APEX Pages - User Access List with NTLM

Question

Hi,
I'm building several APEX Applications, and using NTLM as its Authentication Scheme. With this, the users won't have to type any user and password. And their user name stated in top right screen.
I'd like to build another application to administer users of all created APEX Applications. So I'd like to build 3 tables:
1. users (hold user name, and user data)
2. pages (hold APEX Applications pages)
3. access_list (hold combined data of users and pages and access flag)
The last table will give me an SQL that can be used to create page level Authorization Scheme.
The problem is:
I cannot find a way to get a list of user ids to pre-populated the table users. Is there a way that an administrator user use an LOV of all NTLM user instead of typing domain\user to this application? OR is there a better and elegant way to create User Access List with NTLM.
Your helps will really help me, and thanks in advance.
Regards,
Aulia

This is kind of a followup to Scott's post. Instead of using your own tables to map user accounts to permissions etc, why not simply use LDAP to query the NT domain global catalog?
You can tell what users are members of particular AD groups and control access to functions based on AD group membership. Then you would only need one table that maps Apex functionality to AD groups.
That's what we do. Our account management people add users to different security groups and they get access to our apex app based on those groups. The type of access is controlled by the group to which they belong.
If you try to capture a list of all users, you'll be constantly trying to keep your list of users in sync with your AD/NTLM accounts.
Or I guess you could simply use LDAP queries inside the database to get a list of ALL your users in a nightly batch. Wouldn't help for people added in the middle of the day, but maybe that doesn't happen often in your company.
I have posted code on using Active Directory LDAP with dbms_ldap inside the database. Shouldn't be too much trouble to modify that code to scan your directory for users every night. Search for "dbms_ldap" in this forum.
