Title: #703: nss: sssd returns '/' for emtpy home directories
I also had a follow-up discussion with simo on IRC, let me paste rephrasing:
- the AD provider should have an AD specific internal option that generates the homedir.
This option doesn't have to be exposed as a generic config option to avoid having yet
another configuration knob
- if fallback_homedir is set, this option is ignored
- the option should be ideally set to what winbind uses
I hope I haven't forgotten or mangled anything.
