Why does dovecot reject password when authorizing by a certificate?

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. Does this mean that the thunderbird does not send the
password??Although it asks for the password and I enter one.
New log:

Why does dovecot reject password when authorizing by a certificate?

You probably need to also enable

auth_debug=yes

auth_verbose=yes

also, are you sure you just don't have wrong password?

Why does dovecot reject password when authorizing by a certificate?

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.
