2.2.10 Group Membership

  • Artículo

This section defines settings that enable the administrator to control the membership of various groups. The ABNF syntax for the entries in this category MUST be as follows.

 Header = "[" HeaderValue "]" LineBreak
 HeaderValue = "Group Membership"
 Settings = Setting / Setting Settings
 Setting = Key Wsp "=" Wsp ValueList LineBreak
 Key = GroupNameMembers / GroupNameMemberof 
 GroupNameMembers = (GroupName / (%d42 SID)) "__Members"
 GroupNameMemberof = (GroupName / (%d42 SID)) "__Memberof"
 GroupName = GROUPNAMESTRING
 ValueList = Value / Value Wsp "," Wsp ValueList
 Value = %d42 SID / GROUPNAMESTRING
            
         
            
 GROUPNAMESTRING = 1*256(ALPHANUM / %d32-33 / %d35-41 / %d45 / %d64 / %d94-96 / %d123 / %d125 / %d126)
           

The SID element in the preceding syntax has its ABNF specification in [MS-DTYP] section 2.4.2.1.

Note that in the actual security policy, the preceding "GroupName" setting MUST be replaced by the actual name of a group whose members or membership in other groups MUST be configured. For more information, see the example in section 4.3.

The following table explains each of the settings listed.
