The server I plan to run IDMU and its NIS Server on is a 2003 R2 SP2 DC. The somewhat fuzzy impression I got from reading technet, etc was that it still makes some schema updates even if your DC is 2003R2+. Do I need to do this installation on my schema master first? We don't have the need to run this IDMU/NIS Server stuff on any of our other DC's.

I know for certain that a schema update had to be done on our 2003 domain. But I am not sure about 2008.

A quick way to test would be to just check your schema to see if any of these classes/attributes are part of your schema. If they are not present then a schema update is in your future.

I have checked on a test VM with a 2008r2 DC. The attributes are present in the schema. So if your schema is up to the 2008r2 level you probably don't need to do anything else.

We're at 2008 and do not have the attributes. – sysadmin1138 Oct 25 '10 at 22:13
