No, just found it on several instructions on the net. After putting the
keys back in I came out with "Operation ot permitted". Setting the
"/etc/exports" to require gss/krb5 finally resulted in a successful
mount. Strangely showmount lists both host based and krb based
authentication, when /etc/exports has host based authentication selected.
