Create a new admin user `admin1` on MinIO use `mc admin user`.

```
mc admin user add myminio admin1 admin123
```

Once the user is successfully created you can now apply the `userManage` policy for this user.

```
mc admin policy attach myminio userManager --user=admin1
```

This admin user will then be allowed to perform create/delete user operations via `mc admin user`
