[Icecast] url authentication problems

[Klauss Fumuldavijus]

strange processes are happening while trying to authenticate via url using (icecastauth-examle-1.0)
i'm using user "test" and password "test". I'm opening http://10.10.10.10:8000/Test.m3u with winamp 5.1. 
This user(test) exists in mysql database, and action.php suscessfuly extracts that user from database.

here's what I receive in icecast error log:
2006-01-29  15:32:30] INFO auth_url/url_add_client client auth (http://10.10.10.10/auth/action.php) failed with ""

and apache's httpd-error.log says:
[Sun Jan 29 15:32:30 2006] [error] [client 10.10.10.10] user  not found: /auth/action.php
[Sun Jan 29 15:32:30 2006] [error] [client 10.10.10.10] user test not found: /auth/action.php

it is strange that "" (empty) user also seems try to authenticate.

below is the dump of tcp session:
_____________________________________________
GET /Test HTTP/1.0
Host: 86.38.25.21
User-Agent: WinampMPEG/5.1
Accept: */*
Icy-MetaData:1
Authorization: Basic dGVzdDp0ZXN0
Connection: close

HTTP/1.0 401 Authentication Required
WWW-Authenticate: Basic realm="Icecast2 Server"

You need to authenticate

i've also tried testauth.php with action "listener_add"
here's it's dump:

this session looks ok, but i don't understand how to start streaming after this procedure? testauth.php is just something like query parser?isn't it?

my icecast.xml portion:
_____________________________________________________________
<mount>
<mount-name>/Test</mount-name>
<authentication type="url">
<option name="listener_add"    value="http://10.10.10.10/auth/action.php"/>
<option name="listener_remove" value="http://10.10.10.10/auth/action.php"/>
<option name="mount_add"       value="http://10.10.10.10/auth/action.php"/>
<option name="mount_remove"    value="http://10.10.10.10/auth/action.php"/>
</authentication>
</mount>
