This is a FYI for sles12.

When I was setting up a new SLES server I hit problems with virtual hosts.
It seems that apache generates the Order & Allow commands rather than the newer Require command when you use yast/http.

Best edit the ip based hosts file manually. (a cut a paste from oes11 caused the problem this for me).

Could break an inplace upgrade when nxt version oes is available.
