Thank you!!  That did the trick.  The entirety of my authenticate
section is now:

 authenticate {
     Auth-Type Kerberos {
         krb5
     }
     Auth-Type eap {
         eap
         if ( "%{TLS-Client-Cert-Subject}" =~ /\/OU=Evil\// ) {
             reject
         }
     }
 }

And it works perfectly.  Thank you!

As for Windows XP dealing with the rejection....

Ah, thanks for the tip.  I added this in the "Post-Auth-Type REJECT"
section:

 if ( "%{control:Auth-Type}" == "EAP" ) {
   update reply {
     EAP-Message := 0x04010004
   }
 }

The code seems to work as expected, but Windows XP still doesn't seem to
handle it sensibly.  But I can live with that.

Thank you, Alan!
