Hello all, I'd like to use machine account authentication and machine credentials WITHOUT using certificate but only with the machine AD password. I've configured the OAC, but if I reboot the station, the authentication fails: Info AUT23457 2008-11-25 15:44:29 - rtlbruinfranet01 - [0.0.0.0] RTLNET\rtlbrulap1365$(Realm_RTL_Users)[] - Login failed using auth server Active Directory (Samba). Reason: Failed Info AUT24327 2008-11-25 15:44:29 - rtlbruinfranet01 - [0.0.0.0] RTLNET\rtlbrulap1365$(Realm_RTL_Users)[] - Primary authentication failed for RTLNET\rtlbrulap1365$/Active Directory from 00-0D-56-B2-13-B3 If I use an AD user login/password, the authentication is successful (so I guess the UAC is correctly communicating with the Active Directory DCs): Info AUT24326 2008-11-25 15:51:02 - rtlbruinfranet01 - [0.0.0.0] RTLNET\stest(Realm_RTL_Users)[] - Primary authentication successful for RTLNET\stest/Active Directory from 00-0D-56-B2-13-B3 Am I missing something ?
