Disable Client Certificate Authentication for Unencrypted Connections?
I?m using dovecot to provide encrypted IMAP e-mail support for remote clients and it?s working great. However, I also need to set up a webmail front-end (Roundcube), which I?m hoping to have use unencrypted IMAP on port 143 (as only port 993 is available externally).
The problem I?m running into is that I want to require client certificate authentication on port 993, but dovecot is apparently

Curious problem: Plaintext authentication disallowed on non-secure (SSL/TLS) [read: all] connections.
Hello all,
I've set up a new instance of dovecot 2.0.9 to use as a POP3/IMAP proxy. On trying to login I am told '-ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections'.
I have set 'disable_plaintext_auth = no' (see output of doveconf attached). More curious still is that *this happens for SSL connections too*.
Something seems very wrong here.
Yelp?

disable_plaintext_auth = no as no effect on IMAP/POP3 logins
Hello
In my installation the disable_plaintext_auth does not appear to take
effect.
I can see that the value is correct using doveconf -a but it doesn't
change anything.
Whenever attempting to log in using IMAP I get this:
* BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but
your client did it anyway. If anyone was listening, the password was
exposed.

Problem with requiring client certificates for external connections
Folks,
I'm trying to configure my dovecot installation to require client
certificates for external/Internet connections, while still allowing my
local network to not need certificates.
This configuration is for Dovecot 2 (2.0.8 in Fedora 14), and I've
tried to use the "remote" block to give different definitions for my
local network vs the defaults. While most options seem to

I'm just wondering whether this is what caused my server to crash.

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

imap-login hangs after receiving revoked SSL certificate
Good time of the day!
My English is not very good, excuse me if I said something wrong.
I use dovecot-2.1.16 on Gentoo Linux amd64.
I need to setup dovecot (imap and pop3) for SSL and non-SSL connection
simultaneously. For SSL connections client must submit a valid SSL
certificate. Now SSL part of dovecot.conf looks like this:

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?

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.

How to make IMAPS SSL Cert for Dovecot that works with Thunderbird
Hello Aki and all,
The below lines are in the dovecot config file. This seems to be the
same as Aki's suggestion. correct? I have also double checked file
perms, tried with several new key gens, several versions of thunderbird
and created completely new thunderbird profiles.
Thank you,

Plaintext Authentication from Localhost
Hi:
It appears that at least at one time, Dovecot supported plaintext
authentication from localhost, even if disable_plaintext_auth = yes. To wit,
the example configuration file reads:
# Disable LOGIN command and all other plaintext authentications unless
# SSL/TLS is used (LOGINDISABLED capability). Note that 127.*.*.* and
# IPv6 ::1 addresses are considered secure, this setting has no effect

PHP API for Manager - Plaintext auth needed?
Quick question: My PHP script is now able to connect to the manager port
and successfully authenticate using MD5. I would strongly prefer not to
do plaintext authentication at all. Would anyone object to plaintext
authentication being left out?
