[horde] again: ingo: can't add rules

[A. Schulze]

Hello,

I have still a open issue: ingo and KolabImap as preference backend  
don't work.
see http://lists.horde.org/archives/horde/Week-of-Mon-20140915/052672.html

Now I melt down my config to a bare minimum to reproduce.
- install a mimimum horde from pear (released today: horde-5.2.9)
- goto http://localhost/ which is the horde root
- autologin as Administrator
- complete the configuration: ONLY set $conf[sql][phptype] to None.
- safe conf.php, logout & close browser

create ~horde/config/conf.local.php
      <?php
      $conf['testdisable'] = false;
      $conf['log']['priority'] = 'DEBUG';
      $conf['log']['name'] = '/tmp/horde.log';
      $conf['log']['params']['append'] = true;
      $conf['log']['type'] = 'file';

      $conf['auth']['driver'] = 'imap';
      $conf['prefs']['driver'] = 'KolabImap';

given this configuration horde authenticate via a local imap server  
and use it to store preferences.
This is a bare minimum configuration for dovecot (version 2.2.21):

dovecot.conf:

      ssl = no
      passdb {
        driver = static
        args = password=test
      }
      userdb {
        driver = static
        args = uid=65534 gid=65534 home=/tmp/%u
      }
      mail_location = maildir:~/Maildir/
      namespace {
        inbox = yes
        separator = /
        prefix = INBOX/
      }
      mail_attribute_dict = file:dovecot-metadata
      imap_metadata = yes
      protocols = $protocols sieve

Now I could login via imap at localhost with any username, password "test".
A maildir is created in /tmp/%username/Maildir/

Back to horde I login as "user" and get the notification "Last login: Never"
Logout and login again I now see "Last login: %timestamp from %host"
That's the indicator Horde *do* store preferences in  
/tmp/%username/Maildir/.Preferences

let switch to file based preference system: append two lines to  
~horde/config/conf.local.php:

     $conf['prefs']['params']['directory'] = '/tmp';
     $conf['prefs']['driver'] = 'File';

Logout an login again as user an notice the preferences stored in  
/tmp/%username.prefs

Now install ingo: pear install horde/ingo
Login as Administrator and configure ingo: ONLY set  
$conf[storage][driver] to "preference system"
Also create a backend: ~horde/ingo/config/backends.local.php
     <?php
     $backends['imap']['disabled'] = true;
     $backends['sieve']['disabled'] = false;
      
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['hostspec']  
= '127.0.0.1';
      
$backends['sieve']['transport'][Ingo::RULE_ALL]['params']['usetls'] =  
false;

Now, after login as user, goto http://localhost/ingo
Create rules, they are stored in 2 positions:
    1. /tmp/%username.prefs
    2. /tmp/%username/.dovecot.sieve linked to /tmp/%username/sieve/ingo.sieve

that works.

now switch back to $conf['prefs']['driver'] = 'KolabImap';
( comment the last two lines in ~horde/config/conf.local.php )

Logout and login. Create a rule, the rule is only saved in  
/tmp/%username/sieve/ingo.sieve

OS: Debian Jessie, http://localhost/test.php
