Through ssh/GUI:

system_u:system_r:unconfined_t:SystemLow-SystemHigh
Now that I write this, I notice that the user and role have changed as
well. I also notice this in the audit log:
type=USER_ROLE_CHANGE msg=audit(1184777815.107:4063): user pid=5517
uid=0 auid=500 subj=system_u:system_r:local_login_t:s0-s0:c0.c1023
msg='pam: default-context=user_u:system_r:unconfined_t:s0:c1 selected-
context=?: exe="/bin/login" (hostname=?, addr=?, terminal=tty1
res=success)'
This is running on RHEL 5.0.0 targeted policy. Any clues?
Thanks,
Forrest

This looks like a bug.
But a lot of fixes were added for 5.1 for MLS policy and this might have
been one of them. Since this is pretty fundamental to mls.
A prerelease of the mls packages is available at
http://people.redhat.com/sgrubb/files/lspp/
Yes, that fixed the problem. I pointed yum to Steve's repo and
installed all the updates. Now I get this context:
user_u:system_r:unconfined_t::admin1
Interesting that it has :: before admin1. I assume that this tells us
that admin1 is defined as both a security level and a category.
Although this doesn't hold true for root:
root:system_r:unconfined_t:-SystemHigh
Why does root have -SystemHigh (why the dash)? Turning off mcstrans
shows that it is s0-s0:c0.c1023, so how is that translated to -
SystemHigh, and why doesn't it have :: ?
Thanks,
Forrest
This looks like a translation problem. You have s0->"" So this is really
s0:admin1
s0-SystemHigh
