IAP Roaming with 802.1x cert and OKC

    Hi Folks,

    I'm having some wierd issues with my IAP cluster.

    CASE: 16 IAP's version 6.4.2.0-4.1.2 in one cluster on same broadcast domain (natvie vlan in trunks to AP, but management vlan for the network.) Differents SSID tagged to different VLAN, on same switch (cabled clients is also in this VLAN no problems when clients is on cable.)
    I have 2 SSID-Profiles and 2 laptops.

    Corp laptop; HP win8.1 with intel 7260 AC nic
    Corp laptop; HP win7 with intel xxxx N nic


    The issue:
    HP win8.1; When assoiated to "Some-WiFi" the computer is getting right IP address and low ping and good SnR, everything is good. But when I'm trying to move around in the office, the PC suddenly gets a APIPA address (169.254.x.x) but still assoitated to the SSID. - If the PC has a static IP address assigned to the NIC, and roaming, no problems.

     

    HP win7 have no problems roaming in the building, however often low bandwith, but never APIPA IP.

     

     

    Bonus: NPS server always replay audit success when clients validating with valid certificate.


    Log from IAP cluster on win8.1:

    Any ideas why my Win8.1 cant roam with 802.1x but my Win7 can?
