If you run Samba as an AD DC, then there's a problem with DFS referrals,
we currently only expect our hostname or our domain name as valid names.

I'm not sure if this is easily fixable...
Maybe we should just return NT_STATUS_NOT_FOUND instead of
NT_STATUS_INVALID_PARAMETER
for unknown names (in dfs_server_ad_get_referrals()).

Why do you want this behavior at all? Maybe it's better to have
a file server separate from the AD DC.
