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 System in the UDM 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 of the CentOS System to the variable to

ldap/acl/read/ips

on your DC Master and Backups.

CentOS Installation

During the Installation you should choose one of your UCS Domain Controllers as the ntp Timeserver. Additional you should configure the hostname for the Server and not rely 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 DC for DC. The base DN can be found on a DC using the command

ucr get ldap/base

Afterwards you should be able to log into your CentOS System
