Knowledge Base Article Link: https://www.liferay.com/group/customer/knowledge/kb/-/knowledge_base/article/30717691

Step To Reproduce

1. Go to Control Panel > Server Administration > Portal Instance and note the Web ID's of the two (or more) portal instances that you have. (If you have not created a second instance, create one in this step.)

2. Shut down the Liferay server, and navigate to ${Tomcat_Home}/webapps/ROOT/WEB-INF/classes and create a property file for each portal instance.
Title each file in the following manner: portal-{$instance_WebID}.properties

3.In the same path, create a system-ext.properties file, and add the following line to the file:
company-id-properties=true
4. Open Sentev.bat (or Sentev.sh in Linux) in {$Tomcat_Home}/bin and add the following line to the Java Settings:
-Dcompany-id-properties=true

5. Open the portal-{$instance}.properties files and add the following line
ldap.auth.enabled=true

Result of Testing
After following the above steps, not able to enable ldap propery through portal-ext.properties for different instance.

Logs
