We have set the asu.edu realm to be the default realm in the krb5.ini file.
The passwords between  AD domains and MIT Krb realms are identical. Still,
KfW doesn't auto-get asu.edu realm credentials. We can obtain credentials
using NiM AFTER standard windows logon. But it is just not getting them
automatically. Is there some other configuration option we have missed or
