PPTP + MPPE

Hi,

we are migrating users of a Microsoft Forefront bases solution and i fail to get the VPN Stuff in place to work on the XG330.

I get it to work with RADIUS (NPS) against the Windows AD but i fail to get the MPPE going.

I have read about the

set vpn pptp authentication MS-CHAPv2 encryption SOME
set vpn pptp authentication MS-CHAPv2 encryption STRONG

The problem is that whenever i try to connect i can see this in pptpvpn.log

crauth_chap_verify called
crauth_pap_auth: REMOTE IP ADDRESS: '10.7.1.208'
MSCHAPV2 Received IP Address = 0xb1111ac
sent [CHAP Success id=0xfd "S=AAC47D3EEC080C045C3F6554EFF8EFDD31EA029F"]
MPPE required, but keys are not available. Possible plugin problem?
cr_ip_down notifier
Authentication server 127.0.0.1 gave logout response
sent [LCP TermReq id=0x2 "MPPE required but not available"]
rcvd [IPV6CP ConfReq id=0x5 <addr fe80::b85a:5408:4965:9ed5>]

Disabling MPPE by setting encryption to NONE lets users connect, which is not the desired solution. Any hints whats going wrong?
