Hi, Vadim
Once customers learn how to do things ... SAP will come up with their big idea and change everything without documentation. I guess they want to keep my job secured. 
I did not see any SLD related parameter under "XPI Service: AII Config Service". That is supposed to be where the exchange profile is. But I found the SLD self registration parameters under service "XPI Service: CPA Cache" though. That makes me very uncomfortable as I am not sure where else I am missing. Any other idea?
Thanks,
Jonathan.
