class="xfm_51868779">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!<br>
