Easy Question for you :-)

["biscut" <biscut biscut screaming net>]

When I am logged in as root then I can run:

mount -t smbfs -o username=biscut, password=password //servername/directory
/mnt/directory

but when i am logged on as another user then it doesnt work, I get "invalid
arguement" statements, it also doesnt work when I try to use "su" before
trying to run it as well, is this just a chmod problem and how can I get
round it ?? can I set +us to a file ?? or is there more to it than that ??

Thanks for your help
regards
