When authenticating a user against crowd, if that user fails to authenticate due to not being permitted to access the application (that is, their username and password is correct, but they haven't been granted access to the application in Crowd), the Crowd integration client throws an ApplicationAccessDeniedException. This is then logged at the warning level in FishEye, with a message of "Problem communicating with Crowd". This should not happen, rather, it should be treated the same as if the username and password were incorrect (which currently logs a message at info saying "user not found").
