Are you actually using Kerberos in your FIM setup?

When installing FIM 2010 R1/R2 it is recommended to use Kerberos throughout the installing; in fact some parts of FIM just won't work without it. But how to you actually verify that you're accessing and getting validated on your websites using Kerberos and not 'just' NTLM?

I want to point you in the direction of a nifty little tool that I always use to verify that I'm using Kerberos on, let's say, the FIM 2010 R2 Password Reset and Registration Portals.

Have a look at it on Michel Barnevelds blog for his Kerberos Authentication Tester and go check those websites/services of yours.
