Description Patrik Kis 2012-06-20 09:07:18 EDT
Description of problem:
ANC denial prevents freeradius2 communicate with postgresql on RHEL5, while on RHEL6 it is working out of the box.

Version-Release number of selected component (if applicable):
# rpm -q freeradius2 postgresql selinux-policy
freeradius2-2.1.12-3.el5
postgresql-8.1.23-1.el5_7.3
selinux-policy-2.4.6-327.el5

How reproducible:
always

Steps to Reproduce:
1. run test /CoreOS/freeradius/Sanity/postgresql-auth-test
2. When radiusd start the following AVC appears and the test fails:
type=AVC msg=audit(1340196443.406:1177): avc:  denied  { name_connect } for  pid=22893 comm="radiusd" dest=5432 scontext=root:system_r:radiusd_t:s0 tcontext=system_u:object_r:postgresql_port_t:s0 tclass=tcp_socket
  
Actual results:
AVC denial

Expected results:
no AVC denial

Additional info:
It seems there are missing policies on RHEL5.
This test was newer launched on RHEL5; it was only now made ready for RHEL5 that's the reason why this error was hidden so far.
