    Problem with getting a service ticket - ignoring host name?

    843810
      Hello,
      I've been struggling with this for several weeks on and off. The latest issue I have, is that when I try to obtain a service ticket it replaces the hostname I use with the ip address of the server. This then results in a 'Server not found in Kerberos database' exception.
          public static void main(String args[]) {
              try {
                  org.ietf.jgss.Oid[] desiredMechs = new org.ietf.jgss.Oid[1];
                  desiredMechs[0] = new org.ietf.jgss.Oid("1.2.840.113554.1.2.2");
                  GSSManager manager = GSSManager.getInstance();
                  GSSName clientName = manager.createName("MontgomeryB@LAB2K.NET", GSSName.NT_USER_NAME);
                  GSSCredential clientCreds = manager.createCredential( GSSCredential.INITIATE_ONLY);
                  GSSCredential clientCred = manager.createCredential(clientName,
                  8 * 3600, desiredMechs[0], GSSCredential.INITIATE_ONLY);
      
                 GSSName serverName = manager.createName("*HTTP@poe3b.lab2k.net*", GSSName.NT_HOSTBASED_SERVICE);
