Impact of changing the domain of ACS server

[boonteongng]

THe ACS is using external windows domain for wireless user authentication., e.g domain 1. The ACS server is also in domain 1. If I move the ACS server to domain 2, can it still authenticate wireless user in domain 1 ? anything need to be changed in the ACS server ? This is ACS 3.0. Thanks

Changing the domain of the ACS erver to a different domain from the user domain should work, but there are caveats.

You will have to make sure there is a trust relationship between the two domains. This may already be the case in your environment.

There was also an advisory published about ACS 3.0 with Active Directory user authentication.

If you can not get passed the workarounds outlined in the advisory, then your best bet is to go to the most current release of ACS.
