Looks as if TSIG implementation is incomplete.


"|key-name| - if TSIG is used with this domain’s servers, this value
should be the name of the key from the TSIG Key List. If the value is
blank (the default), TSIG will not be used in DDNS conversations with
this domain’s servers. Currently this value is not used as TSIG has not
been implemented."
