<p>A test on my own server shows it correctly failing, as expected. I tested against your server with that IP address and it also fails hostname verification:</p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<pre class="code-java">javax.net.ssl.SSLPeerUnverifiedException: SSL peer failed hostname validation <span class="code-keyword">for</span> name: 157.1.72.50
at org.opensaml.ws.soap.client.http.TLSProtocolSocketFactory.verifyHostname(TLSProtocolSocketFactory.java:233)

</pre>
</div></div>
<p>If you are seeing it working in your IdP, I wonder if you are being affected by another related bug that we can't really fix. If you are using the 'disregardSslCertificate' option on any other metadata provider configs, that's going to cause them all to work as if 'disregardSslCertificate' is set to true. That was basically <a href="https://issues.shibboleth.net/jira/browse/JOWS-38" title="HttpClientBuilder is setting a global Protocol and socket factory for 'https' scheme"><del>JOWS-38</del></a>. There was also a security advisory that we sent out:</p>
<p><a href="http://shibboleth.net/community/advisories/secadv_20130417.txt" class="external-link">http://shibboleth.net/community/advisories/secadv_20130417.txt</a></p>
<p>If that's not it, then I don't know of another reason why it should work with the IP address. We don't do any reverse IP->name lookup, and from what I can tell, neither does the hostname verifier implementation in the library that we use.</p></div>
