(this looks out-of-dated)

1. pkg install openldap-client (Not really necessary, but useful for testing LDAP)
2. copy /usr/local/etc/openldap/* files from freefall.freebsd.org to the Jenkins host

1. make sure that Jenkins LDAP Plugin is installed
2. follow Jenkins Standard Security Setup, configuring LDAP
   1. Enabled Matrix Based Security. Create a user in the UI with the same login id as in LDAP.
   2. Look at the config files in /usr/local/etc/openldap/ and put enter the parameters in the Jenkins LDAP Plugin cofiguration UI
   3. Use ldaps:// for the URL so that SSL is used.

For ldaps:// , it may be necessary to add the certificate associated with the LDAP server to the JDK's list of trusted certificates. This is especially true if the certificate is self-signed or not built-in JDK. If you don't do this, then authentication errors will occur.

If this is necessary, then you should:

1. Make sure that the opendjk is installed from ports / pkg.
2. Read: https://issues.jenkins-ci.org/browse/JENKINS-3810
3. Obtain the certificate for the LDAP server from https://www.gandi.net/static/CAs/GandiStandardSSLCA2.pem
4. Copy default cacert file from $JAVA_HOME/lib/security/cacerts to $JENKINS_HOME/cacerts
5. Import certificate:

keytool -import -trustcacerts -file GandiStandardSSLCA2.pem -keystore $JENKINS_HOME/cacerts

(Default password for openjdk certificate store is: changeit)

1. Make jenkins use this new keystore by adding this line to /etc/rc.conf:

jenkins_java_opts="-Djavax.net.ssl.trustStore=/usr/local/jenkins/cacerts"
