This seems to be a race condition between obtaining master domain information and group request. It works fine when master domain information process is finished before group request occur and it fails otherwise.

Patch c2aeea38addda1a07e60adbc3451f11b640f7bf1 makes the group resolution much more likely, but it does not fix the issue. It works about 98/100 attempts in my environment with this patch.
