Hello!
I'm attempting to get Dovecot working with MySQL user database on another machine. I can connect to the MySQL (5.7.26) instance with SSL enabled:
mysql -h db.mrst.ee --ssl-ca=/etc/dovecot/ca.pem --ssl-cert=/etc/dovecot/client-cert.pem --ssl-key=/etc/dovecot/client-key.pem --ssl-cipher=DHE-RSA-AES256-SHA -u vmail -p
However if I use the same values in dovecot-sql.conf.ext, I get the following error:
Jul 19 00:20:18 turin dovecot: master: Dovecot v2.3.7 (494d20bdc) starting up for imap, lmtp, sieve (core dumps disabled) Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry
Database connection string:
connect = host=db.mrst.ee dbname=vmail user=vmail password=stuff
ssl_ca=/etc/dovecot/ca.pem
ssl_cert=/etc/dovecot/client-cert.pem
ssl_key=/etc/dovecot/client-key.pem
ssl_cipher=DHE-RSA-AES256-SHA
If I leave the ssl_cipher unset, I get:
Jul 19 00:23:41 turin dovecot: auth-worker(83069): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: Failed to set ciphers to use - waiting for 1 seconds before retry
Any ideas?
Thanks! Reio
