<p class="MsoNormal">It certainly is, but it feels like a misconfiguration rather than a bug.<o:p></o:p></p>

<p class="MsoNormal">Your directory is sending referrals and you've configured the IDP to follow them, but I don't want to argue semantics.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">How do you think this should work?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">My first thought was to provide a component like StartTLSReferralHandler that you would have to configure, it would attempt to startTLS on any referrals.<o:p></o:p></p>

<div>
<p class="MsoNormal">One of the problems with relying on referrals is that you don't benefit from connection pooling, that may be a feature worth adding as well.<o:p></o:p></p>
