IAuthenticationPlugin wants None and not None, None

[SauZheR]

I found that your implementation of autenticateCredentials returns None, None instead of None as pretended by IAutenticationPlugin.

 def authenticateCredentials( credentials ):

        """ credentials -> (userid, login)

        o 'credentials' will be a mapping, as returned by IExtractionPlugin.

        o Return a tuple consisting of user ID (which may be different
          from the login name) and login

        o If the credentials cannot be authenticated, return None.
        """
That yield PAS (PlonePas-4.0.6/gruf_support.py line 39) to understand as FOUND user when testing authenticateCredentials for each autenticator in the stack.

Why does not it returns simply None when user isn't in that ldap plugin?

Thanks for the bug report. The issue has been fixed and a new version, 1.14, is now available on PyPI.
