[rt-users] ticket custom fields won't show up

[Josef]

  Hi,
     I'm trying to add some custom fields to tickets. I have created 
them, added them to a corresponding queue, set SeeCustomField to 
everyone. But still only privileged users see these fields when creating 
a new ticket. Unprivileged users don't see them, but when they fill a 
request, it returns an error, as I have set these fields to be 
mandatory. Is it possible to add this, or do have all users to use full UI?

Thanks,
     Josef
