Smartclient Authentication system

[Medioman92]

Hi,
i'm trying to develop a simple smartclient CMS webapp and i'm stuck on the login process.
i've read a thousand time the "relogin" page without have any real clue because it's based on the idea of an external already existing authentication system that need to be integrated in SmartClient.
But what if i'd like to develop a smartclient login solution ?
Soo far i've followed the secureApp example and this is what i've modified in my project:

WEB.xml

<filter>
        <filter-name>AuthAdminAuthenticator</filter-name>
        <filter-class>com.isomorphic.auth.AuthenticationFilter</filter-class>
        <init-param>
            <param-name>authenticator</param-name>
            <param-value>authAdmin</param-value>
        </init-param>
        <init-param>
            <param-name>maxTries</param-name>
            <param-value>-1</param-value>
        </init-param>
        <init-param>
            <param-name>defaultLoginRedirect</param-name>
            <param-value>/index.jsp</param-value>
        </init-param>
        <init-param>
            <param-name>loginPage</param-name>
            <param-value>/auth/login.jsp</param-value>
        </init-param>
        <!-- Rules file is necessary when some files in a directory must not be authenticated,
             while the rest of the directory must be authenticated. -->
        <init-param>
            <param-name>rules</param-name>
            <param-value>
                ignore:#/isomorphic/*#
                match:#.*#
            </param-value>
        </init-param>
    </filter>    

    <filter-mapping>
        <filter-name>AuthAdminAuthenticator</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

admin.app.xml (admin is my app name)

<Application>
    <rpcBindings>
        <ServerObject ID="SecureAppDMI" className="it.zerob.admin.auth.SecureAppDMI">
            <visibleMethods>
                <method name="login"/>
                <method name="getUserInfo"/>
                <method name="logout"/>
            </visibleMethods>
        </ServerObject>
    </rpcBindings>
</Application>

secureAppDMI.java

/*
    Isomorphic SmartClient secure application DMI layer
    
    This class demonstrates DMI methods to develop SmartClient applications with
    authentication. The form-based authentication interface, located at
    isomorphic/login/iscAuth/*, relies on the server redirecting the client to various
    pages after login. The use of a DMI interface allows SmartClient applications
    fewer page transitions, greater flexibility, and a more seamless user interface.
    
    This authentication approach requires IDACall to be protected with AuthenticationFilter.
    To allow some IDACall requests to be authenticated but not others, it is suggested
    that a second IDACall mapping is created within the authenticated part of the site.
    See /WEB-INF/web.xml for more details.

server.properties

# -------------- SECURE APPLICATION EXAMPLE DEFINITIONS --------------------
authentication.enabled: yes

# superuserRole: If specified, user with this role will have access to all 
# dataSource operations regardless of the any requiresRole settings
#authentication.superuserRole: manager

authenticator.authAdmin: com.isomorphic.datasource.DataSourceAuthenticator
authenticator.authAdmin.datasource: TS_UTENTI
authenticator.authAdmin.usernameField: username
authenticator.authAdmin.passwordField: password
#authenticator.authAdmin.saltField: salt
authenticator.authAdmin.cookieDomain: .foo.it
authenticator.authAdmin.sessionTimeout: 1800

The login.jsp page is exactly as in the example folder.
When i try to access my index.jsp page the filter redirects me to login.jsp, the login dialog appears and here come the strange behavior:
- if i leave the login form empty and try to login the dialog simply disappears and i can see this in console:

=== 2014-09-06 20:29:27,208 [ec-7] DEBUG DataSourceAuthenticator - no user record for username: 
=== 2014-09-06 20:29:27,208 [ec-7] INFO  AuthenticationFilter - AuthAdminAuthenticator (realm: AuthAdminAuthenticator, securityLevel: 0) - Authentication failed, try # 0
=== 2014-09-06 20:29:27,208 [ec-7] DEBUG AuthenticationFilter - AuthAdminAuthenticator (realm: AuthAdminAuthenticator, securityLevel: 0) - ALLOWED access to public resource: /isomorphic/IDACall (matched by rule: ignore:#/isomorphic/*# located in: rules init-param in web.xml)

- the same thing happens if i write wrong user credentials

- if i write correct user credentials, in console i can read this

=== 2014-09-06 20:12:41,593 [ec-5] DEBUG DataSourceAuthenticator - datasource auth succeded for username: m
=== 2014-09-06 20:12:41,593 [ec-5] INFO  AuthenticationFilter - AuthAdminAuthenticator (realm: AuthAdminAuthenticator, securityLevel: 0) - Authentication attempt succeeded

subsequently the login dialog disappears but the browser is not redirected to the index.jsp and in the login method of SecureAppDMI "Authentication.isAuthenticated(context)" is false in any case.


how can i solve this ?
am i doing something wrong ?
