HOWTO : OpenLDAP 2.4 NFSv4 Automount Map Repository on CentOS 6.2

We continue our OpenLDAP 2.4 series with goal number 6.

1. Install OpenLDAP 2.4.
2. Configure Transport Layer Security (TLS).
3. Manage users and groups in OpenLDAP.
4. Configure pam_ldap to authenticate users via OpenLDAP.
5. Use OpenLDAP as sudo's configuration repository.
6. Use OpenLDAP as automount map repository for autofs.
7. Use OpenLDAP as NFS netgroup repository again for autofs.
8. Use OpenLDAP as the Kerberos principal repository.
9. Setup OpenLDAP backup and recovery.
10. Setup OpenLDAP replication.

In this document, we will learn how to setup an NFS server along with an NFS client which runs autofs(5) version 5. This daemon will fetch his automount maps from our OpenLDAP 2.4 server. The client will then be configured to mount users home directories from the NFS server. All OpenLDAP users DN will be modified to reflect this change. We will also create a central NFS software repository.
