Produktlogo UCS Version 3.0

This guide describes how to include CentOS 6.2 in an UCS 3.0 domain. It only shows the diverging points from the standard CentOS installation.

Inclusion in the Management System

To include the CentOS system into the UCS management system, add it as a member server. This ensures that the proper accounts will be added for the client.

Further it is necessary to add the IP address of the CentOS System to the variable to

ldap/acl/read/ips

on your DC Master and Backups.

CentOS Installation

During the installation one of UCS domain controllers should be chosen as the ntp time server. Additionally, the hostname for the system should be configured manually and not be relied on the DHCP offered one.

Authentication Configuration

First the needed PAM modules need to be installed:

yum install openldap openldap-clients nss_ldap krb5-libs krb5-workstation

Afterwards LDAP and Kerberos need to be enabled:

authconfig --enablekrb5 --krb5kdc=<DC> --krb5realm=<REALM> --krb5adminserver=<DC> --enablecache --update
authconfig --enableldapauth --ldapserver=<DC>:7389 --ldapbasedn=<base DN> --disableldaptls \
--ldaploadcacert=https://<DC Master>/ucs-root-ca.crt --update

thereby you can use any UCS domain controller for the domain controller. The base DN can be found on a UCS domain controller using the command

ucr get ldap/base

Afterwards you should be able to log into your CentOS System.
