Hi,
I am using samba on RHEL 5 or 6 for file sharing purpose.
The setings are default.
security = user
passdb backend = tdbsam

When I want to add a user with smbpasswd -a it needs the UNIX user created first. So I create accounts this way :
# useradd user1
# smbpasswd -a user1

This way each samba account has a matching UNIX account and I can confirm it by running :
# pdbedit -L
It shows samba account with corresponding unix UID.

The thing that I don't understand here is the usage of /etc/samba/smbusers.
All of samba users are already mapped. Why do I need this file and how can I test usage of this file?

Thanks.

5 or 6 ? what is it
the procedure chanced

see " man usradd "
and see the release notes for RHEL 6.4 on the chances from 5.9
https://access.redhat.com/site/docum...tes/index.html

Actually I am working with redhat 5.5 and redht 6 is not the case.
Also I cannot see anything regarding samba in "man useradd"

what version of windows is this ?
98,xp,vista,7,8,winserver 2003,2005,2008,2010,2012 ? what

I am using a Windows 7 as client but it does not matter.
In a simple file sharing with "security=user" and "passdb backend = tdbsam", every user logs in with its own samba user&password and samba users are already mapped with unix users as I mentioned in the first post.My question is : what is the usage of smbusers in this case.
