[Samba] Mounting Samba Share using linux login

Windows users are able to mount samba share using windows. But for
linux user, we need to create credentials file, to mount samba share
e.g:

//servername/file_store /home/user/Desktop/file_storage smbfs
credentials=/root/.smbcredentials

Is it possbile to change the credentials to something like windows
users (for example credentials=unix user) so as the mounted share
would depend on who login the linux box?

This is important as I want to let user change their own password, and
keeping .smbcredentials in user's home directory would be insecure.
But to keep the .smbcredentials at root would mean to give user admin
rights in order to change password file.

David

You can make your own credential file as a batch file:

@echo off
rem my special batch file
set specialusername=abc
set specialpassword=topsecret

call this batch file within the logon batch file
and then use %specialusername% and %specialpassword%

Hi Helmut,
Thank you very much for your reply. But could you elaborate further as
I could not understand how to do it:

1. What credentials should I put in fstab?
2. Do you mean the batch file is an executable plain text file
executed during login?

Sorry - I've written a batch file for DOS/Windows.
Linux users should use a shell script.
There are several options to run this shell:

/etc/profile.d/<specialscript.sh>
(is run when the user logs in)
Icon on the desktop
(must be clicked to run)
command in ~/.Xdefaults
(is run when an X session is started)

None. "/etc/fstab" is not necessary for mounting.
And the special user share can't be mounted via the (global) "/etc/
fstab".

Which linux distribution is installed on the clients? Which GUI is
installed: KDE or something else?

That is one way.

pure shell script:

#! /bin/bash
Credfile=~/.sambacred
test -s $Credfile && source $Credfile || exit 1
# and now the username and the password for the shares on the
# server are known
mount.cifs ...
#


Viele Gruesse!

Although I have not done this yet (waiting for linux dfs client to
work 2.6.26 kernel), I believe pam_mount is also a good option for
this purpose:

http://pam-mount.sourceforge.net/

Only root can change these options.
If I put my script into the profile way or into .Xdefaults (p.e.), then
I can mount several foreign shares on several servers without asking my
root. Ok - "mount.cifs" must have set the "SUID" flag.

pam_mount is the best solution as it mounts the sahre with the unix user
credentials.

Yes, I think pam mount is what I need. I will study it and report if
it is successfull.

Anyway, thanks also for Helmut for the idea.

Regards,
David

I have followed below guidelines which is a little bit outdated:
https://wiki.ubuntu.com/MountWindows...2b50541c417d95

It is mounted successfully by editing /etc/security/pam_mount.conf.xml
instead of /etc/security/pam_mount.conf, and follow the direction in
the /etc/security/pam_mount.conf.xml.

Now user could change samba password using usermin, and then followed
by changeing its own password to match, and the share would mount
autimatically.

Thanks again,
David
