How to integrate a SSO based in cookie with ADF Security

Question

At work they asked me to integrate a existing SSO based in cookie with the new ADF + Jdeveloper 11g + WLS. After google for days and read a lot of blogs and official documentation I've made a custom LoginModule. I made it very simple, it's just an "if" inside the login() function with the username, if the username is "john" I put to the Subject some Principals. My steps are:
1- Create a new app based on "Fusion application" template.
2- Make a new ADF Taskflow with only one view inside (the entry point of the taskflow). The jspx only contains a welcome message.
3- Run the ADF Security wizard, all the steps with the default option, I don't change anything.
4- Put some users and some roles in jazn-data.xml, and maping them to an application role. Then I grant permissions to the application role to view the previous task flow.
At this point everything is ok. I run the taskflow and a basic login popup prompts me to write my username and password. Now I try to remove everything useless for me, like idstore, credentials, anonymous, etc. I only want a LoginModule that get the HttpRequest and passes it to an already done class that returns a true/false depending if the cookie is correct or not but, as I said before, my LoginModule is so simple now and even didn't try to do something more complicated than an if. The steps I try are:
in jps-config.xml
5- Remove idstore.xml and credentials.
6- (loginmodule tab) Make a new login module, and put here my class. The class is in the ViewController project and JDeveloper find it navigating through the heriarchy, so I have visibility. I put REQUIRE flag, add all roles and debug mode.
7- In the security context unmark the idstore.loginmodule and mark myLoginModule. Also delete the anonymous security context.
All that I got until now is a 500 error (Internal server error - Authorization Exception). Sometimes (the close i've ever been to do something correct) the browser ask me for user/password but then only recognizes the users that already are in WLS (idstore from previous tests), but NOT the "john" user that is inside my custom LoginModule. Even more, if I run the WLS from JDeveloper 11g in debug mode, the runtime never stops at breakpoints inside my custom login module. It seems that my LoginModule isn't deployed or I made some error maping the roles.
So, my questions are:
- I'm in the good way? If I want an authentication based in cookie/httprequest I have to do a custom LoginModule? My goal is to do a re-usable code, and re-use the code that my co-workers have done. They have a class that with only the HttpRequest determines if a user is logged or not.
- If I'm in the good way... how can I put my custom LoginModule in the WLS? I tried to search something in the Administration Panel (localhost:7101/console) but I did'nt find nothing.
- In case I'd got the custom LoginModule working fine in WLS... how can I get a HttpRequest from a LoginModule and avoid the username/password dialog? I've to make a filter and pass it to the my LoginModule? If it's correct... how?
I don't post my code because is so simple, it's based on DBTableLoginModule but without all the database access code.
Thanks to all!

Hi Frank,
Thanks a lot for your answer. Just one more easy question: what I need to do is a custom Authentication Module (which will read the cookie)? If only you can point me to the correct chapter of the WLS documentation I'll be very pleased.
In future releases of JDeveloper will be easier to do this kind of things related to security?
