I am not sure if the above is what you used, but I know it exists, but personally myself didn't have success with it, but on the other side of the coin I may have attempted using it for a total of an hour.
What I ended up doing was getting the
ncpfs package and mounting them manually kinda like mounting a cdrom or a floppy. The parameters are different of course, but same idea.
hope that helps ya a little.
p.s. if that novell client above is what you've attempted to use, did you by chance read the first FAQ
