XP(pptp)--->NSM--->FreeRadius--->eDir = NOT WORK :(

I use NW6.5Sp5 with eDir8.7.7
Install on the SLES9 FreerDaius with integrate for work with eDIR:
[url]http://www.novell.com/documentation/edir_radius/index.html[/url]
From the SLES9 with Freeradius i can do this:
radtest userpptp1 qwerty 192.168.252.117:1812 1812 qwerty
Sending Access-Request of id 69 to 192.168.252.117:1812
User-Name = "userpptp1"
User-Password = "qwerty"
NAS-IP-Address = proxy2
NAS-Port = 1812
rad_recv: Access-Accept packet from host 192.168.252.117:1812, id=69,
length=32
Framed-IP-Netmask = 255.255.255.0
Framed-IP-Address = 10.221.228.6

After this go to the my NSM, enable use Radius: 192.168.252.117 server.
Eenable Use PPTP on the NSM: Network | PPTP VPN Access
Encryption: Strong
Authentication: Radius Database

After this go to the my XP_Proof_SP2 and create new Connection (Type VPN =
PPTP VPN)
And can not UP connect to the PPTP SERVER (192.168.252.100) with account:
userpptp1 / qwerty
In the Log-file on the FreeRadius Server always see:
Packet-Type = Access-Request
Sat Oct 14 10:34:05 2006
Service-Type = Framed-User
Framed-Protocol = PPP
User-Name = "userpptp1"
MS-CHAP-Challenge = 0xf9b608a35a0208679af44b1978a9c998
MS-CHAP2-Response =
0x4000352ddc26976caa8fe8c56e636a160283000000000000000083ec22cdd677bbc01238cf09c811c5a343bdaca6074023fd
Calling-Station-Id = "172.16.16.250"
NAS-Identifier = "pptp"
NAS-Port = 0
NAS-IP-Address = 192.168.252.100
Client-IP-Address = 192.168.252.100

What can i do for resolver this problem ??
