I want to start by saying how much I appreciate you sharing your expertise.
After creating successfully the essential scripts, then changing the "Authentication Schemes" to Custom (My Auth) and login as the "admin" it popped up this message "You are not authorize to view this application, either because you have not been granted access, or your account has been locked..."
"Access denied by Application security check". Is there anything I might have overlooked during the process? Please advise.
