Problem with PPP configuration

[icsedp at omniway.sm (EDP- Department Istituto Credito Sammarinese)]

Hello,
my internet provider is changing the way to access his system.
We have a static IP address and I'm connecting using a linux server with PPP.
With the new access I need to use PPP with CHAP but when I try to access the server I can't have a succesfull connection.
I used the /usr/ppp-on script and modified /etc/ppp/ppp-dialer script eliminating the login,password requests.
Anybody can help me with an example of /etc/ppp/chap-secrets and/or script files.
Here is my /etc/ppp/chap-secrets file :
me		int-prov		"my-passwd"
int-prov		me		"my-passwd"

I modified the /etc/ppp/options file adding "auth"

Thanx
