*Edge for Private Cloud v. 4.16.09*

This section explains how to configure SSL for the external authorization server. For general
information, see [TLS/SSL](https://docs.apigee.com/api-platform/system-administration/ssl).

1. Install the external LDAP Certificate Services.
2. Obtain the Server Certificate.  
   For example: certutil -ca.cert client.crt
3. Change to your latest Java version home directory:   
   \> cd /usr/java/latest
4. Import the Server Certificate. For example:  
   sudo ./bin/keytool -import -keystore ./jre/lib/security/cacerts -file ***\<FULLY-QUALIFIED-PATH-TO-THE-CERT-FILE\>*** -alias ***\<CERT-ALIAS\>***  

   Where ***\<CERT-ALIAS\>*** is optional, but recommended. Replace ***\<CERT-ALIAS\>*** with a text name that you can use later to refer to the certificate, for example if you want to delete it.   

   **Note** : The Default Keystore password used by Java is '**changeit**'. If this has been changed already you will need to get your sysadmin to provide the keystore password so you add your certificate.
5. Open /opt/apigee/customer/application/management-server.properties in a text editor.
6. Change the conf_security_externalized.authentication.server.url property value as follows:  
   **Old Value** : ldap://localhost:389  
   **New Value** : ldaps://localhost:636
7. Restart the Management Server:  
   \> /opt/apigee/apigee-service/bin/apigee-service edge-management-server restart
8. Verify that the server is running:  
   \> /opt/apigee/apigee-service/bin/apigee-all status

## Testing the installation

See the testing section at the end of [Enabling
external authentication](https://docs.apigee.com/private-cloud/v4.16.09/enabling-external-authentication), and perform the same test described there.
