Oh OK.., now i get it: In Basic Auth-Scheme, the Useragent -after getting the
required user and pass info from Client- resends his Authorization-String in every
Requestheader
submitted to the Server. So the webserver have not to recognize an already authorized
user,
as long as he's possible to authorize the user on every request.
So there's no way, to use an http-form instead of browser's ugly authorization-box and
perfrom the
Basic Authorization (without Cookies or taking an sessionkey with the url)?

I supposed the browser to resend always an unique "bowser session id", which
is used by apache to save certain values, like $ENV{'REMOTE_USER'}
(similiar to a session-cookie with uid and serverbased $vars) ..
Isn't this the way Basic Authentication scheme works ? ..
[QUESTION] Can't read out verified username (auth)
Hi,
i was writing my own AuthHandler with modperl v2 (v1.99_09).
Getting the Username/Password-Pair from an html-form (submit via post) and finally
checking it against an mysql-table works fine so far.
When the authentification have taken place.. the username should be reminded
in any way, so the user haven't to enter their password-info on every request... and
this is
what doesn't work in my code:
--- /usr/lib/perl5/site_perl/5.8.0/MyIntranet/AuthHandler
package Myintranet::AuthHandler;
use Apache::Const qw(OK FORBIDDEN AUTH_REQUIRED SERVER_ERROR);
use Apache::RequestRec;
use Apache::Connection;
use Apache::compat;
use Mysql;
use strict;
sub handler {
my $obj = shift;
return OK if ($obj->user);
my %params = $obj->content();
[..]
$obj->user($params{'user'});
return OK;
}
--- EOF
After having entered user/pass via html-form, this authentification does his job well,
but on the following request
(on same browser) $obj->user doesnt seem to return any value.. so this handler tries
to compare http post data (
which arent present this time) with userdata in mysql-table.. resulting in an
Auth_Required error.
Any logical misstake doing this way of "reauthorizing" .. or anything missing ?
Available documentation - modperl cookbook included - does it that way ...
Thanks for help/any hints!
