title: Trying to log in to Keycloak Admin WS
body: <p>I need to configure realms in Keycloak by the Admin WS accessible at the path </p>
  
  <pre><code>http://KeycloakServer:8081/auth/admin/realms
  </code></pre>
  
  <p>So in Postman I run the following request</p>
  
  <p>URL: <code>http://KeycloakServer:8081/auth/admin/realms</code></p>
  
  <p>Method: <code>POST</code></p>
  
  <p>Body: </p>
  
  <pre><code>{
      "enabled": true,
      "id": "TestRealm",
  }
  </code></pre>
  
  <p>I get a <code>401 Unauthorized</code> response, so I think it is necessary to authenticate to the Admin WS. But in the docs I cannot find any information about the type of authentication required and the syntax.
  Do you know how to authenticate to the Keycloak WSs?</p>
  
  <p>Thank you</p>
