Oracle Apex Authentication with EBS

Question

Hello ,
My name is Ramiz.
I have Oracle Applications EBS suite with 10g and Oracle Apex on seperate 10g.
Now, I am trying to use same user-id and password of EBS to login into Oracle Apex. I have performed following steps from this url.
(http://skrajend.blogspot.com/2007/06/htmldb-authentication-with-oracle.html)
1. I have dblink between two database nodes (i.e. EBS database and Apex database )
2. I have created following function as well on EBS database.
====
SQL> create or replace function ebiz_suite_auth (p_username IN VARCHAR2, p_password IN VARCHAR2)
return boolean
as
begin
if fnd_web_sec.validate_login(p_username, p_password) = 'Y' then
return true;
else
return false;
end if;
end;
====
2. Now in second step from above url , Author is granting execute priv to
user "HTMLDB" like following
SQL> grant execute on ebiz_suite_auth to htmldb;
But , my question is that Apex is installed on different 10g so in above
execute statement which user should I give execute to ? Do I have to create same user of Apex in EBS database and give exec priv ? but than how does it going to talk to EBS database ?
3. I have created the Authentication Scheme as the steps described in the above url.
=================
2nd approach which is same as above except but here user is not giving
any exec priv
===============
create auth function ( as above)
Create a new Authentication Scheme
•Select From Scratch
•Enter a Name
•Leave Sentry Functionempty
•Leave Session Verification Functionempty
•Set Invalid Session Target= ApExBuilt in Login Page
•Leave Pre-Authentication Processempty
Select Use my custom function to authenticatefor
the Credentials Authentication Method and enter
return custom_ebiz_suite_auth;
for the Authentication Function
•Leave the Post-Authentication Processempty
•Leave all Cookie Informationempty
•Enter
wwv_flow_custom_auth_std.logout?p_this_flo
w=&APP_ID.&p_next_flow_page_sess=&APP_ID.:
1:&SESSION.
for the Logout URL(all on one line)
•Create & Activate your Authentication Scheme
I performed 2nd approach too but it doesn't work for me because
my Apex is installed in seperate 10g and EBS is in sperate 10g. 2nd approach is from a perosn name SCOTT.
