I don't believe this will work with NDPS printing - you'll need to create an old
fashioned queue-based setup.
A colleague showed this 'vulnerability' to me a little over 3 years ago on a
4.11 network. However, he was using his own software that was authenticating
via API calls, rather than via client32. I thought it was interesting at the
time, but assumed it was a known bug after hearing of it from a few other
sources.
I have just replicated it now on both 4.11 sp9 & 5.0 sp6a servers. However,
print server objects created by AXIS NetPilot or HP-JetDirect don't work - they
give a 669 error (effectively, incorrect password); that is as opposed to a -601
for object not found.
It may fail using Netware clients as they request a number of properties of the
authenticated user that might not exist in the schema for a print server object.
I tested using "ncpmount" from a Linux box.

Tested the Exploit on Netware 5.1 SP2 with the context and username set to the
print server's context and username. I got an error logging in. No password was
set for the print server (I don't think its possible). The printer was an NDPS
printer. Does this only happen with "public access" printers, or was it a
different service pack you tried it on?
