Right now, if I want my wallet to unlock at login, I need to make sure its password matches my login password, and also manually install the kwallet PAM package and edit /etc/pam.d/<display manager>. This is cumbersome and un-user-friendly. It would be nice if there were a GUI option to make this easy for regular users--or just make it the default behavior!
Since this depends on the used display manager, the required PAM kwallet setup needs to be done by the distribution.
