When I installed NW 6.5 and got to the configuration screen I specified that
iFolder should reside on my USERS volume rather than the sys volume. Now
that I have configured iFolder and enabled users none are able to login.
They either get authentication failed (-40) or (-23) or (-25). I thought it
might be because there wasn't a folder named iFolder on USERS so I manually
created one.

Still not working. Any help would be greatly appreciated.
