smbadduser problems

[James Simons]

I'm setting up a Samba server that is mainly going to be a public access 
for the folks here in the office.   I don't need ultra security, but a 
little would be nice.   To do this, I thought that I would create one 
user under RH 7.2 and then use smbadduser to create "aliases" for other 
users through smbadduser.

Take this for example

I created a user called network with asdfer as the password in Linux. 
 I'd like all passwords to be asdfer
I need for the user fsmith to have access

so I did the command

smbadduser network:fsmith
asdfer
asdfer

When I went to log into Samba it rejected fsmith and allowed me to log 
in as network.  I then created an account under Linux for fsmith and 
tried logging in, which I sold not do as their is no smbusers entry for 
fsmith.  What do I need to do to accomplish this?

Thanks,
James
