hanging from the roof.

  There were doors all round the hall, but they were all locked;
and when Alice had been all the way down one side and up the
other, trying every door, she walked sadly down the middle,
wondering how she was ever to get out again.

  Suddenly she came upon a little three-legged table, all made of

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

# All other users may do anything other than call PutObject
allow {
 input.action != "s3:PutObject"
