[pmwiki-users] Authentication Error

[The Editor]

I got the following warnings trying to login to my demo site using
FAST Data. It doesn't seem to do it on my production site, but maybe I
don't see them.  Any thoughts?

I attached below a copy of the login script.  On my home machine it
logs in perfectly (though it doesn't grant password permissions, just
identity based ones.  Which is fine... But would like to fix it still.
 But first things first.

These error messages. Any clue what they mean?

Cheers,
Caveman
