//       token will be in the form of a NULL terminated string.
//
//    pAuthTokenBufLen -
//       Pointer to integer that contains the length of the
//       buffer pointed at by pAuthTokenBuf. Upon return of the
//       function, the integer will contain the actual length
//       of the authentication token if the function successfully
//       completes or the buffer length required if the function
//       fails because the buffer pointed at by pAuthTokenBuf is
//       not large enough.
//   
// Returns:
