  - ### Method Detail

    - #### createSubject

          public static Subject createSubject​(GSSName principals,
                                              GSSCredential credentials)

      Use this method to convert a GSSName and GSSCredential into a Subject. Typically this would be done by a server that wants to impersonate a client thread at the Java level by setting a client 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.
      Parameters:
        `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.
        `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.
      Returns:
        a Subject with the entries that contain elements from the given GSSName and GSSCredential.
