We deployed ACS 4.0 (NOT ACS SE) and WLAN in our corporate network.
Our ultimate goal is to have each staff authenticated against our AD via ACS using EAP-TLS.
We managed to get PEAP working successfully, but failed with EAP-TLS.
From the log we noticed that when PEAP is used, ACS forward username to AD in domain-qualified format (domain\user),and authentication is successful.
External DB [NTAuthenDLL.dll]: user [email protected] was not found
Unknown user '[email protected]' was not authenticated" . Any workaround for this?
Can anyone throw some light here?
