Goal

Environment:
==========
MP configuration,  AIX 5.1 (32 bit)
Master - Tuxedo 8.1 (RP#177)
Slave - Tuxedo 6.5 (RP#478)
PMID and TMLOOPBACKMP are defined 

Problem description:

Customer is using  SECURITY set to USER_AUTH.
APPKEY gets broken  when the caller is a Tuxedo 6.5 native client and the service runs on the Tuxedo 8.1 side (master
node).
The test results as following:

Tuxedo 8.1 client -> Tuxedo 8.1 service = OK
Tuxedo 8.1 client -> Tuxedo 6.5 service = OK
Tuxedo 6.5 client -> Tuxedo 8.1 service = wrong, -2147483648 is returned
Tuxedo 6.5 client -> Tuxedo 6.5 service = OK
When SECURITY is set to ACL and MANDATORY_ACL it works fine in all scenarios above. 
Only this one direction didn't work for NONE and USER_AUTH.
