[horde] Storing session in memcached (Horde Webmail 5.2.22)

[listas.correo]

Hi,

I'm trying to use memcache for horde sessions but it seems that I 
configured something incorrectly because it ignores my configuration.

This is what I have tried:

configure php handle and path to memcached instances:

# grep -e ^session.save_handler -e ^session.save_path /etc/php.ini 
session.save_handler = memcache
session.save_path = "tcp://127.0.0.1:11211,tcp://127.0.0.1:11212"

enable failover and redundancy:

# grep -e ^memcache.allow_failover -e ^memcache.session_redundancy 
/etc/php.d/memcache.ini
memcache.allow_failover=1
memcache.session_redundancy=3

configure conf.php:

# grep session /var/www/html/config/conf.php
$conf['session']['name'] = 'Horde';
$conf['session']['use_only_cookies'] = true;
$conf['session']['timeout'] = 0;
$conf['session']['cache_limiter'] = 'nocache';
$conf['session']['max_time'] = 72000;
$conf['sessionhandler']['type'] = 'Builtin';
$conf['sessionhandler']['hashtable'] = false;

the 'Builtin' type is described as:

"If you have configured a custom session extension in php.ini (such as 
native memcache sessions) then you should use this option. Horde doesn't 
force PHP to use the file-based session handler, so your php.ini 
settings settings will be deferred to."

so I understand that it is the correct value.


and check current values with test.php, but as you can see the "Local 
Value" column (the one used by horde) shows the "file" handle whilst the 
"Master value" shows the value configured in php.ini.

why the "Local value" isn't changed to memcache?
