How to enable PPTP encryption in VPN3005 and Active Directory environment.

Base on cisco's tech tips, pptp encryption isn't supported in NT Domain.

Anyone know what is the workaround?

I have a AD and my users want to remember just one password. So I need to have the VPN3005 to authenticate users thr the AD. But it won't work unless I disable PPTP encryption (unacceptable of coz).

I tried to use L2TP/IPSec, that solved the problem, but then users behind their D-link or any other NAT device at home can't connected, which i understand is a NAT/IPSec chicken'n egg problem. So I have to roll back to PPTP for universal deployment.

I is such a common issue I would think somebody would have a solution, right?

L2TP over IPSEC is a much better solution. The 3005 supports NAT Transparency mode which will allow your users behind NAT to get in. Cisco’s TAC can walk you through it if you need.
