I would like to add a guest-session on a computer with Kubuntu 14.04 LTS and KDM as login manager.
The guest account should be non persistent like in Ubuntu 12.04 (account uses only /tmp file)
I've found this Guide to a guest session on login screen for Ubuntu 10.10 but is it still applicable for a recent Kubuntu ? I'd think there is a more direct method.
NB: A guest-session has a higher security settings by default, it doesn't allow access to filesystem files and all files are deleted upon logout since they're stored on /tmp.
NB2: kdm is used as login manager instead of lightdm on this computer
