I'm having some trouble setting up security. I've been through the documentation and examples a couple times and believe I have everything setup correctly. The problem I'm having is that the app in not authenticating the user. I'm not getting any exception, only a message form saying "the given credentials could not be authenticated...". I've double checked the settings in the security editor everything looks fine. Could there be anything else that I've been overlooking, or something that is commonly overlooked?
