This is reasonable even for cname records asRFC 1034 requires that cname entries be resolvable. So, in this case it would seem that the cname record was incomplete and that's why xroot complained. > Wouldn't be possible for xrootd to detect that even if there is host+ > setting, the dns name is a proper unique ip name and just use it? It should but the cname didn't reference anything useful as far as I can tell from the messages. In short, a cname record must refer to a properly registered DNS name and that seems to not be the case here.
