An OpenLDAP addressbook/directory for Thunderbird

This guide will help you setting up an LDAP directory under RHEL 4/CentOS 4 systems, 100 % compatible with Mozilla Thunderbird 1.5. Management of the LDAP directory will be done with phpLdapAdmin.

1. Install the needed packages # yum install openldap-servers openldap-clients

2. Download the LDAP schema for Thunderbird # wget -O /etc/openldap/schema/thunderbird.schema

3. Create the directory tree in which the database will be stored # mkdir /var/lib/ldap/local

4. Change ownership # chown ldap:ldap /var/lib/ldap/local

5. Make sure LDAP will start at boot # chkconfig --level 345 ldap on

6. open tcp port 389 under iptables `# iptables -A INPUT -p tcp –dport 389 -j ACCEPT

7. Make a backup of the default config # mv /etc/openldap/slapd.conf /etc/openldap/slapd.conf.bak

  1. Create and edit /etc/openldap/slapd.conf :

    include /etc/openldap/schema/core.schema include /etc/openldap/schema/cosine.schema include /etc/openldap/schema/inetorgperson.schema #include /etc/openldap/schema/nis.schema include /etc/openldap/schema/thunderbird.schema

    bind_v2 will allow compatibility with older Thunderbird clients (tested under v0.4 & v0.5)

    allow bind_v2

    pidfile /var/run/ argsfile /var/run/slapd.args

    database bdb suffix “dc=domain,dc=be” rootdn “cn=AddressManager,dc=domain,dc=be” rootpw secret

    directory /var/lib/ldap/local

    index objectClass eq,pres index ou,cn,mail,surname,givenname eq,pres,sub #index uidNumber,gidNumber,loginShell eq,pres #index uid,memberUid eq,pres,sub #index nisMapName,nisMapEntry eq,pres,sub

  2. Start the ldap service : [root@server](1034)# service ldap start Checking configuration files for : config file testing succeeded Starting slapd: [ OK ]

  3. Make sure ldap is running (IMPORTANT : if slapd crashes, you’d still get an OK when starting the service) : [root@server](1036)# service ldap status slapd (pid 2299) is running...

  4. Create directory_def.ldif (directory structure) : dn: dc=domain,dc=be objectclass: top objectclass: dcObject objectclass: organization dc: domain o: Name of your company

  5. Create directory.ldif (directory data) : dn: cn=John Doe,dc=domain,dc=be objectclass: top objectclass: person objectclass: organizationalPerson objectclass: inetOrgPerson givenName: John sn: Doe cn: John Doe mail:

Contacts should be separated by a blank line

  1. Inject the directory structure :

    ldapadd -xv -D “cn=AddressManager,dc=domain,dc=be” -f directory_def.ldif -W

    ldap_initialize( ) Enter LDAP Password: xxxxxx add objectclass: top dcObject organization add dc: domain add o: Name of your company adding new entry “dc=domain,dc=be” modify complete

  2. Inject the data into the directory : ldapadd -xv -D "cn=AddressManager,dc=domain,dc=be" -f directory.ldif -W

  3. Make sure data have been correctly injected :

    ldapsearch -x -b “dc=domain,dc=be” “(objectclass=*)”

    extended LDIF


    base with scope sub

    filter: (objectclass=*)

    requesting: ALL

    dn: dc=domain,dc=be objectClass: top objectClass: dcObject objectClass: organization dc: domain o: Name of your company

    John Doe,

    dn: cn=John Doe,dc=domain,dc=be objectClass: top objectClass: person objectClass: organizationalPerson objectClass: inetOrgPerson givenName: John sn: Doe cn: John Doe mail:

  4. Add the ldap addressbook server into Thunderbird :

For some reason, setting LDAP autocompletion into the general configuration did not work. I had to add the LDAP autocompletion into the account settings

For more info :

For : Name : domain directory Hostname : Base DN : dc=domain,dc=be

  1. Install phpldapadmin


$ldapservers->SetValue($i,'server','name','Thunderbird LDAP Server'); $ldapservers->SetValue($i,'server','host',''); $ldapservers->SetValue($i,'server','port','389'); $ldapservers->SetValue($i,'server','base',array('dc=domain,dc=be')); $ldapservers->SetValue($i,'server','auth_type','config'); $ldapservers->SetValue($i,'login','dn','cn=AddressManager,dc=domain,dc=be'); $ldapservers->SetValue($i,'login','pass','secret');

Connect to You should be able to access your LDAP database, please note that this config is not the most secure scheme, you should set a password to access this directory

More info :

Thunderbird can only read into LDAP directories, not write :
