Re: stations do not authenticate, possible bug cscsd52663

Sounds like this may be a cross forest auth issue. Check to see if the two domains are in different forests or the same forest.

Here are some URLs that will guide you through the install process. Ensure that they are followed exactly. There is a requirement to have the ACS services started as a domain admin account. I confirmed with TAC that as long as the account is a domain account with the proper permissions (in the doc) you'll be alright. I'm currently running ACS 4.2 with machine auth working successfully across forests.

Release Notes for Cisco Secure ACS 4.2:

As discussed here is the bug:

CSCsd52663 : Cross forest user/machine authentication does not work


Machine authentication may fail due to "host not found".


ACS is installed on a server that's a member of a domain in Forest 1, while pc's performing machine authentication are members of domains in Forest 2.


Ensure ACS is a member of the same forest as the authenticating PCs.
