Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of WebSphere eXtreme Scale        *
  ****************************************************************
  * PROBLEM DESCRIPTION: A "NO_PERMISSION" exception displays    *
  *                      with the following                      *
  *                      message: "Unauthenticated               *
  *                      credential found, client auth           *
  *                      required by client or server."          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  WebSphere Application Server security context was not available
  on client thread. This client request is therefore rejected by
  server because authentication is set to 'Required' on server sid
  

Problem conclusion

• To prevent the "NO_PERMISSION" exception, this fix adds
  security context on all client threads to correct this problem.
  
  A future cumulative fix corrects the problem for WebSphere
  eXtreme Scale Versions 6.1, 7.0 and 7.1.
