Apps 11I - Apex Integration

Question

I'm in the process of attempting to prove out to my business community that Apex can be integrated with the E-Business Suite. Current env is 11.10.5.2 linux, with 10.2.0.4 on single tier. I've installed apex to the database without issue. I've followed the notes found on the web for the DAD & httpd.conf, as well as metalink note :373604.1 to allow authentication against an E-Business Suite user.
My problem is two fold :
Currently, when attempting to access the pls/apex/apex_admin uri for the first time, I am prompted for a username / password. after several attempts, i finally hit on the apps/apps-pwd combination that works. Once into the workspace, i have configured the authentication against the fnd_web_sec procedure. However, any attempt to authenticate against and E-Business user receives the dreaded invalid credentials. I should also say that i have the workspace_schema parsing as the apps schema in the database.
Below is my DAD configuration :
DAD_apex]
connect_string = TEST
password = ap3x
username = APEX_PUBLIC_USER
default_page = apex
document_table = wwv_flow_file_objects$
document_path = docs
document_proc = wwv_flow_file_mgr.process_download
reuse = Yes
enablesso = No
stateful=STATELESS_RESET
nls_lang = American_America.UTF8
custom_auth = Basic
Any help would be greatly appreciated.
Thanks

Thanks Kofi,
Here is the authentication procedure I'm using. It is currently owned by apps with execute to the XX_APPS schema ( apex custom schema). With a synonym created by the xx_apps schema. There was a white paper from one of the OUAG conferences by Rod West that stated to ensure the custom schema in Apex was parsed as apps. That way to have visibility. Based on our plan, end users would have no access to developing their own reports.
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;
We've defined the custom authorization scheme with the "return ebiz_suite_auth;" function.
Thanks
James
