Hi Mark,

Can you also send the related snippet from config (everything in the
'Plugin::Authentication' key)?
That will tell us what store and credential you are using, so we don't
have to guess :)

The code to the authenticate call looks fine, so perhaps something in
the config is the culprit.  Obviously we want the error messages to be
more helpful, so I'd like to also solve why you aren't getting a
helpful message, too.

Thanks,
