<br>
I'm using sslbump and I just got blocked logging into hotmail for the<br>
first time (yeah, slumming it ;-)<br>
<br>
The cert is for <a href="http://bay181.mail.live.com" target="_blank">bay181.mail.live.com</a>, and squid is generating a "CN=Not<br>
trusted by xxxxx" type cert, as I assume it wasn't signed by a CA that<br>
squid knew about?<br>
<br>
I whitelisted <a href="http://live.com" target="_blank">live.com</a> (ie don't bump it any more) and the problem goes<br>
away for Firefox<br>
<br>
I'm running Ubuntu 14.04, so does this mean that the db of CA's Ubuntu<br>
trusts does not include the same CA-chain that browsers do?<br>
<br>
ie, I have<br>
<br>
http_port 3128 ssl-bump cert=/usr/local/squid/etc/squidCA.cert<br>
capath=/etc/ssl/certs/<br>
<br>
so this means the CA's Ubuntu lists in /etc/ssl/certs/ is "out of date"<br>
compared with Firefox?<br>
<br>
Really a rhetorical question, just kinda wanting to know about where<br>
sslbump will run into trouble, etc :-)<br>
