Fixes #58

Changes proposed in this pull request:

checks the the BasicAuth URL without credentials to make sure that the backend server is performing authentications.

In a modern environment, the performance hit is minimal as the backend server is only queried on a new session login. Afterwards the backend server is not being queried until the session logs out.
