    Use AUTHENTICATION_METHOD setting · c608941f

    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.
