problem with pptp, using mpd

[Mathieu L.]

Hello, 

I am having trouble using mpd, I want to connect to a vpn with pptp
(vpn service provided by relakks.com).

Here is my configuration:

mpd.conf:
#########################

default:
	load relakks

relakks:
        create bundle static B1
        set iface route default
        set ipcp ranges 0.0.0.0/0 0.0.0.0/0
# Enable Microsoft Point-to-Point encryption (MPPE)
        set bundle enable compression
        set ccp yes mppc
        set mppc yes e128
        set bundle enable crypt-reqd
        set mppc yes stateless

        create link static L1 pptp
        set link action bundle B1
# Enable both sides to authenticat each other with CHAP
        set auth disable internal
        set auth authname "lejatorn"
        set auth password "XXXXXXXX"
        set link no pap
        set link no eap
        set link yes chap
        set link mtu 1460
        set link keep-alive 10 75
        set link max-redial 0
# Configure PPTP and open link
        set pptp peer pptp.relakks.com
        set pptp disable windowing
        set link enable incoming
        open


and here is the output when I start mpd5:

It seems that the authentication is failing but I don't know why as
the login and password are correct (I tested them with pptp/pon on
Debian, it worked fine). One thing that puzzles me is the 
[L1]   Name: "localhost"
line, as if "localhost" was used as a login or something...

Can anyone help please?

Mathieu
