thank you for your fast answer!

manually mounting is working fine!

debug is /etc/security/mount_pam.conf is on!

i have a debug output in /var/log/auth.log (ubuntu)

here is say: no volumes to mount!

i guess it's not a problem with pam service or smbmount.
i must be a problem with my mount_pam.conf but i can't see it :-(

here is my log output:

i don't want this feature via ssh. only for local logins!
(/etc/pam.d/gdm)

hello together,

i am to stupid to configure pam_mount correctly.

i configurd /etc/pam.d/gdm to automount a smb share on gnome-login.

the pam entries seems to be correct (i've got entries in /var/log/auth.log)

her is my local user config ~/.pam_mount.conf:

volume user smbfs samba POST /home/martin/POST - - -

(samba = name of samber server in our network
POST = name of samba share
/home/martn/POST = mount point)

on login in get an error message:

no volumes to mount!

both config files (local and /etc/security/pam_mount.conf) are chmod 777!!!!

/etc/security/pam_mount.conf:

debug 1

mntcheck /bin/mount # For BSD's (don't have /etc/mtab)

i've tried all kinds of configuration but i never mounted a file system (i think i am to stupid!)

thanks

Hi Martin,

Try mounting the share manually first - eg.

smbclient -U userid //server/sharename

Have you added the required pam_mount lines to the appropriate service
file in /etc/pam.d.  Use the login service and test it using a console
command line login with debug turned on in pam_mount.conf to see what is
happening. There is an unresolved bug with using pam_mount with ssh so
it probably wont work logging in via ssh.

Regards

Murray
Do you have something like the following at the end of the
pam_mount.conf to actually do the mounting?

# An example using spaces:
# volume * smb krueger 'Home\ Directories' /home/& - - -
volume * cifs ldap & /home/&         username=&  - -

hi

i will a user specific mounting so the 'mounting rule' are in $HOME/.pam_mount.conf

i tried also the mounting in /etc/security/pam_mounting.conf and disabled the local user file (luserconf .pam_mount.conf) and put 'volume user smbfs samba POST /home/martin/POST - - -' into /etc/security/pam_mounting.conf

i have no idea why it isn't working!

thanks a lot!

regards

martin

The file in /etc/security should be pam_mount.conf not
pam_mounting.conf.  You should see some logging on the command line or
in /var/log/messages when the user logs in to tell you what is
happening.  If not check you have both the required entries in the file
for the service you are logging in with in /etc/pam.d.

Murray

hi

thank you for answer!

the file is pam_mount.conf not pam_mountig.conf

i only want to use pammount with gdm!

i changed to a global config and tried a local mount only

the output in /var/log/auth.log is the same

martin
