vpn connetion fails on lenny

Hi all

I'm using debian lenny and I've created a vpn connection (client) to connect to a windows vpn server , my chap-secrets file looks like the following :

# Secrets for authentication using CHAP
# client server secret IP addresses

........

# added by pptpsetup for afa
afa afa "my_pass" *


and my settings for 'afa' vpn connection are :

# written by pptpsetup
pty "pptp 212.50.246.113 --nolaunchpppd"
lock
noauth
nobsdcomp
nodeflate
name afa
remotename afa
file /etc/ppp/options.pptp
require-mppe-128
ipparam afa


options.pptp file looks like this :

# Lock the port
lock

# Authentication
# We don't need the tunnel server to authenticate itself
noauth

# We won't do PAP, EAP, CHAP, or MSCHAP, but we will accept MSCHAP-V2
# (you may need to remove these refusals if the server is not using MPPE)
refuse-pap
refuse-eap
#refuse-chap
#refuse-mschap

# Compression
# Turn off compression protocols we know won't be used
nobsdcomp
nodeflate

# Encryption
# (There have been multiple versions of PPP with encryption support,
# choose with of the following sections you will use. Note that MPPE
# requires the use of MSCHAP-V2 during authentication)

# http://ppp.samba.org/ the PPP project version of PPP by Paul Mackarras
# ppp-2.4.2 or later with MPPE only, kernel module ppp_mppe.o
# {{{
# Require MPPE 128-bit encryption
require-mppe-128
# }}}

# http://polbox.com/h/hs001/ fork from PPP project by Jan Dubiec
# ppp-2.4.2 or later with MPPE and MPPC, kernel module ppp_mppe_mppc.o
# {{{
# Require MPPE 128-bit encryption
#mppe required,stateless
# }}}


when I try to connect using "pppd debug call afa" , I get this log and debug messages :

    Were you able to connect to the server in the past with this configuration file?
    Have you verified that the authentication mechanisms in use are properly configured on your system?
