Goal

Requests to a remote WLE domain originating from WLS through the use of WLEC will fail on the client-side WLE domain. A
sample configuration exposing this problem could look like the following.

WLS -> WLEC -> WLE Domain 1 -> WLE Domain 2

Suppose that a servlet or EJB hosted by WLS is invoking a method offered by WLE domain 2.  The requested service is
hosted by Domain 2 and imported by Domain 1 using the /Domain feature of WLE. The application is configured to access
the imported service via a WLEC Connection Pool to Domain 1. 

The request will fail with a userlog message from the ISL on WLE Domain 1. The entire text of the message is as
follows.

ISNAT_CAT:1308: ERROR: Unofficial connection from client at //172.18.46.225:3480

Clients that connect directly through the ISL on Domain 1 can successfully access the service on Domain 2. WLEC
clients cannot.
