Description Kaushik Banerjee 2012-10-16 10:09:07 EDT
Description of problem:
SELinux is preventing /usr/sbin/sshd from read access on the file /var/lib/sss/mc/passwd

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Setup sssd to perform a auth.
2. Try to auth as a user. Auth succeeds, but AVC appears.
Actual results:
On performing a auth, audit.log shows:

type=SYSCALL msg=audit(1350289695.662:350): arch=c000003e syscall=2 success=no exit=-13 a0=7ffa6e552b10 a1=80000 a2=0 a3=17 items=0 ppid=5510 pid=20718 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="sshd" exe="/usr/sbin/sshd" subj=system_u:system_r:sshd_t:s0-s0:c0.c1023 key=(null)
type=AVC msg=audit(1350289695.662:350): avc:  denied  { read } for  pid=20718 comm="sshd" name="passwd" dev=dm-0 ino=1713209 scontext=system_u:system_r:sshd_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:sssd_var_lib_t:s0 tclass=file

Expected results:
AVC should not appear on performing a auth.

Additional info:
The following steps solves the issue:
# semanage fcontext -a -t sssd_public_t "/var/lib/sss/mc(/.*)?"
# restorecon -R -v /var/lib/sss/mc/

We need to backport fixes from Fedora.
