i am modify the config.inc.php file..
the client is running Roundcube 0.9.2.
in a test setting, i install roundcube 1.1.4 and with some adjustmunts it works.
some settings are needed between ' '.. some settings not..
that is not documentated..
i am talking with the client to complete renew the current roundcube version for this.
but for now.. with the current version it does not work ..
globbal addressbook is available.. but every user can edit, no groups possible.
1 thing i miss... prevent users to copy contact from global to personal.. because of copy.. when the contact in global is changed.. the contact does not change in personal (its a copy).
