Automatically Log In to APEX from another site

Question

Check out this code:
<FORM method="POST" action="http://whatever.com:1234/pls/apex/wwv_flow_custom_auth_std.login">
<input name="p_flow_page" type="hidden" value="104:1">
Username: <input name="p_uname" type="text" value="yourusername"><br>
Password: <input name="p_password" type="password"><br>
<input type="submit" value="Login to APEX">
</FORM>
If you save this code on any website (even on a different server), people can use the form to log into your APEX application.
The problem though, is when you change your Authentication Scheme to something other than the default.
I'm using a custom Auth Scheme, and it works great for normal logins, but it unfortunately breaks the above code. Anyone have any ideas on what to change in the above HTML to fix this?

Scott,
I'm using APEX v3.0.0.00.20
My custom auth scheme uses an Authentication Function that returns a boolean.
Under "Authentication Function" on the Authentication Schemes Page, I have:
return apps.validate_login_bool
which basically checks if the user/pass is in my custom table. No other changes were made to the login page.
The custom auth scheme works (meaning it only lets people log in if they use their user/pass from my custom table), but only if they go to the APEX login page, and manually type their credentials.
If a user uses the HTML form above to login, they are brought to the URL http://whatever.com:1234/pls/apex/wwv_flow_custom_auth_std.login, which shows a pure white page, regardless of whether they use a valid username/password to login.
