IAS and Freeradius

[Artur Hayne]

HI,
 
 The freeradius is comunicate with the IAS through a proxy, but dont authenticate.
 The windows show me this error:
 
 "Event type: Error
 Source: IAS
 A malformed request was received from client XXXX. The data is the packet."
 
 The freeradius debug:

  Waking up in 1 seconds...
  rad_recv: Access-Request packet from host 10.2.1.XX:33634, id=206, 
 length=200
  Ignoring duplicate packet from client OpenSER:33634 - ID: 206, due to 
 outstanding proxied request 1.
 
 What is worng? I dont undestand: freeradius and IAS use the same protocol... It is attribute question? Cryptografy?
 Please any Idea...  a tip
  anybody already had some similar experience?
 
 I tried in some ways:
 
 |Openser| -> |Freeradius| -> |AD|
    |Openser| -> |Radiusclient| -> |IAS| -> |AD|
    |Openser| -> |Freeradius| -> |IAS| -> |AD|
 
 help!
 
 thanks...
