multisite, https setting "force ssl admin" unchecked for new sites

In the network administration area of our multisite install, the default setting for new sites is set to “force ssl admin”. However, when we create new sites, that checkbox is not checked. The wreaks all kinds of havoc with our custom authentication. The only two plugins we have enabled are this one and Shibboleth. I’ve tested in on three different multisite instances.
