Sorry, but I have to comment on this ;)
Although maybe popular, it leaves some security risks when used with PSK
(groups/passwords) without any further measures:
- it's possible you reveal not only your VPN-credentials but also your
Domain-password in one single step to attackers
- NT-Domain passwords are commonly weak and it's (by default) possible
to save them on the client giving you another risk

I'd use only certificates and/or one-time-passwords for VPN-access..

Still willing to take these risks, what Dave wrote should work fine.
