Ahhhhh,  we all love to hate Microsoft.  But in this case Microsoft 
actually (according to them) played within the specs.  From what I've read 
about it, there is a place in the Kerberos Ticket to store some optional 
authorization data.  Microsoft took advantage of that but refused to make 
the contents of the optional stuff it added public.  Since Kerberos is an 
open protocol, it pissed some people off that Microsoft was adding some 
proprietary stuff to it.  I think there were also some broken promises by 
MS to eventually make the stuff it added public.  Later when they did make 
it available they did so under NDA.

I can tell you that the Windows 2000 and 2003 implementations of Kerberos 
work with other Kerberized applications.  I think MS did a very good job 
of implementing/integrating Kerberos with Active Directory.  Good enough 
that most Windows admins don't even know they are actually administering a 
Kerberos.  If you are interested in low cost SSO using EIM and Kerberos 
then using Windows 2/3k is a no-brainer.
