I'm starting to see issues where a computer with a standard user is logged in, and when an authorization window pops up, like when you're changing system settings or authorizing an install, the computer will not accept the admin username and password. If I log into the same computer as the admin, it accepts the password without issue. I created a second admin account, and it is having the same issue when a standard user is logged in. I've checked to make sure the admin accounts have a securetoken granted, and they do.
Has anyone else ran into this problem and found a fix?
