Hi Folks,
a little update on this epic saga.
I managed to confirm (via "klist") that on the backend the Linux ABAP Server knows the service user name "SL-ABAP-TST".
So I recon it must be the SAPgui which has a problem here, and I enabled the trace files on it to be sure.
Here is the output
errorlog.gui:

Could it be that I require SAP's Secure Login Library for this to work?
I am trying to "patch" the standard SAPgui with the SSO libs here, but am not sure if this is workable or not.
