Description Jeremy Katz 2007-09-20 15:01:44 EDT
Following Dan's instructions for setting up pam_namespace with an xguest user, I
can't login as xguest.

avc errors are about xdm_t creating files labeled etc_t when trying to copy the
/etc/skel bits, but it shouldn't be trying to create them as etc_t anyway I
don't think.
Comment 1 Tomas Mraz 2007-09-20 15:40:09 EDT
Can you try to modify /etc/security/namespace.init so it contains 
cp -aT --no-preserve=context .....
instead of
cp -aT .....

Does it help?
Comment 2 Tomas Mraz 2007-09-20 15:40:42 EDT
If not, what are all the AVCs?
Comment 3 Jeremy Katz 2007-09-20 15:53:30 EDT
That helps somewhat...

I'll add the --no-preserve=context to the next pam build however the rest has to
be fixed in the policy.
Comment 5 Daniel Walsh 2007-09-21 10:48:15 EDT
Tomas the patch I sent you this morning fixes these.
