[imp] auto logoff

[Emily A. Carl]

Does the session.gc_maxlifetime configuration in php.ini apply to 
both files and cookies storage of the session information?

If it does, why would there be a session.cookie_lifetime configuration
also in the php.ini file?

AND...

I am a little confused about this php.ini configuration 
(session.gc_maxlifetime) and the
horde/config/conf.php $conf['session']['timeout'] configuration.

Does horde use php's session_set_cookie_params() call to override the
php.ini file's configuration of session.cookie_lifetime?

Why would horde have these configurations in its horde/config/conf.php
file with the same configurations being in the php.ini file?
