For the record, cred was designed by glyph and me. And we chose the
names together, and they make a lot of sense, we didn't choose them
(just) because they sound cool.

You would be implementing a credential checker. You write a IIRC check()
method that accepts certain credentials objects that comply to specific
interfaces (e.g. IUsernamePasswordCredentials) call methods and lookup
attributes on them, and then return a Deferred of either a string which
is their avatar id (i.e. unique ID representing the user) or a Failure.

So, you need to implement one method.
