Add auth info in basic callback

At the moment you are not taking info in basic auth callback. So extra information about authenticated client cannot be passed to req.authInfo object.
I changed code as follows.
this._verify(userid, password, function(err, user, info) {
if (err) { return self.error(err); }
if (!user) { return self.fail(self._challenge()); }
self.success(user, info);
});

I am sure others would also benefit if you change code as above.

Start at the basic authentication callback and trace the verify callback through the success path. Confirm that the extra info argument is passed with the authenticated user and becomes available on req.authInfo; the issue does not name a file or test to run.
