Introduction

Automount is the modern way to mount directories over a network. It is far easier to manage and is more economic in bandwidth. In this howto, autofs will be configured through an LDAP directory: in that way, we have a centralised configuration and make maximum use of the LDAP that has been setup. Great, isn't it?

Installation

First of all, automount is composed of two parts: a kernel module and user land utilities. Kernels in modern GNU/Linux distributions are compiled with support for automount. You just have to install the 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 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 kinds of entries:

entry that defines the mountpoint
entry that defines the directory under a mountpoint

Here is an example of LDAP entries based on the 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: ou=auto.home,ou=automount,ou=admin,dc=example,dc=com
ou: auto.home
objectClass: top
objectClass organizationalUnit

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 the LDAP map to the automount entry of /etc/nsswitch.conf. Edit your /etc/nsswitch.conf and add the line:

automount:      files ldap

The package ldap-utils has to be configured. Edit /etc/ldap/ldap.conf:

BASE    dc=example,dc=com
URI     ldap://ldap.example.com

Launch

autofs looks in the LDAP directory for the automountMap. You just have to launch autofs:

sudo /etc/init.d/autofs start

Test

Just check with a mount that automount has been started correctly:

mount | grep automount
automount(pid5058) on /home type autofs (rw,fd=4,pgrp=5058,minproto=2,maxproto=4)
