Hi
Are you using the AD connector for users and groups?
S-1-5-11 is the SID for "Authenticated users", the reason why sometimes you see the SID and not the name is because in the Active Directory there are actually 2 objects with that SID, one in Foreign Security Principals, and it has its name field set to the value of the SID, so when we fetch an object by SID from the Global Catalog, it may return that one first.
It's also possible that if it is taking a long time to fetch objects from the Global Catalog, that you would see SIDs in the web access rules, since that is what is stored, and when you view the Web Access Rules tab, it fetches the objects for all the SIDs in all the rules to display them. If this fetch takes a long time then you'd see the SIDs.
So it sounds like the main problem is speed of response from the Global Catalog server. Are you on a WAN accessing remote Domain Controllers / GC servers? If there is a local GC server you can use, you may be able to force WinGate to use it by following the instructions here:
