Lightweight Directory Access Protocol (LDAP) is an open standard protocol that is commonly used to communicate with directory servers. Common examples include Microsoft Active Directory, Lotus Domino, SunOne/iPlanet Directory Server and Novell eDirectory. To learn more, visit .

Go to Basic Configuration > LDAP Servers to view or configure one or more connections to your organization’s LDAP server. ArcTitan can use LDAP in the following ways:

  • To assist when validating a user login

  • To expand email addresses in non-enveloped emails

  • To provide user account lists in the user directory, mailbox reader and folder replication tabs.

Follow the steps below to add a new LDAP connection.
