Created/Updated User in Apex 4.0 does not match valid application users

Question

We are working on a new install of Apex 4.0 - new application and seeing some odd values on the page details.
For many of the first pages in the application (1-20 and 101), click to get Page Attributes then the Name tab. The yellow box on the bottom shows each page as:
Created: 5 weeks ago - ADMIN
Updated: 10 months ago - <Name varies per below>
Pages 1/5 = DEMO
Pages 2/4 = SBKENNED
Pages 6-10 = SBKENNED
Page 20 = DPEAKE
Page 101 = MIKE
The rest of the pages have our normal developer and dates.
Not a huge deal, but looks very odd.

Answer 1

Custom Authentication is behaving like an End User account, which is good - no developer tabs at the bottom. I used something similar to Chapter 11 of the Advanced Tutorials guide:
CREATE OR REPLACE FUNCTION acl_custom_auth (
p_username IN VARCHAR2,
p_password IN VARCHAR2)
RETURN BOOLEAN IS
BEGIN
FOR c1 IN (SELECT 1
FROM acl_employees
WHERE upper(userid) = upper(p_username)
AND upper(last_name) = upper(p_password))
LOOP
RETURN TRUE;
END LOOP;
RETURN FALSE;
END;
