VPN 3030 concentrator fail to authenticate client if NT domain is set

[rman]

I'm using VPN 3030 Concentrator and Cisco ACS 2.6 NT as radius server.

I found that the CiscoSecure cannot authenticate Win98/ME VPN clients if the WindowsNT domain name is entered on the clients PC. The following error message was appeared on the client PC:

'Error 691. The computer U have dialed in to has denied access because the username and/or the password is invalid in the domain'

I checked the log on CiscoSecure and found that the login name is in the form "domain/username". The CiscoSecure reject the user with reason "CS unknow user".

What can I solve the problems ? Such as how to truncate the domain? or any VPN Concentrator software upgrade to do so ?

Thanks

You could use the strip realm option on the group setting under the General tab on the 3000.
