NetWare 6.5 SP7

I setup a printer, it prints fine. I then decide to check the secure

It now prompts me for a username/password, which is expected. However, it's
not recognizing the admin user/passwor combination. I've tried full
context, still errors out, while trying to print a doc.

I then uncheck the secure option, applied the change, and it's now still
prompting me to authenticate!

I've tried deleting/recreating the printer object in the tree, as well as,
in the iPrint client. Same result.

How do I shut off the secure authentiction option?

Thank you for your help,
