<div>Nevermind, I re-read it and missed the M portion of dropped. Sorry for the confusion.</div>
<div><br>
</div>
<div>I have opened a puppet bug for this so we can switch the default value, it’s still eventlet.</div>

<div>Can you clarify if the feature is being deprecated – as in still usable but not recommended with a warning, or dropped, as-in, won’t work at all? You mention both in the first two sentences.</div>

<div id="bloop_customfont" style="margin: 0px;">The Keystone development team is planning to deprecate deployment of Keystone under Eventlet during the Kilo cycle. Support for deploying under eventlet will be dropped as of the “M”-release of OpenStack.</div>
<div id="bloop_customfont" style="margin: 0px;"><br>
</div>
<div id="bloop_customfont" style="margin: 0px;">The reasoning behind this move is multifaceted but the core of the reasons are as follows:</div>
<div id="bloop_customfont" style="margin: 0px;"><br>
</div>
<ul>
<li>Keystone relies on apache/web-server modules to handle federated identity (validation of SAML, etc) and similar SSO type authentication (Kerberos).</li><li>Eventlet has proven problematic when it comes to workloads within Keystone, notably that a number of actions cannot yield (either due to lacking in Eventlet, or that the dependent library uses C-bindings that eventlet is not able to work with).</li><li>Keystone has recommended (for multiple cycles) deploying Keystone under apache instead of eventlet. In the gate we primarily test all new development under Apache/mod_wsgi deployments. </li><li>Most deployers I’ve discussed keystone deployment with are either already on httpd+mod_wsgi or looking to move that direction (for support of features such as federated auth).</li></ul>
<div>The review to finalize the deprecation is: <a href="https://review.openstack.org/#/c/157495/">https://review.openstack.org/#/c/157495/</a> (Please only provide comments on deprecation, verbiage can be modified separately from the actual act of deprecation).</div>
