The plugin contains tabular markup on some form elements and will probably present issues with the tables-to-divs changes in https://issues.jenkins-ci.org/browse/JENKINS-62437

At least the following files may be affected:

• https://github.com/jenkinsci/active-directory-plugin/blob/master/src/main/resources/hudson/plugins/active_directory/ActiveDirectorySecurityRealm/config.jelly

Some migration recipes can be found on https://www.jenkins.io/doc/developer/views/table-to-div-migration/
