Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I want to enable AD (win 2008 R2) users on a linux box. The problem is that there are also local users (for historical reasons). Now I want to make sure that there is no clash in UIDs (or at least minimise the chance). The historic local accounts are all in a certain range, way below 20000. Is there a way to tell the AD "Identity Management for UNIX" role that UIDs should be above a certain number?

Any other approaches towards the unique UID goal are also welcome :)

I want to ssh into the centos client machine, using the AD accounts allready in place. So I am not looking for another directory service. –  Isaac Jun 13 '13 at 14:42
