LDAPBook is our 2nd generation tool. We took what we learned from service and applied it to our new LDAPBook tool that is now accessible over at

Server List

Your LDAP client can query any one of these LDAPBook servers. Pick one closest to you for fastest performance.

  • (offline for now)

All servers accept SSL (port 636) connections.

Client Comparison

Unfortunately, most of the mail clients only allow searching and not Browsing. Browsing allows for listing all your contacts from the LDAP server when the Address Book is opened. Instead, these clients only allow Searching of contacts.

Client LDAP support Browsing
Thunderbird Yes No*
Evolution Yes Yes
Mac OS AB Yes No
Outlook Express Yes No
Outlook Yes No

*Thunderbird has an extension called Contacts Sidebar that allows Browsing.

Client Configuration

Here are generic instructions for configuring your LDAP client (address book) to connect to our LDAP server.

  • Ensure the Bind and Base/Search DN are: uid=<username>, ou=People,
  • SSL is selected, port 636
  • Host or server name should be one of the above

Replace <username> with your own user name, e.g.: uid=surf, ou=People, You can find specific instructions below.



Here are some VoIP (hard and soft) phones that support LDAP protocol. Please note: We have not tested these and you should be sure they work before plunging ahead and purchasing them for use with our LDAPBook. You'll of course need a SIP provider for this.

Hard/Desk Phones
