SCO Mapped Drive

We are running SCO OpenServer 5.0.7. Some of my users have drives mapped to the SCO box, some don't. The consultant, who setup the mapped drives, is long gone, and I need more users to have drive letter mapping.

When I try to map a drive via windows, I am repeatedly asked for a user/password, it will not connect. I have a valid user/password that lets me login via putty or some other terminal emulator.

My guess is this is a rights issue, so is there some comparison tool/gui that I can use to compare rights for users?

All suggestions appreciated.

How are those drives exported to Windows? SMB via Samba? Some other CIFS system? NFS with additional software on the Windows PCs?
Are the mapped drives unique for each user or do they use common ones?

As for rights comparison, usually a ls -l <dir> and comparing the first column does the trick.
