# Prerequisites
You must create an admin user like so:
```
radosgw-admin user create --uid admin --display-name "Admin User" --caps "buckets=*;users=*;usage=read;metadata=read;zone=read --access-key=2262XNX11FZRR44XWIRD --secret-key=rmtuS1Uj1bIC08QFYGW18GfSHAbkPqdsuYynNudw
Then use the `access_key` and `secret_key` for authentication.
Snippet usage example:
```golang
package main
import (
"github.com/ceph/go-ceph/rgw/admin"
)
func main() {
// Generate a connection object
co, err := admin.New("http://192.168.1.1", "2262XNX11FZRR44XWIRD", "rmtuS1Uj1bIC08QFYGW18GfSHAbkPqdsuYynNudw", nil)
if err != nil {
panic(err)
}
// Get the "admin" user
user, err := co.GetUser(context.Background(), admin.User{ID: "admin"})
// Print the user display name
fmt.Println(user.DisplayName)
