Re: Bypass RunAs

Sorry about the response lag.

I had originally just noted that it was possible to do this while installing
SUA on Vista; it has options for allowing setuid (and also sutoroot) during
install phase. I went back this morning and tried allowing setuid to work,
even reinstalling SUA, but I can't even find the binary - just the man page.

I think this is going to take someone who knows more about SUA to answer,
which kind of drives home the point that it isn't a practical solution for
most people.
