Configure the Connection settings to Lucy

  • Server - Domain name of Lucy's Admin console or IP address of Lucy server (e.g.,, A custom port can be specified after the colon (e.g.
  • Username and Password - Administrator login credentials

:!: Click on "Test connection" to validate the credentials.

When finished, click Next to create a new recipient group or select an existing one.

Configure the Connection settings to Active Directory LDAP Server

Next, you need to configure the connection between the tool and your Active Directory by entering the following information:

  • Host - domain name or IP address of the domain controller (e.g., ldap.domain.local)
  • Port - (default: 389 or 636) or LDAP port. If "Use Global Catalog" and "Use SSL" are enabled you should use the ports 3268 and 3269
  • Username and Password - current user login credentials or a specific set of user credentials
  • Use SSL - enable secure connection
  • Use Global Catalog - enable to find objects in an Active Directory domain tree, given one or more attributes of the target object
  • Base DN - root node under which all of your user and group objects are located
  • Auth type - (default: Negotiate) method which is used to authenticate the LDAP connection

When finished, click Next to select Active Directory groups.

Select the Active Directory groups to export

Once your Active Directory settings are configured, select the Active Directory groups from which users will be imported into Lucy.

There are two options:

  • Define filter for a single group - allows to select several AD groups to be imported into one Lucy's recipients group.
  • Select multiple User Groups - allows to select several AD groups to import each into its own recipients group in Lucy.

If an option Define filter for a single group is used, you may either select an existing group or create a new recipient group using the buttons "New recipient group" and "Delete recipient group".

:!: Please keep in mind that deleting any recipient groups using the tool may affect the statistics in your campaigns. Deletion cannot be undone.

You can also use Search filter to find the specific group.

At this point select an LDAP group for synchronization or use Filter to build your own query.

You may use regular Active Directory search filters, for example: (|(objectClass=inetOrgPerson)(objectClass=user)). See Microsoft Documentation for more info.

Click on "Test filter" to see the first 10 users received from Active Directory.

When you have selected the Active Directory group, click Next to see the overall settings.

Multiple group sync

Multiple group synchronization can be proceeded with the latest version of the LDAP synchronization tool. Selecting multiple AD groups will add separate recipient groups to Lucy.

Check Active Directory groups and press Add

:!: Attention! A new recipient group will be created in Lucy with the same name as the user group. If the recipient group already exists, new recipients will be added to it. Please note that Lucy will send emails for any new recipients added to the running campaign.

Review the settings

Verify the settings and click Next when you are ready to start the import.


Once the synchronization process is finished, you can observe the debug log.

You can save the import settings to a file by clicking the "Save config" button. The file can be used the next time you import recipients. To do this, select the configuration file at the first step of the synchronization wizard.

Click on "Register service" to install the tool as a Windows service. When running as a Windows service, the tool performs the sync every 10 minutes (:!: not configurable in the current version).

To remove the service, run the tool once again and click "Remove service" on the Lucy connection settings step.

Default actions

By default, the tool performs the following actions when specific events happen to users in your Active Directory (the actions are not configurable in the current version):

  • When a new user in Active Directory is detected: Automatically create recipient in Lucy and add it to the selected recipient group.
  • When a user in Active Directory is deleted: Automatically delete recipient from Lucy
  • When a user in Active Directory is removed from group in filter: Automatically delete recipient from Lucy
  • When user information in Active Directory is changed: Automatically update existing recipient in Lucy with the new information.
