Kerberos has kadmin.local, and I'm looking for a similar way to execute admin commands
as the local root user. Looks like I could create a keytab, and use kinit on it, but
ipa-getkey doesn't seem to work for the admin principal. So I could create a new
service account instead, but I can't seem to find a role that grabs everything like
the special admin group does. Any tips?
