[Icecast] URL authentication

[Peter Bengtson]

I can't get URL authentication to work. The notification script is  
never called by icecast (v 2.3.1).

This is the mount point:


>     <mount>
>         <mount-name>/tp.mp3</mount-name>
>         <max-listeners>499</max-listeners>
>         <hidden>1</hidden>
>         <no-yp>1</no-yp>
>         <authentication type="url">
>             <option name="mount_add"       value="http:// 
> wherever.tld/radio/notify.php"/>
>             <option name="mount_remove"    value="http:// 
> wherever.tld/radio/notify.php"/>
>             <option name="listener_add"    value="http:// 
> wherever.tld/radio/notify.php"/>
>             <option name="listener_remove" value="http:// 
> wherever.tld/radio/notify.php"/>
>         </authentication>
>     </mount>
>

This is what appears in the error log when a client connects:

> authentication

All clients are added as authenticated, but the log files on  
"wherever.tld" show that no access has been made.

I have scoured the forums and the mailing list archives for answers -  
every single page - and nobody has ever come up with a really good  
explanation for this. WinAmp and password buffering have been  
mentioned, but WinAmp is not running, has not been running, nor will  
it ever be running, so there is no chance of password buffering.  
Indeed, no passwords have yet every been passed with a client  
connection. And this shouldn't in itself inhibit authentication.

It is difficult not to suspect an icecast 2.3.1 bug, but I'm still  
hoping it is some sort of XML typo or unannounced spec change.

I would be most grateful for any help or ideas. Thanks in advance,
