[horde] Upgrade from 5.1 to 5.2.6, Active Sync logging not working

[Claudio ML]

Hello all,

I have some problems with ActiveSync syncing calendars from Android or
Iphone, or Outlook 2013. I am trying to debug this, but every
configuration i can make, no files written into the directory. Here is
the configuration part rilevant:

$conf['activesync']['params']['driverconfig'] = 'horde';
$conf['activesync']['storage'] = 'Sql';
$conf['activesync']['emailsync'] = false;
$conf['activesync']['version'] = '14.1';
$conf['activesync']['auth']['type'] = 'basic';
$conf['activesync']['autodiscovery'] = 'full';
$conf['activesync']['outlookdiscovery'] = false;
$conf['activesync']['logging']['path'] = '/var/log/apache2/activesync/';
$conf['activesync']['logging']['level'] = '1';
$conf['activesync']['logging']['type'] = 'perdevice';
$conf['activesync']['ping']['forcedheartbeat'] = 60;
$conf['activesync']['ping']['deviceping'] = false;
$conf['activesync']['ping']['waitinterval'] = 15;
$conf['activesync']['enabled'] = true;

The apache that runs Horde have the permission to write in that folder,
but no files created at all. Looking at the horde.log (debug level
activated), no errors at all.

My versions are:

Horde (horde)
<https://webmail.mediaservice.net/horde/admin/config/config.php?app=horde>
5.2.6
Calendario (kronolith)
<https://webmail.mediaservice.net/horde/admin/config/config.php?app=kronolith>
4.2.8

Any help about this?

Cordially,

Claudio.
