I has try config ldaps for jenkins but not working. i confused with this tutorial document. 

Anyone tell me that with step 4 i need add this config to where? I did try add it to /usr/lib/systemd/system/jenkins.service

Environment="JAVA_ARGS=-Djava.awt.headless=true -Djavax.net.ssl.trustStore=$JENKINS_HOME/.keystore/cacerts -Djavax.net.ssl.trustStorePassword=changeit"

As the picture below, i did success connect to AD with TLS enable and JDK TrustStore set

But when i change port 3268 to 3269 (LDAPS) it show me an error.
