After a cursory look I think that krb5_get_cred_from_kdc_opt() could use
a small modification to produce a different error when no x-realm path
exists, around here:

   123    if ((retval = krb5_cc_retrieve_cred(context, ccache,
   124                                        KRB5_TC_MATCH_SRV_NAMEONLY | KRB5_TC_SUPPORTED_KTYPES,
   125                                        &tgtq, &tgt))) {
   127      if (retval != KRB5_CC_NOTFOUND && retval != KRB5_CC_NOT_KTYPE) {
   128          goto cleanup;
   129      }

Add something like:

      if (retval == KDC_ERR_S_PRINCIPAL_UNKNOWN) {
	  retval = KRB5_NO_XREALM_PATH;
	  goto cleanup;

And, of course, KRB5_NO_XREALM_PATH would have to be defined.
