<p>Right from <a href="https://github.com/monitoring-plugins/monitoring-plugins/pull/1195#issuecomment-33554590" class="issue-link" title="check_ldap: add certificate support">#1195 (comment)</a>:</p>

<p>I noticed is that for straight up SSL services, check_http certificate check works! Makes me think the check should actually be implemented in check_tcp for all SSL protocols.</p>

<p>Then once we get there, what prevent us form adding just the required logic in check_tcp to implement the STARTTLS certificate checks for every other STARTTLS-cabaple protocol?</p>
