The approver for a workflow that was initiated by an un-authenticated user,
receives the following error (in a Windows Internet Explorer popup window)
upon opening up "My Tasks"

"an error occurred Control instantiation of JUICE.DNDisplayCtrl failed.
(Object expected). Please contact your system administrator. Detail can be
found in the console."

I don't find anything in the logs (perhaps that not "the console?), but I do
notice that the recipient, "GuestUA" cannot be resolved to a DN on the my
Tasks page. If I acknowledge the error twice, it disappears and the
workflow functions.

Then, after completing ("Submit") the workflow, I get the same two errors on
the acknowledgement of successful completion.

Any ideas?
