Paul, After 1.5.2 update to svn 14501, I can no longer log in to squirrelmail. I have used the same squirrelmail setup for at least the last 6-8 years. The current server is: Server : Archlinux x86_64 (squirrelmail on same machine) apache : 2.4.12-4 dovecot: 2.2.18-1 It had been many months since the last update. So I did the normal 'svn update *'. Then ran config/conf.pl and check the config -- all good. (saved the new config as suggested in doc/UPGRADE). In the past, squirrelmail has not checked whether whether the dovecot.pem certs were expired, but upon first attempt to login I received the following failure: Jun 12 17:58:22 phoinix dovecot[469]: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=::1, lip=::1, TLS handshaking: SSL_accept() failed: error:14094415:SSL routines:ssl3_read_bytes:sslv3 alert certificate expired: SSL alert number 45, session=<b1x8C1oYlQAAAAAAAAAAAAAAAAAAAAAB> Checking the cert with: 'openssl x509 -in certs/dovecot.pem -noout -text' showed that the cert was expired: Not Before: Dec 6 05:06:32 2013 GMT Not After : Dec 6 05:06:32 2014 GMT So I regenerated and installed the new certificates: Not Before: Jun 12 23:21:37 2015 GMT Not After : Jun 11 23:21:37 2016 GMT All operation through Thunderbird (sending/receiving) works fine with the new certificates, so the server isn't the issue -- it's squirrelmail. Attempted login via squirrelmail still fails: Jun 12 18:32:06 phoinix dovecot[469]: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=::1, lip=::1, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca: SSL alert number 48, session=<rM0jhFoYnAAAAAAAAAAAAAAAAAAAAAAB> Strange? The error has changed from: TLS handshaking: SSL_accept() failed: error:14094415:SSL routines:ssl3_read_bytes:sslv3 alert certificate expired: SSL alert number 45 to TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca: SSL alert number 48 So something in squirrelmail isn't handling the TLS handshaking: SSL_accept() quite like it used to. Let me know what else I can do or test to help isolate the problem. I'd like to get me squirrelmail install back up and running or I will have a lot of upset users in the morning. Any help appreciated. Thanks. -- David C.
