Description of problem:
For some reason sudo doesn't seem to function for me anymore.  My
account, "smj", is in the /etc/sudoers file, and this hasn't changed
since I upgraded from test2 to test 3.

What has changed is that I can't seem to do anything with sudo since I
upgraded the system.

Version-Release number of selected component (if applicable):
sudo-1.6.7p5-26

How reproducible:
Always

Steps to Reproduce:
1.  Login as a user in the /etc/sudoers file that has ALL=(ALL) ALL
access.
2.  Type sudo followed by any command of your choice.
3.  Enter your password, if necessary.
    

Actual Results:  The prompt returns the following:
sudo: unable to exec /usr/sbin/sesh: Permission denied

Within /var/log/messages, the following is returned:
Apr 26 18:15:25 shekhina kernel: audit(1083017725.655:0): avc:  denied
 { execute_no_trans } for  pid=1965 exe=/usr/bin/sudo
path=/usr/sbin/sesh dev=dm-2 ino=622886
scontext=user_u:user_r:user_sudo_t
tcontext=system_u:object_r:shell_exec_t tclass=file

Expected Results:  The command will be executed with the permissions
as granted in /etc/sudoers.

Additional info:

I'm still pretty new to Fedora Core 2 Test 3 and selinux.  The account
"smj" authenticates via NIS to a server running Debian 3.0.  This was
not a problem during Fedora Core 2 Test 2, so something in the upgrade
done this weekend changed sudo's behavior.

The line in /var/log/messages makes me think that it is related to the
selinux policy for the system.  If I'm using something incorrectly,
then forgive me, but it doesn't seem to work as advertised.
