NimbostratusKerberos 401 authentication with form fallback
Hello,
we are using APM for SAML authentication. Domain joined machines should authenticate transparently with Kerberos, users without the ability to use Kerberos (non domain joined, Firefox wit...
I don't immediately see how it's possible to tell if a PC is able to authenticate without asking it via a 401, which produces a browser auth pop-up. Is there anything in the initial HTTP request that you can use to tell this class of clients from the other class of clients?
Well, perhaps you could use Group-Policy IEM tool to modify the User-Agent and show the 401 to only those guys via some simple VPE logic? But they would have to use only IE, unless there is some way to do this with Firefox to a group of PCs.

NimbostratusHey AN, are you still having issues with this functionality? I am working on an issue right now where IE and Chrome WERE functional, but have stopped working. What we've noticed is that the authorization window is still presented, but we can just cancel it, and authentication is successful. It may be related to a Microsoft bug MS16-119. Can you attempt to cancel the login and see if that works?
Thanks!
