Description Gene Czarcinski 2004-03-29 14:25:06 UTC

Description of problem:
I have two regular (non root) users defined and an admin user too.  I
am loged in as the admin user.  If I try to su to the regular user
   su - genec
I am prompted to see if I want to change the security context (defualt
=y) but nothing entered seems to work.  There are no alternate
contexts defined for this user.

If I use ssh to try and login from another system .. I get in, no prompts.

Per Dan Walsh:

"The ssh behavior is currect.  The only time you should get prompted
for security contexts is if the user has the ability to have more than
one security context."

I had a similar problem, but perhaps worse (you don't mention whether
you were able to log in directly as the two regular users).  

This was immediately after a fresh install of Core2 Test2 onto a clean
partition.  After doing the cd install (with permissive selinux chosen
from the firewall screen) and rebooting, during "first boot"
initialization gui dialogs I set up a new user account.  However when
I went to log in as that user I was unable to.  Investigation revealed
the user hadn't been created.  No entry in /etc/passwd, no directory
in /home.

So I logged in as root and used the gui User admin tool to create the
new user.  This time the user was created.

On trying to log in as that user I would get:

via gdm: popup saying something like "executable context not allowed",
click ok bombs me back to gdm.

via console: same message you received (change security context, tried
entering user_r/user_t, which wasn't accepted).

via su (from root): same security context message

didn't try ssh.

Running:

fixfiles relabel
reboot

fixed things for me.

Please try with latest Fedora Core.

I don't see such problems with FC3 and targeted selinux policy.
