This document explains how to add LDAPs login credentials in Apinizer and how to log in to Apinizer with your LDAP users as an example. ## 1) Adding LDAPs Connection Information Open the **Connection Management → LDAP/Active Directory** page and add your information. In the **Server Address** field, start with **ldaps\://** followed by the **ldap domain** and then add port **636**. An example image containing LDAPs connection settings is shown below: LDAPs Connection Settings Check the **Use SSL** button for SSL usage. If **Certificate Required** is selected in the **Certificate Status** field, see [this address](/en/admin/secrets-management/certificates) to add a certificate. You can also add a restriction to the search using the **Custom Filter** field. For example, the filter **(&(objectClass=inetOrgPerson)(mail=[example@example.com](mailto:example@example.com)))** will work for users belonging to the **"inetOrgPerson"** class with email address **"[example@example.com](mailto:example@example.com)"**. In LDAP, users and groups are usually stored under different organizational units. Therefore, different **base DN** addresses can be given for users and groups: * Base DN for users: `ou=Users,dc=example,dc=com` * Base DN for groups: `ou=Groups,dc=example,dc=com` After entering your LDAP information, select one from the **Environment** field on the same page and click the **Test Connection** button. When the operation is successful, you will see an output like in the example image below. Test Connection Successful You can complete adding LDAPs information to your system by clicking the **Save and Deploy** button. ## 2) LDAPs Login Settings This section contains LDAP connection configurations that will enable integration with identity management systems available in organizations and accessible via LDAP connection so that users can log in to Apinizer. Open the **Administration → System Settings → LDAP Settings** page. LDAP Settings Page Give a name to the connection as shown in the image above and select the LDAP connection you added in the previous step from the **LDAP Connection** section. Click the edit button marked with red areas and enter the relevant information. An example usage for the **User Object Class Definition** popup page is shown in the image below: User Object Class Definition You can view how the relevant fields for **User** in the example image above can be filled by connecting to your existing LDAP application.
