How to setup a LDAP Server

Wed, Jul 1, 2009

Installation

We need to install the ldap packages

apt-get install slapd ldap-utils migrationtools

Answer the questions and then use dpkg to reconfigure slapd for more options

dpkg-reconfigure slapd

Omit OpenLDAP server configuration? ... No
DNS domain name: ... home.local
Name of your organization: ... home
Admin Password: some-really-strong-password
Confirm Password: some-really-strong-password
OK
BDB
Do you want your database to be removed when slapd is purged? ... No
Move old database? ... Yes
Allow LDAPv2 Protocol? ... No

Check that the ldap server is now running
```
ldapsearch -x -b dc=home,dc=local
```
If you get this error
```
ldap_bind: Can't contact LDAP server (-1)
```
Its likely the daemon isn't running so start it
```
/etc/init.d/slapd start
```

Populating the Database

We can use migration tools to export all of our users and groups into the LDAP db switch into the migrations tools directory

cd /usr/share/migrationtools/

Edit the migrations tools config file

nano migrate_common.ph

and replace the following

DEFAULT_MAIL_DOMAIN = "home.local";
DEFAULT_BASE = "dc=home,dc=local";

Export the users and groups

./migrate_group.pl /etc/group /tmp/group.ldif
./migrate_passwd.pl /etc/passwd /tmp/passwd.ldif

Migrate tools doesn't create the group and people nodes therefore we need to create them open /tmp/nodes.ldif

nano /tmp/nodes.ldif

and paste in the following

dn: ou=People, dc=home, dc=local
ou: People
objectclass: organizationalUnit

dn: ou=Group, dc=home, dc=local
ou: Group
objectclass: organizationalUnit

Finally we need to import the entries into our LDAP database

ldapadd -x -W -D "cn=admin,dc=home,dc=local" -f /tmp/nodes.ldif
ldapadd -x -W -D "cn=admin,dc=home,dc=local" -f /tmp/group.ldif
ldapadd -x -W -D "cn=admin,dc=home,dc=local" -f /tmp/passwd.ldif

That is your LDAP server setup In this tutorial it will show you how to configure your LDAP Clients
