the fact that we have to keep reinventing kerberos all the time because it doesn't speak http is starting to legitimately annoy me.
Chrome, Firefox, Internet Explorer -- all support some form of kerberos auth in HTTP/HTTPS.
The only places I've seen a working Kerberos setup outside of homelabs is universities (who can just throw endless amounts of free student labor power onto solving any IT problem) and large governments and international megacorps.
