Now, let's go ahead and edit /etc/krb5.conf

sudo nano /etc/krb5.conf

  ccache_type = 4
  forwardable = true
  proxiable = true

  north.newyork.local = {
      kdc = bronx.north.newyork.local
      admin_server = bronx.north.newyork.local
  }
  newyork.local = {
      kdc = nyc.newyork.local
      admin_server = nyc.newyork.local
  }
  maryland.local = {
      kdc = baltimore.maryland.local
      admin_server = baltimore.maryland.local
  }
