tokens. These tokens use Fernet keys, that are rotated from time to time. A<br>
great description of key rotation and replication can be found on [0] and [1]<br>
(thanks, lbragstad). In HA setup there are multiple nodes with Keystone and<br>
that requires key replication. How do we do that with new Fernet tokens?<br>

Please keep in mind that the solution should be HA -- there should not be any<br>
"master" server, pushing keys to slave servers, because master server might go<br>
down.</div></blockquote></div><br>In my test environment I was using ansible to sync the keys across multiple nodes. Keystone should probably provide some guidance around this process, but I don't think it should deal with the actual syncing. I think that's better left to an installation's existing configuration management tools.<br><br clear="all"><div><br></div>-- <br><div class="gmail_signature">David<br>blog: <a href="http://www.traceback.org" target="_blank">http://www.traceback.org</a><br>twitter: <a href="http://twitter.com/dstanek" target="_blank">http://twitter.com/dstanek</a><div>www: <a href="http://dstanek.com" target="_blank">http://dstanek.com</a></div></div>
