The *samba-dc* role now configures `winbindd` on domain controllers to
support identity mapping on the local machine. This will allow domain
users to log into the domain controller itself, e.g. via SSH.
The Fedora packaging of *samba4* still has some warts. Specifically, it
does not have a proper SELinux policy, so some work-arounds need to be
put into place in order for confined processes to communicate with
winbind.
Evidently, some files in `/var/lib/samba` match multiple file context
rules. Thus, when running `restorecon` against the entire
`/var/lib/samba` directory, files in the `bind-dns` subdirectory may end
up with the wrong label. To work around this issue, `restorecon` is now
run only on that subdirectory to ensure the correct labels are applied.
This is likely to cause problems when a full filesystem relabel is
scheduled.
The *samba-dc* role installs Samba on the managed node and configures it
as an Active Directory Domain controller. A custom module,
`samba_domain` handles the provisioning using `samba-tool domain
provision` in an idempotent way.
