Looks like two clients accessing a system with slightly broken authentication failover. - User 1, has (NTLM?) login working and gets through. - User 2, has no (NTLM?) login and gets redirected to a backup login (form?). Then things go all funky on User2. Going only by the URL; the 'AutoLogin=no' POST request (login form submission?) is denied because the (NTLM?) fails. BUT, that failure maybe is why the POST exists in the first place. **** Please verify manually yourself, if my theory above is correct about the two login methods before trying to fix. **** If my analysis is right. You need to whitelist POST requests to the backup login form handler. Maybe get the system POST'ing to a different URL (ie. */login?AutoLogin=no) which can be specially whitelisted by itself.
