Infinite Loop with NotLoggedInException

[ryneezy.ryan.samiley.live.com]

Trying to integrate my app with Oracle WebSSO. Unfortunately after I log in through WebSSO, Seam looks like it loses the identity then goes into an infinite loop with NotLoggedInException.

I have an Authenticator interface:

public interface Authenticator {
  boolean authenticate();
     
  void logout();
}

When WebSSO performs a successful authentication it puts the username in the Http Header with a customizable token. The WebSSO Authenticator looks like:

@Name("webSSOAuthenticator")
@SuppressWarnings("serial")
public class WebSSOAuthenticator implements Authenticator, Serializable {
  @In
  private Identity identity;

  public WebSSOAuthenticator() {
    super();
  }
        
        
  public boolean authenticate() {
    if (identity.isLoggedIn()) {
      log.info("authenticated");
      return true;
    }
                
    
    ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
    HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();

    String username = request.getHeader("USER_TOKEN");
    // Perform some authentication logic with the username
        
    SimplePrincipal principal = new SimplePrincipal(username);
    identity.acceptExternallyAuthenticatedPrincipal(principal);

        
    return true;
  }     
        
  @Override
  public void logout() {
    identity.logout();        
  }

Components.xml defines a factory to get the Authenticator since we also have another Authenticator for testing. I'm interested in the WebSSOAuthenticator.

<security:identity authenticate-method="${authenticator.authenticate"/>

<component name="authenticatorFactory" class="com.mycompany.AuthenticatorFactory" auto-create="true" scope="stateless"/>
     
<factory name="authenticator" scope="session" method="#{authenticatorFactory.getAuthenticator}"/>

Pages.xml:

<pages ... login-view-id="/main.xhtml">
  <page view-id="/main.xhtml">
    <action execute="#{authenticatorFactory.getType()}" if="#{!identity.loggedIn}"/>
    <navigation from-action="#{authenticatorFactory.getType()}">
      <rule if-outcome="web-sso">
        <redirect view-id="/login-websso.xhtml"/>
      </rule>
      <!-- Additional rule for testing... -->
    </navigation>
  </page>

  <page view-id="/login-websso.xhtml">
    <action execute="#{identity.login}"/>
    <navigation from-action="#{identity.login}">
      <rule if-outcome="loggedIn">
        <redirect view-id="/main.xhtml"/>
      </rule>
    </navigation>
  </page>
</pages>

I'm using Seam 2.2.1 CR1 with Apache Tomcat 6.0.26
