    ad: handle forest root not listed in ad_enabled_domains
    
    Although users and groups from the forest root should be ignored SSSD
    will still try to get information about the forest topology from a DC
    from the forest root. So even if the forest root domain is disabled we
    should makes sure it is usable for those searches.
