And Bill MacAllister spoke on 08/31/2009 06:01 PM, saying:
Using Pidgin 2.6.1 on Windows when a new user connects to our Openfire
Jabber server Pidgin complains that it cannot find the root
certificate for our Comodo certificate.  This does not happen using
Pidgin 2.5.5 on ubuntu or for other web applications that use other
Comodo certs on the same Windows system.  Is Pidgin on Windows being
shipped with a certificate store that doesn't contain the Comodo root?

Bill

On Windows (and *nix distributions that do not build using
--with-system-ssl-certs or do not offer a certificate directory), Pidgin
uses a limited set of CA certificates shipped with the program, which does
not currently include a Comodo root.

Could you point out which specific root CA you use (key fingerprint
ideally, some other uniquely identifying characteristic also works) so that
we can add it to Pidgin?

Just to make sure I got this right here is the chain that I see.
