iRony doesn´t work with imaps 993

[Christian Hügel]

Hi,

I´m trying to use cyrus with imaps on port 993. I have following config 
options in /etc/roundcube/config.inc.php


// IMAP Server Settings

     $config['default_host'] = 'ssl://localhost';
     $config['default_port'] = 993;


I can login in the webmailer and send/receive mails. However when 
accessing  kolabdav (iRony) https://example.com/iRony/calendars/ I 
cannot login.
Here are the iRony error logs:

IMAP Error: Login failed for test.user at example.com from 1.1.1.1. Empty 
startup greeting (localhost:993) in 
/usr/share/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 
184 (GET /iRony/calendars/test.user%40example.com)

and cyrus logs:

kolab imaps[26351]: imaps TLS negotiation failed: localhost [127.0.0.1]
kolab imaps[26351]: Fatal error: tls_start_servertls() failed


When changing the options to

  $config['default_host'] = 'tls://localhost';
  $config['default_port'] = 143;

everything works as expected.

Am I missing some configuration options? Thank you
