If the AD domain and the Kerberos realm have the same name (but not the same 
KDCs) you have a problem.

Some code will see ..@ND.EDU and try and use the KDCs for AD. Some code
will try and use your MIT Kerberos V realm. AFS will only be the first
of many problems you will have you you try and use the same realm name
for both. (For example the DNS SRV records can only point at one. KfW
if it imports tickets from Windows then trys to use the TGT against
you MIT Kerberos V realm.


  Rename one of the realms, and maybe use cross realm between them.

  Just use the AD KDCs for everything.
