Description ritz 2006-11-29 21:59:26 UTC 
+++ This bug was initially created as a clone of Bug #208148 +++

Description of problem:

This is a dup of https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=164869.

I am entering it again now as it is in RHEL4.4

In /etc/X11/xdm/Xsession, the addition of $SSH_AGENT in the following line:
     exec -l $SHELL -c "$SSH_AGENT $DBUS_LAUNCH gnome-session"

The ssh-agent executable is has its setgid bit set; this causes glibc (?) to
remove LD_LIBRARY_PATH from the environment before launching $DBUS_LAUNCH
gnome-session.

Version-Release number of selected component (if applicable):
xinitrc-4.0.14.3-1

How reproducible:


Steps to Reproduce:
1. Login via xdm
2. Open gnome-terminal
3. echo $LD_LIBRARY_PATH
  
Actual results:
<It's Empty!>

Expected results:
Anything you have set in ~/.bash_profile or /etc/profile

Additional info:
Login via a console (ctrl-alt-F1); echo $LD_LIBRARY_PATH:  Viola,
LD_LIBRARY_PATH is set.

-- Additional comment from mcepl on 2006-11-24 11:45 EST --
According to the tmraz (owner of ssh-agent) there will be no chance of changing
ssh-agent being sgid, so probably the only solution is to follow comment 4 and
change (if possible) calling of ssh-agent (unless we want WONTFIX, but that's
IMHO not correct, because this really looks like our bug). Therefore, I think,
that this bug belongs to you. Feel free to reASSIGN to somebody better.

see for more info FC bug#164869.

additionally, rhel3 do not have setuid ssh-agent . rhel4 and above do.

proposed patch

A wrapper script to start desktop session and saving LD_LIBRARY_PATH .
To apply the patch

cd /
touch etc/X11/xinit/xinitrc-ssh
cat /path/to/xinitrc_ld_library_path_rhel5.patch| patch -p0
chmod a+x /etc/X11/xinit/xinitrc-ssh

log-out and login. This should resolve the issue.
Comment 3 ritz 2007-02-26 12:14:48 UTC 
works for the customer.
Comment 4 ritz 2007-02-26 12:22:51 UTC 
additional note:
kde does not export bashrc during login. checking this up.
workaround is to use profile.d , or $HOME/.xsession
Comment 5 Ray Strode [halfline] 2007-02-27 23:11:14 UTC 
We should probably just change ssh-agent to use its alternate syntax instead of
doing the pass through way we do now.
Comment 6 ritz 2007-08-10 19:35:24 UTC 
patch from bugzilla #164869 [1]  helps.

Devel ack. Fastrack is fine with me.
