[Desktop-packages] [Bug 877766] Re: lightdm login fails with NFS home and strict (mode 0700) permissions
robert, I've prepared a new upload for precise with a patch that moves the chdir syscall after the setuid call. On my test machine, this allows users to login with strict home permissions. See the attached bzr branch. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/877766 Title: lightdm login fails with NFS home and strict (mode 0700) permissions Status in Light Display Manager: Confirmed Status in “lightdm” package in Ubuntu: Triaged Status in “lightdm” source package in Oneiric: Triaged Bug description: Lightdm appears not to be able to log in a user if all of the following are true: 1.

Apologies, this one fell through the cracks. I've committed this change to upstream lightdm, and it will be in versions 1.0.8 and 1.1.4. ** Changed in: lightdm (Ubuntu) Status: Triaged = Fix Committed ** Changed in: lightdm Status: Triaged = Fix Committed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/877766 Title: lightdm login fails with NFS home and strict (mode 0700) permissions Status in Light Display Manager: Fix Committed Status in “lightdm” package in Ubuntu: Fix Committed Status in “lightdm” source package in Oneiric: Triaged Bug description: Lightdm appears not to be able to log in a user if all of the following are true: 1.

[Desktop-packages] [Bug 877766] Re: lightdm login fails with NFS home and strict (mode 0700) permissions
This may be the same problem I reported in Bug #914674
I notice this behaviour as well:
[+16.19s] DEBUG: Dropping privileges to uid 6057
[+16.19s] DEBUG: Adding session authority to /npdisks/home/jb/.Xauthority
[+16.20s] DEBUG: Restoring privileges

'gnome-session --session=ubuntu'
[+16.20s] WARNING: Failed to change to home directory /npdisks/home/jb:
Permission denied
It looks like it restores privileges to root before trying to change to
home directory and this naturally fails since root has no privileges
there.
It looks like session.c tries to change working directory _before_ it
tries to change user:
session.c:
Line 409:
/* Change working directory */
if (chdir (user_get_home_directory (user)) != 0)
{
g_warning (Failed to change to home directory %s: %s,
user_get_home_directory (user), strerror (errno));
_exit (EXIT_FAILURE);
}
/* Change to this user */
if (getuid () == 0)
{
if (initgroups (user_get_name (user), user_get_gid (user)) 0)
{
g_warning (Failed to initialize supplementary groups for %s: %s,
user_get_name (user), strerror (errno));
_exit (EXIT_FAILURE);
}
if (setgid (user_get_gid (user)) != 0)
{

_exit (EXIT_FAILURE);
}
