The valid authentication methods are: - plain (nsupdate) - bind9 (nsupdate -k) - kerberos (nsupdate -g) The plain method assumes that the server allows updates without authentication (e.g. allow-update { 192.0.2.1;};). The bind9 method uses the -k option and requires a keyfile. The kerberos method uses the -g option and requires a principal and a keytab. For backwards compatibility if AUTHENTICATION_METHOD setting is missing in defaults file we use bind9. Signed-off-by: Dimitris Aragiorgis <dimara@grnet.gr>
