http 401 error and follow-up apache mod_auth_ldap

[adfundum@dds.nl]

Hello y'all

I have Apache and PHP4 very well running with auth_ldap.
(www.rudedog.org)

But if users log in, I want to use their login names. So I
try to make a Error-401 php-page, to pop-up when a user
points to a secured directory. whne the user hits the
'submit" button, I want (the browser???) to store the uid /
passwd cobination, for later re-use.

How?

Thanks
