netware access without NC

Hello,

Lot of my users need to access Netware from Home thru' VPN. We don't want to
force these users to install NC at home. How do they access it without NC?

I tried setting up simple password which didn't work. CIFSCFG.txt issue?

Currently I have:
O=contextname
OU=IT.contextname

Please help.

Thanks,
Kris
