NFS mounts extra home folders on login

apotrebka · 03-18-2009, 10:39 AM

Hi there everybody,

On our network, we authenticate our users via LDAP and use autofs to mount their home directories. This works fine in Fedora 8. However, in Fedora 10, when the user logs in, it also mounts the home folders of the users that previously logged onto the system as well.

This is what I see when I login as "user1" on Fedora 10

Code:

[user1@workstation etc]$ w
 14:27:50 up  6:47,  3 users,  load average: 0.24, 0.13, 0.09
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
user1   :0       -                13:32   ?xdm?   4:00   0.10s /usr/libexec/gdm-simple-slave --display-id /org/gnome/DisplayManager/Display1 --force-active-vt
user1   pts/2    :0.0             14:13    0.00s  0.28s  0.06s w


[user1@workstation etc]$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda2             10241088   3554760   6686328  35% /

                     1465099264  78475264 1386624000   6% /home/user1
10.87.0.10:/var/home/users/user2
                     1465099264  78475264 1386624000   6% /home/user2
10.87.0.10:/var/home/users/user3
                     1465099264  78475264 1386624000   6% /home/user3

When I unmount the extraneous volumes, they are remounted within about 5 seconds. If I log out "user1", all volumes are unmounted.

This only happens on Fedora 10 workstations.

I also get these lines in "lsof | grep user1" on the workstations

Code:

gnome-ses 14393    user1  cwd       DIR       0,23     1736   38935 /home/user1 (10.87.0.10:/var/home/users/user2)

Note: I am accessing the user1 folder but it seems to look to the NFS resource for user2

I get those lines for any open file on the NFS share.

/etc/auto.master

Code:

/home	/etc/auto.home	--timeout 300
+auto.master

/etc/auto.home

Code:

*	-rw	10.87.0.10:/var/home/users/&

This only happens when I login to Gnome. When I'm in runlevel 3 and log in via text, this doesn't happen.

NFS server:
Fedora 8
kernel-2.6.25.4-10.fc8

Workstation
Fedora 10
kernel-2.6.27.9-159.fc10.i686

If anyone has any insight on the problem, it would be very much appreciated

Thanks!

What do you mean here? So it basically means the users were not logged off. So your problem might not be with autoFS, but with gdm. users are not being logged off completely.

Might want to consider NIS maps

I found out that its gdm-user-switch-applet thats making the calls to mount the other home folders. It's no big deal for me to get rid of it so its I guess resolved in my case.
Still don't know why it was calling for information from the other home folders though.
