Introduction
Automount is the modern way to mount directories over a network. It is far much easier to manage and are more economic in bandwith.
In this howto, autofs will be configured through LDAP directory: in that way, we have a centralised configuration and we use a maximum the LDAP that has been setup. Great, isn't it ?
Installation
First of all, automount is composed of two parts : kernel module and user land utilities. Kernels in modern GNU/Linux distributions are compiled with support for automount. You just have to install user land utilities : install the following packages autofs-ldap ldap-utils (see InstallingSoftware).
If you plan to only use flat files configuration, you do not need to install the autofs-ldap package: installation is described in UbuntuHelp:Autofs howto.
Configuration
Configuring LDAP automount consists of several parts:
- configure openldap server to load the autofs-ldap schema
- entering LDAP entries for defining mountpoints
- entering LDAP entries for defining directories
- defining on the client to use LDAP for automount configuration
On the server
Tell the slapd daemon to load /etc/ldap/schema/autofs-ldap.schema:
sudo nano /etc/ldap/slapd.conf
and add the line
#Schema and objectClass definitions include /etc/ldap/schema/autofs.schema
The autofs.schema line must be inserted after core.schema and cosine.schema
Finally restart the slapd service:
sudo /etc/init.d/slapd restart
Populating LDAP
In the LDAP directory, you have to enter two kind of entries:
- entries that defines the mountpoint
- entries that defines the directory under a mountpoint
Here is an example of LDAP entries based on the UbuntuHelp:OpenLDAPServer installation.
dn: ou=admin,dc=example,dc=com ou: admin objectClass: top objectClass: organizationalUnit dn: ou=automount,ou=admin,dc=example,dc=com ou: automount objectClass: top objectClass: organizationalUnit dn: ou=auto.master,ou=automount,ou=admin,dc=example,dc=com ou: auto.master objectClass: top objectClass: automountMap dn: cn=/home,ou=auto.master,ou=automount,ou=admin,dc=example,dc=com cn: /home objectClass: top objectClass: automount automountInformation: ldap:ou=auto.home,ou=automount,ou=admin,dc=example,dc=com --timeout=60 --ghost dn: cn=lionel,ou=auto.home,ou=automount,ou=admin,dc=example,dc=com cn: lionel objectClass: top objectClass: automount automountInformation: -fstype=nfs,rw,hard,intr,nodev,exec,nosuid,rsize=8192,wsize=8192 nfs.example.com:/export/home/lionel
On the client
On the client, you only have to add LDAP map to the automount entry of /etc/nsswitch.conf. Edit you /etc/nsswitch.conf and add the line:
automount: files ldap
The package ldap-utils have to be configured. Edit /etc/ldap/ldap.conf:
BASE dc=example,dc=com URI ldap://ldap.example.com
Launch
autofs look in the LDAP directory for automountMap. You just have to launch autofs:
sudo /etc/init.d/autofs start
Test
Just check with a mount that automount is well launched:
mount | grep automount automount(pid5058) on /home type autofs (rw,fd=4,pgrp=5058,minproto=2,maxproto=4)
