How to configure activiti-explorer for SSO?

I have activiti-explorer 5.13 deployed at the weblogic 10.3.6. application server with kerberos SPNEGO authentication and authorization against Active Directory (like this example: http://biemond.blogspot.com/2011/08/single-sign-on-with-windows-kerberos-on.html ).To obtain SSO, usual method is to s

You probably will need to tweak the source code of Explorer, cause it will show the login page always otherwise

Thank you for response. Unfortunately, I'm not a skilled java developer, so this answer will not be enough to guide me. What I was able to understand (if not mistaken) is that support for SSO is partially implemented. For instance, this code in the ExplorerApp.java:

<java>
public void onRequestStart(HttpServletRequest request, HttpServletResponse response) {
    // Set current application object as thread-local to make it easy accessible
    current.set(this);

    // Authentication: check if user is found, otherwise send to login page
    LoggedInUser user = (LoggedInUser) getUser();
    if (user == null) {
      // First, try automatic login
      user = loginHandler.authenticate(request, response);
      if(user == null) {
        if (mainWindow != null && !mainWindow.isShowingLoginPage()) {
          viewManager.showLoginPage();
        }
      } else {
        setUser(user);
      }
    }

    if(user != null) {
      Authentication.setAuthenticatedUserId(user.getId());
      if (mainWindow != null && mainWindow.isShowingLoginPage()) {
        viewManager.showDefaultPage();
      }
    }

    // Callback to the login handler
    loginHandler.onRequestStart(request, response);
}
</java>

This ends in the DefaultLoginHandler.java and looks like dead end:
<java>
public LoggedInUser authenticate(HttpServletRequest request, HttpServletResponse response) {
    // No automatic authentication is used by default, always through credentials.
    return null;
}
</java>

Is this the right place to extend code and what would be advice?

Boris

Yes, the LoginHandler is the place where you want your custom logic to be implemented and use any environment you need for performing SSO (cookies, …)
