Description SEKINE Tatsuo 2005-05-03 09:53:10 EDT
From Bugzilla Helper:
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
sessions, i.e.:
  fooo@bar$ su
  (input pass)
  root@bar# su fooo
  fooo@bar$ su
  ** freeze for 20 seconds **

While the terminal was freezing, I could observe the following process via
another terminal:
  /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):


How reproducible:
Always

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.
