Apple Address Book Support
Kerio MailServer supports Apple Address Book, the standard directory of Mac OS X. This sup-
port includes the option of searching forcontacts in the Kerio MailServer’s LDAP database and,
since Mac OS X 10.3, also of bi-directional synchronization of contacts with Kerio MailServer’s
user accounts .
Kerio MailServer supports Apple Address Book for the following versions:
•Mac OS X 10.2 Jaguar
•Mac OS X 10.3 Panther
•Mac OS X 10.4 Tiger
•Mac OS X 10.5 Leopard
Setting options are different for these versions — therefore, they will be focused in separate
sections:

12.1 Apple Address Book pro Mac OS X 10.2 Jaguar

In this version, Kerio MailServer supports search in the Kerio MailServer LDAP database. The
option of search in LDAP database allows automatic checkfor email addresses during message
composition in Apple Mail. All addresses included in the LDAP database (addresses of all Kerio
MailServer accounts) are checked.
Apple Address Book parameters can be set under Address Book →Preferences:
1. Switch to the LDAP tab
2. Specify the Server item with the DNS name or the IP address of the host where Kerio
MailServer is running and the LDAP port for the server.
SSL-secured LDAP can be used for the traffic. However, in such a case it is necessary to au-
thenticate by a trustworthy certificate (for details, refer to chapter 10.7). Apple Address Book
connects toKerio MailServer by encrypted connection using the LDAP Start TLS extension. It
is necessary to follow these steps when setting the encrypted communication on the Address
Book →Preferences →LDAP tab:
1. enable the Use SSL option,
2. change the default port 636 to the port used in Kerio MailServer for the non-secured LDAP
service (typically port 389). In case that you want to use SSL-secured connection to the
server (Use SSL), a trustworthy certificate installed is required.
