[Dovecot] smartsieve managesieve-login failure with dovecot 2.1.7

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello,

I just subscribed to the mailing list because I am stuck trying to solve
a problem getting smartsieve to work with a new version of dovecot.
But let me first explain the situation shortly. I am running a mail
server at home for personal use, and for fun. At this moment this is an
old, slow machine running Debian Squeeze, Dovecot 1.2.15 and Exim 4.72.
Authentication is done with LDAP, running OpenLDAP 2.4.23. For managing
mail filtering I use Smartsieve 1.0.0-RC2 in conjunction with Dovecot's
Managesieve plugin. It's all working properly. But because this machine
is slow, I'm now busy upgrading building a new machine running Debian
Wheezy, Dovecot 2.1.7 and Exim 4.80. I've got it all running and working
now (that is: locally in my lan): imap with dovecot, smtp with exim,
Dovecot's sieve plugin working properly, authentication done through
LDAP backend.
But what I can't get to work is Smartsieve. Looking at the logs on my
server I can tell managesieve-login is not working well with Smartsieve.
As far as I understand authentication is always done over a secure
connection using TLS. Here is some logged output, Dovecot as well as
Smartsieve.

dovecot-info.log:

What is clear is that somehow no user information is being negotiated.

Issuing a manual TLS login give the following results:

root at amigos:~# gnutls-cli --starttls -p 4190 jingo.private-lotus.no-ip.net

Everything OK I guess. Especially the first part of the output is
interesting: "IMPLEMENTATION" "Dovecot Pigeonhole"
This is what Smartsieve is looking at. With the former version the
string was 'dovecot', so I changed this in the 'Managesieve.php'
file.
This file was already patched as stated on the site. Furthermore I
changed everything referring to port 2000 to port 4190.

But it still ain't working. Am I doing something wrong? Or is Smartsieve
just becoming too outdated to work with newer versions of Dovecot?

To get the picture complete, hereby my used config of Dovecot, generated
with 'dovecot -n' :

Any help would be appreciated.
Thanks in advance.

That should work. I used the patch mentioned here:

http://www.mail-archive.com/dovecot at dovecot.org/msg21862.html

And modified it for the new situation. I'm assuming this is very similar
to what you're doing and here it works.

You could try to obtain more information by logging the protocol exchange:

http://wiki2.dovecot.org/Debugging/Rawlog

Alternatively you can debug Smartsieve by adding more logging into the
source code.

And yes, SmartSieve is unmaintained, so I would not recommend using it
anymore.

Regards,

Stephan.

setup smartsieve to disable tls, then it works
