Install LDAP server

  • With Ubuntu or Debian, install package slapd and ldap.
  • With Windows, you can use the install program of OpenLDAP.

Once this is done, you have an empty LDAP server launched as a service.

Setup server

For Ubuntu, see page http://doc.ubuntu-fr.org/openldap-server

Otherwise the DN root, user and password to connect may be available into:

  • file slapd.conf. Port may also be into this file, if not, it is default port value: 389.
  • file olcDatabase={1}hdb.ldif. Entry with login/pass are olcRootDN and olcRootPW.

Stop the service

Modify file slapd.conf to use your domain name (replace all dc=my-domain,dc=com by value of your choice).

Modify file slapd.conf also to add includes of schemas you will need to declare your LDAP objects.

include		./schema/core.schema
include		./schema/cosine.schema
include		./schema/inetorgperson.schema
include		./schema/nis.schema

or add shemas with

sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/cosine.ldif
sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/nis.ldif
sudo ldapadd -Y EXTERNAL -H ldapi:/// -f /etc/ldap/schema/inetorgperson.ldif

Restart the service.

Test server

With a LDAP browser like JXplorer, you can try to connect to your LDAP server using the admin LDAP user. Credentials by default are:

  • Server: Localhost
  • Port: 389
  • User: cn=admin,dc=example,dc=com or cn=Manager,dc=example,dc=com or cn=admin,dc=nodomain
  • Password: secret
  • Base DN (optionnel): keep empty or set dc=mydomain,dc=com

Create your LDAP tree

Next step is to define information to store into your LDAP.

Create a file init.ldif with your organization. For example (take care to keep empty line between each block. With some LDAP, you may also need to create several files for each block):

# Organization
# 2 new lines or end of file after field description
dn: dc=mydomain,dc=com
objectclass: dcObject
objectclass: organization
dc: mydomain
o: Label of mydomain
description: Description for mydomain container
 
 
# Setting up container for Users OU
# 2 new lines or end of file after field description
dn: ou=mypeople,dc=mydomain,dc=com
objectclass: top
objectclass: organizationalUnit
ou: mypeople
description: Description for mypeople container
 
 
# Setting up container for groups
# 2 new lines or end of file after field description
dn: ou=mygroups,dc=mydomain,dc=com
objectclass: top
objectclass: organizationalUnit
ou: mygroups
description: Description for mygroups container

Execute file using the LDAP admin user:

ldapadd -f init.ldif -D "cn=admin,dc=mydomain,dc=com" -w secret

Create few users

Create a file inituser.ldif with your organization. For example (take care to keep empty line between each block):

# Some User
dn: sn=someuser,ou=mypeople,dc=nodomain
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
cn: Some User
sn: someuser
mail: someuser@nodomain
userPassword: {SSHA}hnP4gNK7SbgsAW3eTZYf23a4R7Ob19l2

Use slappasswd -s passwordtocrypt to generate a password.

Troubleshooting

With Windows, it server is stop suddenly, restart of OpenLDAP may fails with error Program version x.y doesn't match environment version

To confirm problem, go onto DOS under directory data of OpenLDAP and launch command

..\db_stat -e

If message is the one described, launch repare of base with

..\db_recover

Server should be able to start again.
