YAGA: Ranks deny sign-in
So I awarded someone the rank of Administrator, and found out that he couldn't log in after. I did some troubleshooting, and both Administrator and Moderator prevented sign-in. I checked the roles and they all have Garden.Signin.Allow checked. It works for me, but I'm using an admin account.
Anyway, I tested with another account and the same thing happened. I give it Rank: Administrator (which was imported from the zip file) and it disallows sign-in.
