Problems with custom authentication module

["Hann, Brian" <Br...@umb.com>]

Hi,
 
I'm writing my own authentication module that uses Oracle and special
encryption to handle passwords, it uses pretty much the same code as
AuthDBI except for a few changes.
 
Everything was running smoothly until I tried to make a mod_perl handler
be the 401 ErrorDocument.  If I do that, the authen handler returns 401
on every request and the 401 page is displayed without ever popping up
the auth box.  If I make the 401 ErrorDocument a regular HTML page, I
will get the 3 chances at the popup box unless I do not send across a
username and in that case it goes straight to the 401 page (possibly a
problem with my code).
 
HOWEVER, if I use an htpasswd file to do authentication and set the
mod_perl handler to the 401 page, it works perfectly.
 
Can anyone tell me where I might be going wrong?  I'm having a hell of a
time tracking this one down.
 
Thanks,
