Applies to all Email Security Gateways using Kerio MailServer 6.0 for LDAP lookups.

Common syntax used for Kerio MailServer 6.0:
  • Port: 389 (636 for secure LDAP)
  • Bind DN: (Kerio LDAP server needs full email addresses for queries) 
  • LDAP Filter: ( (mail=${recipient_email})) 
  • LDAP Search Base:,fn=ContactRoot (or you can leave this blank)
  • LDAP UID: cn
  • LDAP Primary Email Attribute: mail

Filter setup to work with aliases:
( (mail=${recipient_email})

Also:  The UID used can vary.. recommended sAMAccountName or cn
