Just updated to latest intrepid updates (network-manager-pptp 0.7~~svn20081015t024626-0ubuntu1) and I still can't connect to any of my previous PPTP VPNs, no matter what I do with the password. Output of /var/log/syslog says this when connecting with password stored in the config:

Oct 28 10:24:26 zmog NetworkManager: <info>  Starting VPN service 'org.freedesktop.NetworkManager.pptp'...

Oct 28 10:24:38 zmog NetworkManager: <debug> [1225142678.628687] ensure_killed(): vpn service pid 16090 cleaned up 

And this when typed into a dialog box, which looks like a CHAP auth failure, except it isn't because the same user/pass works in Hardy:
