@prabhjyotsingh i was strugling few days as my groups were not honored and
found this thread :)
I`m having issues described by @ChrisMcVey - using microsoft AD, UPN is not
the same as username + activeDirectoryRealm.principalSuffix
I was not able to find any follow up, is there anything i can do to help
solve this?---
