You don't need to sync anything --- you can give kerberos
administrative rights to any principal. Just put the principal
in your kadmind.acl file, e.g. put "foo@REALM" in that file,
and now foo@REALM has whatever powers you've granted it in
the acl file.
That said, I much prefer to create and grant administrative
powers to administrative instances for every service that
allows me to do so. Translation: I think it is really a bad
practice to grant all powers to 'foo@REALM'. My normal account
doesn't really have much power, but when I need to do
something more powerful (and potentially more dangerous) I get
admin credentials, do it, and get rid of those credentials.
It minimizes the amount of time in which I can really screw
