Synchronizing with LDAP

ESET Secure Authentication supports synchronization with LDAP.


An administrator can synchronize either the entire AD domain or select only a specific OU subtree of the AD domain.

In the case of a Windows domain, only one OU subtree can be synchronized per AD domain (directory service) because the entire AD GUID becomes the created realm's ID. If the administrator tries to synchronize another OU subtree of that AD (Windows domain), the "Realm '<ID>' already exists" error message will display.

Sample LDAP Server Path to synchronize an OU subtree of "esa.local" AD domain (Windows domain):



When synchronizing a different directory type, the entire Server LDAP Path becomes the created realm's ID.

1.Access ESA Web Console and click Users.

2.Next to Realms, click icon_add-or-create, select Create Synchronized Realm.

3.Type the address of your LDAP server, select the applicable LDAP server type from the Sync Server type drop-down menu, and type your LDAP username and password.

4.If this is a one time import, leave the Sync interval intact. Otherwise, select the applicable synchronization interval.

5.Select the check box next to Run immediately and click Save.



When your ESA instance is synchronized with LDAP, to synchronize it again manually:

1.In the Realms section, select the saved and synchronized LDAP server.

2.Click the gear icon icon_settings_inline and then click Synchronize Now.
