Windows clients sending windows credentials
We're trying a number of options for a space that's almost all "guest" access, and since web portals are awful with HTTPS everywhere, we're trying 802.1x EAP auth to a radius server.
For OS-X, it's been working great. User picks network, types in their credentials from our partner that runs the radius server, and away they go. Windows folks though... some connect with no issues. Others seem to be sending what appear to be their actual windows domain credentials (there are "\\" in the username, etc.) as opposed to sending the email/password that the on-site folks provide them. I am not a windows person, what is this fluke and on the AP side of things, is there any way to prevent this behavior?
