3.1.5.1.8 SamrOpenAlias (Opnum 27)

The SamrOpenAlias method obtains a handle to an alias, given a RID.

 long SamrOpenAlias(
   [in] SAMPR_HANDLE DomainHandle,
   [in] unsigned long DesiredAccess,
   [in] unsigned long AliasId,
   [out] SAMPR_HANDLE* AliasHandle
 );

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 2.2.1.6 for a list of alias access values.

AliasId: A RID of an alias.

AliasHandle: 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: AliasId

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