I've been working on a construction to achieve mounts on a per-user basis.
It's based on a few things:
- a tree in the homedirectory of the logged in user, representing the
Windows network. The shares are
symlinks pointing to the automount path: /mnt/autofs/network/:
/home/sbon/Global Network/Windows Network/BONONLINE/LFS20060812/public ->
/mnt/autofs/network/smb:[EMAIL PROTECTED]@BONONLINE%public
Now this autofs directory/key (/smb::[EMAIL PROTECTED]@BONONLINE%public)
does have all the information in it necessary to do a cifs mount.
I can do this because the automounter does not understand the smb
protocol. It just passes the parameters
to the mount program.
Earlier I've been working with a construction where the automounter had
to be started for every user. This new construction does not need this.
Futher this Windows Network representation is build by scripts which
discover the network periodically.
- my auto file looks like:
* -fstype=network :/&
Very short and simple!
Earlier I've been working with submounts ( Ian do you remember this?)
Look at the filesystem network. It does not exist, but I've created a
mount.network wrapper:
- a mount.network wrapper. It's just possible to use this wrapper in
stead of a "normal" filesystem!!
This wrapper does find all the information necessay out of the key
(/smb::[EMAIL PROTECTED]@WORKGROUP%share) to call the real mounter mount.cifs!
The automounter is started at boottime with a rc script.
There is only one point which is difficult: for which users the network
representation has to be build.
Any advice appreciated. I'm using a special module in PAM for that
purpose right now, but maybe
there are other ways to do this.
My most recent howto is on:
http://linux.bononline.nl/linux/automountsmbshares/automountsmbshares-page01a.php
An older version is available at:
http://www.howtoforge.com/automatic_discovery_mounting_smb_networkshares
This latest version I will update as soon as I'm ready with the
documentation on my own website.
This construction is working very good. Try it. If you need any help you
can contact me.
