KDC_ERR_WRONG_REALM 68 Reserved for future use
is being returned by Active Directory because your users are
attempting to obtain a Kerberos TGT for a realm that
is not hosted on the server to which they are authenticating.
The existing MIT Kerberos distribution that you are using does
not know how to respond to this error. Windows machines can
attempt to search the Active Directory Global Catalog in order
to determine the actual principal name to use for authentication.
Perhaps someone has a PAM module written that can re-write the
principal name based either upon local rules or a series of LDAP
lookups against Active Directory. Unfortunately, I am
not aware of one.
