Supplicant doesn`t pop up on Win XP during authentication wth Cisco ISE

[ToX1c1986]

Hello!

I try to configure 802.1X authentication with Cisco ISE, Win XP SP3 and native supplicant.

Problem is that when workstation connects to the network, it uses  hostname as an username and sapplicant doesn`t pop up to ask me  username and password. Anybody know how to resolve this problem? Mb to  install some patch on Win XP?

Thank you!

BR,

Max

Did you configure the suplicant to do a user-based authentication? And to not use the login-information from Windows for logging into the network? That has to be configured in the suplicant.

Thanks for reply!

Yes only for user-based authentication, I de-select "Validate server certificate" and "Automatically use my Windows logon name and password (and domain if any)". After shut/ no shut swith port I don`t see dialog box which asks credentials.

In ISE log I see that workstation uses it`s hostname as an username and uthentication fail.

Did you try to logoff and login after enabling the supplicant. If you are sending the machine credentials then you may want to check the registry settings:

Tarik, yes of course. Also I manually installed Cisco NAC agent on workstation and it also don`t ask credentials.

I read this article, but I don`t understand what should I do?

In RADIUS debug I see folowing:

RADIUS(000000F7): Send Access-Request to ISE:1812 id 1645/243, len 248

RADIUS:  User-Name           [1]   29  "host/ISEfuji.office"

RADIUS:  NAS-Port-Id         [87]  22  "GigabitEthernet1/0/1"

RADIUS:  NAS-IP-Address      [4]   6   192.168.244.252

Why User-Name is workstation hostname I don`t understand.

Hi,

The NAC agent in an ISE deployment doesnt prompt users for authentication (that was done from the Clean Access Server in the Nac appliance days).

However, it looks as if the machine credentials are being sent instead of the user credentials. Have you tried to restart the wired auto config settings? Also have you checked the event veiwer on the workstation to see if there are any errors for the eap host? Also try seeing if the network driver needs an update.

Thanks,

Tarik, do you mean stop/start service? If yes, I tried it several times. In event veiwer I see folowing:

Network authentication attempts have been temporarily suspended on this network adapter.

Network Adapter: Realtek RTL8139 Family PCI Fast Ethernet NIC - Packet Scheduler Miniport

Interface GUID: b9f134f3-3e02-4067-bba7-d090c0fd3fb8

Reason Code: 327685

Length of block timer (seconds): 1200

Now I`m trying to find driver update.

I ran into a very simliar problem with this, can you try to run the "diagnose" option on the network adapter and see if this fixes your issue?

Thanks,

Tarik, do you mean right-click mouse on LAN and choose "diagnose"? I do it, but problem still exist.

I find new version of driver 6.110.1029.2008, is update help me?

Please post screenshots of your xp settings for eap. Are you forcing the client to use the windows single sign on?

No,I`m not.

Tarik, that is screen in attach, but I have Win XP Russian Edition, I hope you'll understand anyway.

[Tarik Admani]

In the 3rd screenshot can you check that box and see if it sends the credentials through.

Thanks,

Tarik, unfortunately I don't understand how to do it, could you explain me what should I do?

[Tarik Admani]

In the screenshot on the very right that you provided just check that box, from the english version this looks like the windows single sign on option.

Thanks,

Tarik, in Russian version if checkbox is selected, it means that the username and password are automatically selected from AD. That is the credentials with which the user connects to his workstation. I don't know if it can help us to solve the problem but Web Auth works fine.
