Exception explanation

[ryan.tyer]

I'm converting an database based authentication system to acegi and I'm getting the following exception when attempting initial access to a secured resource. I note that it is a debug level statement, so is this to be ignored?

This exception can be safely ignored. It's quite normal, as the authentication process has to start at some point. This is the exception that causes authentication to commence.
