3.1.5.1.7 SamrOpenGroup (Opnum 19)

  • Article

The SamrOpenGroup method obtains a handle to a group, given a RID.

 long SamrOpenGroup(
   [in] SAMPR_HANDLE DomainHandle,
   [in] unsigned long DesiredAccess,
   [in] unsigned long GroupId,
   [out] SAMPR_HANDLE* GroupHandle
 );

DomainHandle: An RPC context handle, as specified in section 2.2.7.2, representing a domain object.

DesiredAccess: An ACCESS_MASK that indicates the requested access for the returned handle. See section 2.2.1.5 for a list of group access values.

GroupId: A RID of a group.

GroupHandle: An RPC context handle, as specified in section 2.2.7.2.

This protocol asks the RPC runtime, via the strict_context_handle attribute, to reject the use of context handles created by a method of a different RPC interface than this one, as specified in [MS-RPCE] section 3.

Upon receiving this message, the server MUST process the data from the message according to the constraints in section 3.1.5.1.6, with the following values:

  •  Target-Rid: GroupId

  • Target-Object-Type: a group object (that is, a database with the objectClass group or derived from group) and groupType containing GROUP_TYPE_ACCOUNT_GROUP or GROUP_TYPE_UNIVERSAL_GROUP.
