User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050328 Fedora/1.7.6-1.2.5
Description of problem:
When I use a terminal(e.g. xterm) on X, I have to wait about 20 seconds
after I input "su" in odd situation.
The "odd" situation means that executing su 3 times without ending each
root@bar# su fooo
** freeze for 20 seconds **
While the terminal was freezing, I could observe the following process via
/usr/X11R6/bin/xauth -f /root/.xauthXXXXXX nlist :0.0
In the same situation without X, there is no freezing, so pam_xauth may
cause this problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. open terminal on X
2. type su by user foo
3. type su by user root
4. type su by user foo
Actual Results: You have to wait for a while after password input.
Expected Results: You don't need wait after that.
Actually, the extent of this bug is really small.
