The intention was that you could have "user1@domain" in tag1 and "user1@domain" in tag2 and they would be different users. So when you're returning a new tag from passdb then director just treats it as a different user. The old user is remembered until director_user_expire has passed without the user being accessed.</div><br class=""><blockquote type="cite" class=""><div class=""><div class="">I currently disable the domain in our dict used for userdb and passdb, clear the auth cache of all directors and flush them, before (final) rsync of the mailboxes of the domain to the new backend. When our dicts answer again with the new director tag, connections are going to the correct backend-pair. But it takes some hours for the old mapping to disappear.<br class=""><br class="">Is that the expected behavior?<br class=""></div></div></blockquote><div><br class=""></div><div>Yes.

That's not what is really happening. It's moving <a href="mailto:anything@domain.de" class="">anything@domain.de</a> in backend2's tag from its currently assigned backend to backend2. If <a href="http://domain.de" class="">domain.de</a>'s backend was already backend2 then nothing is done. You could maybe kludge this by moving it to backend1 and then quickly to backend2 so at least one of them does the kicking.</div><div><br class=""></div></div></div></body></html>
