su invalidly prompts for security context
Last modified: 2007-11-30 17:10:39 EST
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
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.
fixed things for me.
Please try with latest Fedora Core.
I don't see such problems with FC3 and targeted selinux policy.
