krb5_verify_user() is a function in the Heimdal implementation of
Kerberos, but is not present in MIT krb5.

Upon cursory examination, it seems that
krb5_get_init_creds_password() and krb5_verify_init_creds() together
might be a suitable replacement.  Note that it requires the caller
to have access to a service keytab (and the principal name must be
specified if it is not host/<localhost>).
