Hello,
I have a problem with the Roundcube 1.2.3 under Debian 9.

In my config I set:

$config['log_session'] = true;

and

$config['session_lifetime'] = 20;

Unfortunately that doesn't work. Roundcube don't close session at all.
This big problem for me.

Except for this feature everything works fine.

Very thanks for all suggestions.
