Customer has a CORBA client/server application. An application process, named DSSserver, terminates at start-up. The
DSServer's Server::initialize() is allocating a C++ object and calling TP::create_active_object_reference() with that
allocated pointer. This DSServer uses LDAP client, but not Oracle or DB2 client.

Here is the Stack Trace:
t@1 (l@1) program terminated by signal SEGV (no mapping at the fault address)

Interesting facts about this issue:
1. This problem only happens with create_active_object_reference(). If they change it to create_object_reference(),
the problem disappears.
2. This problem also happens only when security is set to USER_AUTH. If set the security to NONE, problem disappears
(server doesn't crash).
3. The problem also disappears when Request Level Interceptor (RLI) is not registered. 

Customer wants to use create_active_object_reference() with SECURITY set to USER_AUTH and with RLI registered. In
which case, the DSSserver is failing.
