How the System Works

Overview

The AD integration feature has been designed and implemented to make setup and operation as effortless as possible for customers.
The key characteristics of TrustLogin's AD integration feature are as follows.

• It does not connect to your network environment from outside.
• The AD Connector uses only outbound communication. Inbound communication is not required.
• It only reads from AD and never writes to it. Administrator privileges are not required.
• AD passwords are never stored in TrustLogin. Since an authentication request is sent to AD
  every time a user logs in, login is always performed using the current AD password.
• No specialized knowledge is required for deployment (it is designed so that an AD administrator can deploy it within a few hours)

Setup Procedure

Advance Preparation

Expected operating environment: Windows OS with .NET Framework 4.8 installed
Verified operating environment: Windows Server 2016, 2019, 2022, 2025 / .NET Framework 4.8
　　　　　　　　However, Windows Server 2025 supports LDAPS only.

Note: Please run the installer in an environment with internet access.
Note: Running the installer requires local administrator privileges on the device.

1. Once your application for the AD integration feature is complete, you will be able to configure AD settings.
   Download the Connector installer from the "Settings ＞ Active Directory Integration ＞ Settings" button
   on the Admin Page.
   
   
   Note: Installer file details
   
   
   
   
2. Click "Connection Parameters" to check the details.
   Note: You will use this information when installing the Connector in a later step.
   
   
   
   
   
   

Installation Procedure

1. Double-click the downloaded file to launch the installer.
   
   
   
   
   
2. When the setup wizard dialog appears, click "Next."
   
   
   
   
   
3. If you have no specific preference for the installation destination folder, click "Next" as is.
   
   
   
   
4. Enter the connection parameters and click "Next."

About Logs

How to Check the Logs
By default, the AD Connector logs can be found in the following folder.

C:\ProgramData\TrustLoginADConnectorData\Logs
Note: Logs are created as a separate file for each day.

By default, logs are output in INFO mode. Switching to DEBUG mode allows more detailed logs to be output.

Note: DEBUG mode is intended to be enabled during troubleshooting in order to help identify the cause of an issue.
　Since the log file size may grow significantly and affect server performance, we recommend checking the server's available disk space beforehand, and switching back to INFO mode once the issue has been resolved.

How to Change the Output Level

1. Open the "Config" file from the Connector's installation folder.
   
   
   
   
   
2. Change "INFO" to "DEBUG" and save the file.
   
   
   ↓
   
   
   
   
3. In the Services management tool, right-click "TrustLoginADConnector" and select "Stop," then
   select "Start" again to restart it.
   
   
   
   
   
   
   

Uninstallation Procedure

1. To uninstall, use the same installer file that was used for installation.
   Note: Uninstalling removes the AD Connector, but the generated log files are not deleted.
   Note: If you also want to delete the logs, delete the following folder.
   C:\ProgramData\TrustLoginADConnectorData\Logs
   
   
   
   
2. Click "Next."
   
   
   
3. Click "Remove," and then click "Remove" again.
   
   
   
   
   
   
   
4. Removal will begin; once it finishes, click "Finish."
   
   
   
   
   
   
   

Removing a Connector

Connectors that have already been added can be removed from the list.
1. Hover your cursor over the displayed connector to display the delete button.

2. Click the "Yes" button to complete the removal.

Supplementary Information

With the discontinuation of the previously provided legacy AD Connector,
customers were asked to complete migration to the new AD Connector by the end of August 2025.

The benefits of the new AD Connector are as follows:
・Supports TLS 1.2
・Reduced file size
・Supports LDAPS with self-signed certificates
