2.120 Attribute primaryGroupID

This attribute specifies the relative identifier (RID) for the primary group of the user. By default, this is the RID for the Domain Users group. The user is a member of its primary group, although the group is not listed in the user's memberOf attribute. Likewise, a group object's member attribute will not list the user objects whose primaryGroupID is set to the group. For more information, refer to [MS-SAMR] section 3.1.1.8.2, [MS-ADTS], and [MS-ADA2] sections 2.43 and 2.45.
