URL logon groups are empty in SMMS

hello,

i'm trying to configure http load balancing with message server.

i've created a logon group and assigned it to url webgui in SICF

it seems to work but in sape note 751873 it is said that logon groups and corresponding urls could be loaded and checked in transaction SMMS using functions via Goto -> Expert functions -> HTTP

the problem is that, here in SMMS, my url logon groups list is always empty...

is it normal?

regards
