Hi there,

can anybody help me with the following problem:

I use a cisco7200 with a 3des-ios and authentication and authorization via
radiator. Without encryption everything is going well. I use the following
user file:

test    User-Password = "test"
        MS-MPPE-Send-Key = "",
        Service-Type = Framed-User,
        Tunnel-Type = PPTP,
        Tunnel-Medium-Type = IP,
        Tunnel-Server-Endpoint = 10.10.10.254,
        Framed-Protocol = PPP,
        Framed-Netmask = 255.255.255.0,
        Framed-Routing = None,
        Framed-MTU = 1500

When I configure on my win98 under server-types: 'require data encryption'
the debugging output from the cisco is the following:
...
Mar 30 17:18:00 ... Vi2 MPPE: don't understand all options, NAK
Mar 30 17:18:00 ... Vilast message repeated 1 time
Mar 30 17:18:00 ... Vi2 MPPE: RADIUS keying material missing
...

The last line I got even without encryption.

The same result I got with several tests with 
ppp encrypt mppe auto stateful
ppp encrypt mppe auto required
ppp encrypt mppe auto passive
ppp encrypt mppe 40
ppp encrypt mppe 128 
on the cisco box.

The radiator debugging output says everythings is ok:
...
*** Sending to x.x.x.x port 1645 ....
Code:       Access-Accept
Identifier: 30
Authentic:  5<151>W<242>&V<140>8<0><0><0><0><0><0><0><0>
Attributes:
        MS-MPPE-Send-Key = "<169>a<224><152><155><134><189><220><238>K<148>,<19"
        Service-Type = Framed-User
        Tunnel-Type = PPTP
        Tunnel-Medium-Type = IP
        Tunnel-Server-Endpoint = "10.10.10.254"
        Framed-Protocol = PPP
        Framed-Netmask = 255.255.255.0
        Framed-Routing = None
        Framed-MTU = 1500
...

What expect the cisco from radiator when it says:
RADIUS keying material missing ??
Does it mean 'MS-CHAP-MPPE-Keys' and how is the syntax in user file?

Thanks,

Rolf
