Some applications have features that read the token-groups-global-and-universal (TGGAU) attribute on user account objects or on computer account objects in the Microsoft Active Directory directory service. Some Win32 functions make it easier to read the TGGAU attribute. Applications that read this attribute or that call an API (referred to as a function in the rest of this article) that reads this attribute do not succeed if the calling security context does not have access to the attribute.
By default, access to the TGGAU attribute is determined by the
Permission Compatibility decision (made when the domain was created during the DCPromo.exe process). The default permission compatibility for new Windows Server 2003 domains does not grant broad access to the TGGAU attribute. Access to read the TGGAU attribute can be granted as required to the new Windows Authorization Access (WAA) group in Windows Server 2003.
