Samba 4.2 needs some more permissions for nmbd and winbindd. To avoid overcomplicated profiles, change abstractions/samba to allow /var/lib/samba/** rwk, (instead of **.tdb rwk) - this change already fixes the nmbd profile. winbindd additionally needs some more write permissions in /etc/samba/ (and also in /var/lib/samba/, which is covered by the abstractions/samba change and also results in some profile cleanup) References: https://bugzilla.opensuse.org/show_bug.cgi?id=921098 and https://bugzilla.opensuse.org/show_bug.cgi?id=923201 Acked-by: Seth Arnold <seth.arnold@canonical.com>
