ACS V3.0 and UPN logon name

lldemeyer

We have ACS V3.0 on Win2000 Server(AD) & WinXP client. The client is configured for LEAP + 'Use windows user name and password' setting .

-> When using the pre-Win2000 usernames authentications is OK . ex.: username :hpgedadm

-> When using the UPN (user principle name) logon names the authentication fails .

ex.: username : dirk.geenen.admin@interbrew.net

On the ACS server the Authentication-failure code: Radius extension DLL rejected user

On the Windows 2000 AD no corresponding authentic failure is seen in the event logging .So apparently the ACS radius server has a problem with UPN's. Is there a setting or is this not supported on V3.0 or..?

Thanks,

Luc.

Cisco Secure ACS does not support the user@domain (UPN) format of qualified usernames when

authenticating users with Windows user databases of any type, including local and domain SAM

databases and Active Directory databases.
