Why does dovecot reject password when authorizing by a certificate?
We have FreeBSD-server with dovecot installed on it as IMAP-server. My user and password database is a text file with plaintext passwords. Clients connect to imap-server via TLS protocol and plaintext password. All works fine. But I want to configure ability to authorize with a client certificates. I have generated a client certificate and imported it to email-client. Also I have configured dovecot to verify client certificates. But email-client cannot authorize: Password mismatch. Why dovecot reject my password in this case? Please help!

I have added "auth_debug_password=yes" to "10-logging.conf" and restarted dovecot. But I do not see any information about the password in the logs.

You probably need to also enable
auth_debug=yes
auth_verbose=yes
also, are you sure you just don't have wrong password?

My configuration already contained these parameters (auth_debug=yes and auth_verbose=yes). I enter the same password in case of SSL-authorization and in case of authorization by certificate. In first case password has accepted, in second case password has rejected. I have no ideas.
