I have a custom SecurityTokenService implemented and the SPTrustedLoginProvider added to my farm. I've also implemented a custom SPClaimProvider that allows me to use the People Picker to give users permissions on the site. Everything
seems to be working fine up to a point. When I go to my site and choose the correct login method I am redirected to the STS, login there and then get redirected back to my SharePoint site. The problem is that I get an access denied error with message
'You are currently signed in as: <Unique User ID FROM STS>'. I get this even after adding the associated user as a member of the site. If I add 'All Users (Custom STS)'
as a member of the site I can login just fine.
So, what could be the disconnect between giving a user permissions and then logging in as that user?
