+//
+//  Arguments: 
+//    pServiceAtHostName -
+//       Pointer to NULL terminated string that contains the
+//       service@host name to which the client is trying to
+//       authenticate. Note that the host portion of the name
+//       can either be a DNS name or a dotted IP address.
+//               
+//    pAuthTokenBuf -
+//       Pointer to buffer that will receive the authentication
+//       token. The length of this buffer is specified by the
+//       pAuthTokenBufLen parameter. Note that the the authentication
+//       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:
+//    Casa Status
+//                           
+// Description:
+//    Get authentication token to authenticate user to specified
+//    service at host.
