Custom logon module not called by the portal

Question

Hi, all.
I need some help urgently on this new portal requirement. There are some sensitive ESS/MSS iviews that we need to give the users an additional logon challenge. The normal ESS/MSS iviews will be using SSO. This one will still use SSO, but have to pass the userid/password challenge.
We have decided to use the authentication scheme. Also, the "form" logon stack has been modified with only one logon module, which is our customized one. To create the java project, jar and library, we are following the link: http://help.sap.com/saphelp_nw04s/helpdata/en/46/3ce9402f3f8031e10000000a1550b0/frameset.htm
Here's the extract of our authscheme.xml:
        <authscheme name="certlogon">
            <authentication-template>
                client_cert
            </authentication-template>
            <priority>21</priority>
            <frontendtype>2</frontendtype>
            <frontendtarget>com.sap.portal.runtime.logon.certlogon</frontendtarget>
        </authscheme>
        <authscheme name="coo_secure">
            <authentication-template>
                form
            </authentication-template>
            <priority>40</priority>
            <frontendtype>2</frontendtype>
            <frontendtarget>com.sap.portal.runtime.logon.basicauthentication</frontendtarget>
        </authscheme>
        <authscheme name="basicauthentication">
            <authentication-template>
                ticket
            </authentication-template>
            <priority>20</priority>
            <frontendtype>2</frontendtype>
            <frontendtarget>com.sap.portal.runtime.logon.basicauthentication</frontendtarget>
        </authscheme>
The authscheme is called coo_secure. When a user clicks on the iviews with the coo_secure authscheme, a userid/pwd prompt pops up. But it does not accept whatever I type in. From the defaulttrace, I do not see any hint that our customized logon module was ever called.
Is there anyway to turn on portal tracing to see what is going on?
Thanks,
Jonathan.

Hi Jonathan,
Did you solved the problem with the custom logon module?
We have a very similar scenario. I followed below help site to implement a custom logon module for particular iviews.
http://help.sap.com/saphelp_nw70/helpdata/EN/54/f91fba71ae48309e4267b4a36fa47b/frameset.htm
and also the documentation:
SAP Netweaver Developers Guide - Integrating Security Functions
But I am not able to get my own custom login module with the custom authscheme running.
If I access my specific IViews that requires additional custom authentication I get the portal login page again. After giving login data I get the error message:
Java iView Runtime
An exception occured while processing your request.
If this situation persists, please contact your system administrator.
If you solved your problem, can you please share the solution with me?
Thanks,
Regards,
Yasar
