Documented steps

  1. Create the policy first if needed: `mc admin policy create ALIAS POLICYNAME policy.json` (any IAM-compatible JSON document).
  2. Attach it with `mc admin policy attach ALIAS POLICYNAME --user USERNAME` (or `--group GROUPNAME`).
  3. Attach multiple policies by listing several names before the `--user`/`--group` flag.
  4. Verify bindings with `mc admin policy entities ALIAS --user USERNAME` (or `--group` / `--policy`).
  5. Remove a binding with `mc admin policy detach ALIAS POLICYNAME --user USERNAME`; delete an unused policy with `mc admin policy rm`.
