<br>
SSL 9.0.2 mentions a patch to fix out of order cert chains<br>
<br>
In SSL 9.2 we have a root CA and an out of order cert chain<br>
for host <a href="http://hooks.glip.com" rel="noreferrer" target="_blank">hooks.glip.com</a>.<br>
<br>
When we try to verify peer with the out of order cert<br>
chain we get 'Unknown CA'.<br>
<br>
Is this expected behaviour for Erlang SSL 9.2 with verify_peer ?<br>
<br>
The <a href="http://erlang.org/doc/apps/ssl/notes.html#ssl-9.0.2" rel="noreferrer" target="_blank">http://erlang.org/doc/apps/ssl/notes.html#ssl-9.0.2</a> notes<br>
mention that other care may need to be taken to ensure compatibility.<br>
