Description Steve Grubb 2005-04-14 22:55:58 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050227 Firefox/1.0.1 Fedora/1.0.1-2

Description of problem:
The first issue is that su does not set the pam tty variable. This is needed 
for auditing among other things.

Next, if there was a problem with init groups, session close must be called 
since session open can mount drives.

The pam credentials should not be set in the child since the parent will need 
to dispose of credentials later.

If there is a fork error, pam credentials need to be deleted and the session 
closed.

The parent needs to delete the pam credentials before it ends pam.

Version-Release number of selected component (if applicable):
coreutils-5.2.1-44

How reproducible:
Always

Steps to Reproduce:
1. install the latest pam
2. do a su - root
3. look in the audit log what tty

the other items are based on code review  

Actual Results:  terminal=?

Expected Results:  terminal=pts/5
