Client side certs may not work Just a thought: Do you have "Use secure authentication" checked in Thunderbird's server settings for that account? It's always annoyed me that you can't explicitly set which "secure" mechanism to use (CRAM-MD5, DIGEST-MD5, GSSAPI, etc.). I wouldn't be surprised if it's trumping the other mechanisms because you have a client certificate installed. ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
