1.8.2 Implementing /home/ with automount, NFS and LDAP
It is convenient for system administrators and developers to keep their work in their own
home directory under /home/. With tens or even hundreds of Linux systems you would
normally have tens or even hundreds of home directories. The size requirement for this file
system would vary widely from server to server.
It is easier to manage a single large /home/ directory that “follows users around” This can be
implemented with the automount service, NFS and LDAP. LDAP allows for central
authentication and authorization of users and resources. Following is a block diagram:

For details on how to implement this, see the IBM Redbook z/VM and Linux on IBM System z
