Bug#774823: TimedLogin fails if disable-user-list is true

Package: gdm3
Version: 3.14.1-3
Severity: normal

If user list is disabled ("disable-user-list=true" in
/etc/gdm3/greeter.dconf-defaults), TimedLogin fails to do anything.

It seems that the functionality is bound to the user listing, which is
unfortunate because I consider the said functionality to be a security

It seems to me that TimedLogin should work regardless, or at least that
the behavior should be documented. I looked here in the documentation:
