Cisco Wireless and Server 2008 NPS RRS feed

  • Question

  • We are using WLC4402 for our Aironet 1240AG access points.  The clients are connecting to the access points and are authenticating to the RADIUS server.  I am seeing the logs in Server 2008 but they are being rejected due to Network Policy on the NPS server.


    In order for the clients (authenticated via Active Directory user) I have to set the Authentication in the NPS Connection Request Policy to "Allow clients to connect without negotiating an authentication method". 


    I do not have a certificate on the server and my method options are MS-CHAP-v2, MS-CHAP, CHAP, PAP, SPAP, and allow without negotiating.  This RADIUS server was moved from Server 2003 IAS to Server 2008 NPS and there were no issues in Server 2003 IAS.  I have all authentication methods allowed and it still gives me the error below.  Only when I check "Allow clients to connect without negotiating an authentication method" it allows the authentication to proceed. 


    Any insight is greatly appreciated.  Thank you!

  • Hi,

    The problem might be in network policy (named Wireless MAC Authentication Policy), not connection request policy.

    How do you have this policy configured?

    Have you tried running the wizard in NPS to create wireless policies? See http://technet.microsoft.com/en-us/library/ff919513(WS.10).aspx.

  • I have not but I will give it a try.  As of right now it seems to be working but I have to leave the "Allow clients to connect without negotiating an authentication method" checked.

    Thank you for the reply!
