KB-10571: RHEL 5.x SELinux module incompatibility

25 June,18 at 10:56 AM

Applies to: Centrify Infrastructure Services 2016.1 above on RHEL 5.x

Description:
On RHEL 5.x server, Selinux is in enforcing mode. The SELinux reported issue with different processes like sshd and it can be found in audit.log that the process was denied. 
 
Root cause:
An older version of SELinux policy module is used by RHEL 5.x. However, since RHEL 6.x, there is a newer version introduced and we are making use of the newer version of SELinux module instead. Therefore, there will be incompatibility issue on RHEL 5.x with SELinux enforced with Centrify 2016.1 or later release.
 
Workaround:
Use below command to update SELinux policy to allow sshd or any other process being rejected in SELinux which can be found in audit.log:
# grep sshd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Resolution:
N/A. It is because RHEL 5 was deprecated in RedHat and the new module was introduced.
