Hi,
I have, in one customer, a web server running on a Verisign-signed certificate SSL certificate. Everything works fine, IE and Firefox connects on https without asking anything, which usually happens on self-signed certificates. I'm trying to use that certificate on dovecot, but clients (Thunderbird basically) keeps saying the certificate is not valid.
yes i'm using, when configuring Thunderbird, the same CN that was signed by Verisign for the web usage
i've enabled verbose_ssl and got when thunderbird tries to connect:Feb 18 12:32:02 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.xxx.xxx, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca
unknown CA ???
is that Thunderbird that is not recognizing the Verisign-signed certificate ? Do i need to, somehow, install some Verisign CA certificate in dovecot.conf ?
when using a self-signed certificate, i also get an SSL_accept failed, but with different message:
Feb 18 12:41:45 correio dovecot: imap-login: Disconnected (no auth attempts): rip=201.86.191.114, lip=192.168.1.2, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate
despite the fact my certificates were generated for use with Apache, i can 'print' them, both of them, with the same commands i use to print dovecot generated certificates, with mkcert.sh. So, it seems they are compatible.
if i click OK on Thunderbird, when using my Verisign-signed certificates, everything works and i do got TLS logs:
Feb 18 12:23:36 correio dovecot: imap-login: Login: user=user@domain.com.br, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) Feb 18 12:31:43 correio dovecot: imap-login: Login: user=user@domain.com.br, method=PLAIN, rip=201.86.xx.xx, lip=192.168.1.2, TLS, TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)
what am i doing wrong ?? or using a signed-certificate for WEB usage is not possible on dovecot ?
