[pptp-server] CHAP authenticates ok... now what?

    I successfully install pptpd on my RedHat 7.2 machine...  I added an account to chap-secrets, and  set pptpctrl to work from xinetd without a problem.  From my Win2K box, I configured the VPN.  I get a seuccessful authentication, and then it just stops.  Isn't it supposed to, well... DO something to complete the connection after authentication???

Can someone help me figure out what's going on?

Thanks,
  Issac
