Back when I was setting up NW6.5sp5 servers I had found the following in
this form:

"Between NW6.5 sp4 and sp5, the ldap modules that
iPrint uses removed the requirement upon the ldap authentication for the
existence of the UID." - in a message from iprintrox dated 7/17/2006

And indeed, NW6.5sp5 iprint works without UIDs here.

Now in testing for NW65sp7, it appears the UID requirement is back. Can
this be fixed again so that UID is not required?
