* Subject in the current access control context. If the server is merely
* interested in using a principal based policy in its local JVM, then
* it only needs to provide the GSSName of the client.
*
* The elements from the GSSName are placed in the principals set of this
* Subject and those from the GSSCredential are placed in the private
* credentials set of the Subject. Any Kerberos specific elements that
* are added to the subject will be instances of the standard Kerberos
* implementation classes defined in javax.security.auth.kerberos.
*
* @return a Subject with the entries that contain elements from the
* given GSSName and GSSCredential.
*
* @param principals a GSSName containing one or more mechanism specific
* representations of the same entity. These mechanism specific
* representations will be populated in the returned Subject's principal
* set.
*
* @param credentials a GSSCredential containing one or more mechanism
* specific credentials for the same entity. These mechanism specific
* credentials will be populated in the returned Subject's private
* credential set. Passing in a value of null will imply that the private
* credential set should be left empty.
