I am using Liferay 6 for development , i have developed Liferay6 Struts2 Portlet and deployed .
Using Custom JSPs Hooks , i have overridden the $PORTAL_ROOT_HOME/html/portlet/login login.jsp and created
my own jsp page as shown 

<HTML>
    <HEAD>
        <TITLE>Login using jsp</TITLE>
    </HEAD>
    <BODY>
        <H1>LOGIN FORM</H1>
            <form>
                <table>
                    <tr>
                        <td> Username  : </td><td> <input name="username" size=15 type="text" /> </td> 
                    </tr>
                    <tr>
                        <td> Password  : </td><td> <input name="password" size=15 type="text" /> </td> 
                    </tr>
                </table>
                <input type="submit" value="login" />
            </form>
    </BODY>
</HTML>

    You might have got a solution by this time. If not, you can try the following.

    I believe you are trying to override the login portlet of liferay. In that case there are 2 ways you can handle this login mechanism.( make sure that the same name is given to input fields as liferay’s login page has)

    1. Extend the liferay’s LoginAction class. You have to write an ext plugin or if you are using 6.0 SP2 or 6.1 you can use a hook to extend LoginAction class. Refere mika’s blog http://www.liferay.com/web/mika.koivisto/blog/-/blogs/7132115

    2. Write your own class which should implement liferay’s Authenticator interface and you have to override 3 methods of Authenticator interface.

    For example if you are overriding authenticateByEmailAddress(….), you have to return a SUCCESS(1) or FAILURE(-1). I believe the 2nd and 3rd parameters of the method are user id and password that are entered on the screen. please refer liferay source.

    In order to bypass liferay’s default authentication mechanism, give the following configuration on the portal-ext.properties auth.pipeline.pre=your.package.your.class

    Still liferay check against its own database. To avoid that add following configuration on portal-ext.properties.

    auth.pipeline.enable.liferay.check=false.

    So you have your own custom authentication where you can authenticate against your own database or what ever mechanism you want.

    Hope this helps
