[cifs-protocol] primaryGroupToken

[Andrew Bartlett]

MS-ADA3 2.120 claims:

Attribute primaryGroupToken
  This attribute specifies a computed attribute that is used in retrieving the membership list of a group
  such as Domain Users. The complete membership of such groups is not stored explicitly for scaling
  reasons. For more information refer to [MS-ADTS] section 3.1.1.4.5.11 and [MS-SAMR].

However, 
MS-ADTS 3.1.1.4.5.11 claims:

primaryGroupToken
  Let TO be the object from which the primaryGroupToken attribute is being read.
  The value of TO!primaryGroupToken is the RID from TO!objectSid when there exists C in
  TO!objectClass such that C is the group class. Otherwise, no value is returned. That is, if TO is a
  group, then the value of this attribute is the RID from the group's SID. If TO is not a group, no
  value is returned when this attribute is read from TO.

The behaviour of Window 2008 appears to follow MS-ADTS.  That is, the
primaryGroupToken appears to be the RID of the objectSID for all
groups. 

Please advise, clarify or correct,

Thanks,

Andrew Bartlett
