Android VPN Client - Constraint check failed: identity required<br> </font> </div> <br>
Hi Mark,<br><br>> Is this set for the android client only because I have never set the<br>> subjectAltname field for any of my certificates before, I only have<br>> this problem with the android client.<br><br>No that's also the case for other configs. But with ipsec.conf the<br>value for rightid can explicitly be configured, and if not, it defaults<br>to the DN of the certificate, if rightcert is configured, or to the<br>value configured with right (i.e. to %any if right is not configured).<br>rightid=%any is very risky for initiators as it allows any peer with a<br>valid certificate to act as gateway, therefore, the Android app uses the<br>configured hostname as expected rightid. If the other peer uses a<br>different identity (e.g. the DN of the certificate, which is the default<br>if leftcert is configured but leftid is not) the app also tries to<br>verify this identity against all subjectAltNames contained in
the<br>certificate.<br><br>Regards,<br>Tobias<br><br><br> </div> </div> </div></body></html>
