220.127.116.11 Message Processing Details
Some RSM Remote Protocol functionality is provided by two parallel methods, one providing support for ASCII and the other for Unicode. The server MUST use an object's GUID to map the object to different names given via equivalent methods and perform identical operations on an object regardless of whether the method used is ASCII or Unicode.
Before processing any of the following methods, the server SHOULD obtain the identity and authorization information about the client from the underlying DCOM or RPC runtime. These methods SHOULD impose an implementation-dependent authorization policy decision before performing the function.<20>
