XMPP: Check id-on-xmppAddr and/or id-on-dnsSRV Subject Alt Names for certs

Reported by: hildjj Owned by: deryni
Milestone: Component: XMPP
Version: 2.10.6 Keywords:



According to RFC 6120, section 13.7.2 (, the client should check more than just the subject of the certificate to see if there is a name match. In particular, the Subject Alternative Names for id-on-xmppAddr and/or id-on-dnsSRV should also be checked for a match with the domain name that the user entered.

Note: This SHOULD NOT be checking the "Connect Server" for a match, but the portion after the @ in the user's Jabber ID.

Steps to reproduce

Connect to a server using SSL or TLS with a cert whose subject does not match, but which contains a proper Subject Alternative Name, where the cert is chained back to a trusted CA. See the scary popup warning about the name mismatch Click trust

Expected results

Login happens without security prompt.

Actual results

Scary security prompt.
