- Add a *userShell* key, which can be left out (default, backwards-
compatible) to retain the old /bin/bash behavior, or explicitly
set to empty to defer to useradd-configuration, or explicitly
set to something non-empty to use that shell.
- Warn here since it may not be what the Distributor want.
Having wrong groups may result in broken permissions for
created user.
- explain what defaultGroups is for in users.conf
- Introduce a map 'passwordRequirements' in users.conf,
which is a list of named requirements. There are only
two settings right now, min and max length, but
additional checks can easily be added in UsersPage.cpp
by defining additional lambda's to check the given
password string.
- Add PasswordCheck instances as needed, with functions
to check acceptability and to produce messages on rejection.
- Documentation in the users.conf file itself.
- In passing, refactor setting of pixmaps on labels.
FIXES#790
Fixes CAL-345.
Changing group of home dir to the default "users" group might be a security risk
because every user which belongs to the default "users" group
might be able to access private data on home dirs of other users.
