MPD pppoe access concentrator name and service name

[ovidiu ene]

I've been trying for a while to setup a mpd pppoe server to have a 
access concentrator name and a service name and is not working.
I understand that access concentrator name is given by hostname, but 
what about service name?
I've used pppoe server for a year now and at service name i have * 
wildcard. If i use set pppoe service "test" instead of "*" after i start 
mpd, from a windows client i cannot see the service. Any ideea howto fix 
that? I've googled for a while without success.

Best Regards
