1151313 - Authentication failure connecting to imap server (bad certificate?)

Status: RESOLVED WORKSFORME

(Thunderbird :: Security, defect)

Description

[sam morris]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.76 Safari/537.36

Steps to reproduce:

Tried to receive mail from the IMAP server imap.robots.org.uk


Actual results:

Frontend says "The IMAP server {account name} does not support the selected authentication method. Please change the 'Authentication method' in the 'Account Settings | Server settings'."

According to the IMAP server logs:

    Apr  5 13:50:43 traxus dovecot: imap-login: Disconnected (no auth attempts in 2 secs): user=<>, rip=192.0.2.1, lip=37.139.10.94, TLS: SSL_read() failed: error:14094412:SSL routines:SSL3_READ_BYTES:sslv3 alert bad certificate: SSL alert number 42, session=<jEq6d/oSiQBWDzs8>

It looks like Thunderbird is rejecting the server's certificate, but it doesn't actually tell the end user this, nor does it log it in the error console.

The certificate is fine, at least it used to work until today, and still works with mutt, Evolution and K9.


Expected results:

Connection to IMAP server should have worked.

I have been experiencing periodic IMAP authentication failures to Google's Gmail. I have used restarting Thunderbird and even an OS reboot when that failed. Of course, I have no idea what EITHER of those things might have or not have done. This since upgrading to 60.4.0 for Mac.

Sam, do you still experience this issue using a current version?

This hasn't been reported to me for quite some time now.
