KB-1694: How to integrate RHN Satellite login with DirectControl to accept AD user authentication?

Centrify DirectAudit ,   Centrify DirectControl ,   Centrify Identity Service, Mac Edition ,  

12 April,16 at 11:12 AM

Applies to: All versions of Centrify DirectControl for UNIX/Linux
 
Question:
 
RHN Satellite supports network-based authentication systems via Pluggable Authentication Modules (PAM). PAM is a suite of libraries that helps system administrators to integrate the Satellite with a centralized authentication mechanism, thus eliminating the need for remembering multiple passwords.
 
RHN Satellite supports LDAP, Kerberos, and other network-based authentication systems via PAM. It is possible to enable PAM authentication for a RedHat Satellite Server. Ordinary ssh and local authentication works, however the satellite server does not allow a login even when the Centrify username and password are correct.
 
Does Centrify provide an example configuration that can show how to integrate RHN Satellite application logins with the Centrify DirectControl PAM modules? 
 
Answer:
 
One is advised to upgrade to Centrify DirectControl 4.4.1 or above as there was a known issue where we have a restriction on PAM account management for non-root users in versions earlier than DirectControl 4.4.0.
 
After the upgrade, please follow these steps:
 
1) Set up a PAM service file (usually /etc/pam.d/rhn-satellite) and have the Satellite use it by adding the following line to /etc/rhn/rhn.conf:
 
pam_auth_service = rhn-satellite

This assumes the PAM service file is named rhn-satellite.
 
2) As an example, for a Red Hat Enterprise Linux 5 i386 system, to authenticate against Active Directory one could put the following in /etc/pam.d/rhn-satellite. Please note that these are standard Centrify PAM directives. 
 
#%PAM-1.0
auth       sufficient     pam_centrifydc.so
auth       requisite      pam_centrifydc.so deny
account    sufficient     pam_centrifydc.so
account    requisite      pam_centrifydc.so deny
session    required       pam_centrifydc.so homedir
password   sufficient     pam_centrifydc.so try_first_pass
password   requisite      pam_centrifydc.so deny
 
3) For the remaining steps, please follow the installation guide below (choose the appropriate version) :
