We recently started getting the above error on iPrint clients. Grace logins
is a feature of the netware accounts that has been around for a very long
time. Why does iPrint not authenticate when they are validly logged in
under grace logins and still have remaining grace logins? Is there any way
to make iPrint authenticate to remaining grace logins?

The dialog does not show up right away, it only shows up if you "mess"
around in iPrint when the printer status is "error" on the workstation.
