Application Express :: Access Two Application With One Log In

Apex 4.1.1
Oracle 11g

I have two applications both in the same workspace. I want to log into one of them, but then have a link to a page in the second application, without having to enter a login to the second application.

Trying to follow the following from a while back, but cannot make it work in apex 4.1.1. Is it possible to access two application with one login? Both application are using the same ldap authentication.

I have both applications using the same get cookie process on page 101

{
declare
v varchar2(255) := null;
c owa_cookie.cookie;
begin
c := owa_cookie.get('LOGIN_USERNAME_COOKIE');
:P101_USERNAME := c.vals(1);
exception when others then null;
end; }

The link I use to the second application is a javascript pop window for displaying the second application and call it with the java pop up url

{
javascript:popUp('f?p=366:1:&SESSION.:::::')
}

However, it still asks me for the login to the the second application. I found other conversations that said to fill in the cookie name in the Session Cookie Attributes in Security, Authentication of the second application and entered the cookie name LOGIN_USERNAME_COOKIE here. However I still get the second application login screen now with a bunch of numbers in the username field.

What am I missing to get this to work without having to login again for the second application?
