Red Hat Bugzilla – Bug 3271
gdm-1.1.0-35 silently fails if home directory is 777

If a user with a world-writeable directory tries to log in,
gdm will accept their password, clear the screen as if to
start the session, and then immediately kill the session and
return to the login box. No error messages are presented,
and we couldn't even find any explanation in a log file
I'm not sure if the bug is in gdm itself or the login
scripts that Redhat 6.0 uses. I have also submitted this as
a Gnome bug.
This is listed as Gnome bug report #1393
I have verified this to be true on a test lab machine with a stock 6.0
intall. I created a sample user account. chmod 777 that users home
directory. Then using gdm attempted to login as the sample user with
out success. It would come back to the gdm login screen. I then chmod
755 the home directory and then was able to successfully login to the
This might just be a good security measure - with xauth style
security, a world-writeable home directory is a really bad idea.
If this is correct behaviour, then the "fix" should be to make
sure the user understands why they weren't allowed to log in.
Some sort of visible error message...
Assign to mkj for now.
Try getting the gdm-2.0beta2-13 from RHL 6.1
