Error Message At Login for Not Authorized

Currently, if a user does not have access to the environment they're trying to log in as, no error or informational message is received. The Loading screen just continues to spin. Not that Agency UI team is implementing FAST cases into MacCentral Pending Business, they provided feedback that it is difficult for user to know if they'll be redirected to FAST or not.

We should have an informational message display so the user knows that they do not have access to view the FAST environment they're trying to use, otherwise it just looks like there was an issue with the page loading. Now that FAST cases will appear on MacCentral, we'll likely run into this more often.
