-	 * set the client's trans_conn to the proxy's trans_conn and
-	 * after CheckAuthorization the client's trans_conn will be
-	 * restored. 
-	 *
-	 * If XDM-AUTHORIZATION-1 is being used, CheckAuthorization
-	 * will eventually call XdmAuthorizationValidate and this
-	 * later function may use the client's trans_conn to get the 
-	 * client's address.  Since a XDM-AUTH-1 auth string includes 
-	 * the client's address, this address is compared to the address 
-	 * in the client's trans_conn.  If the proxy and client are 
-	 * on the same host, the comparison will fail; otherwise the
-	 * comparison will fail and the client will not be authorized
-	 * to connect to the server.
-	 *
-	 * The basis for this additional code is to prevent a
-	 * NULL pointer dereference of the client's trans_conn.
-	 * The fundamental problem - the fact that the client's
-	 * trans_conn is NULL - is because the NewClient
-	 * request in version 1.0 of the LBX protocol does not
-	 * send the client's address to the server.  When the
-	 * spec is changed and the client's address is sent to
-	 * server in the NewClient request, this additional code
-	 * should be removed.
-	 *
-	 * See defect number XWSog08218 for more information.
