You may have missed a documentation reference in Krb5.pm:
-------
=item get_krbhst(realm)

Returns a list of the Kerberos servers from the specified realm.
-------
which raises the issue of how much Perl code out there may call
Authen::Krb5::get_krbhst($realm) .

As far as my own needs are concerned it's OK to drop this function,
but it is an API change and may deserve a bump in the module's version number.

Alternatively, one could lift the implementation of krb5_get_krbhst (in terms
of profile_get_values, which is a public interface) from older libkrb5, or
provide a new one if there are licensing issues. Of course this is more
work and best left to upstream.

As a stop-gap, maybe one could keep Authen::Krb5::get_krbhst but with a
dummy implementation that always returns undef?
