title: Pac4j Scala - Multiple SAML2 clients in secure action
body: <p>I have a <code>pac4j</code> <code>Config</code> with two <code>SAML2Client</code>:</p>
  <pre><code>val clients = new Clients(baseUrl + &quot;/domain/callback&quot;, samlClient1, samlClient2)
  val config = new Config(clients)
  </code></pre>
  <p>My question:</p>
  <p>How do I specify the client I want to use in a secure action if both clients are <code>SAML2Client</code>?</p>
  <pre><code>def SAMLSecure: SecureAction[SAML2Profile, AnyContent, AuthenticatedRequest] =
      Secure(
        clients = &quot;SAML2Client&quot;, // How to specify samlClient1 or samlClient2
        authorizers = myAuthorizers,
        matchers = myMatchers
      )
  </code></pre>
