User cannot login or misses resources provided by loginskript or group policies
User has too many group memberships for default kerberos token size
Errormessage upon user-logon:
"Error browsing user memberships - Error loading user object for user: <DOMAIN>\<USER>." and something like 'not sufficient memory for this task.'
Other errors can be, that group policies (GPO) are not applied.
The solution can be to change the value for "MaxTokenSize" in your registry:
DWORD "MaxTokenSize" --> 0xFFFF (decimal 65535)
!!! this key changes kerberos authentication. The default value is 12000 (decimal).
!!! changing this key to values greater than 0xFFFF (or 65535) can cause "Timeout expired" errors in MS SQL Server communication or WBEM / RPC issues as SMS administrator
