I upgraded the VPN 3005 concentrator to 4.01 today and had to downgrade within an hour due to RADIUS authentication problems for users connecting using Microsoft UPN names e.g. [email protected]
The Concentrator config is that we have a Group setup "whatever.com" that sends all the authentication requests to Windows 2000 IAS (RADIUS).
Before the Upgrade, in the IAS Log files the Username sent from VPN to IAS was the actual name as [email protected]
After the Upgrade any user using the UPN form was unable to connect. The IAS log files showed that VPN was sending the Username as only joe.billy and "@whatever.com" part was truncated, which resulted in Authentication failures. Any user using WHATEVER\jbilly worked ok...
Have anyone else seen ths behaviour ?
Should i have configured something in the VPN after upgrading it ?
(In Group-->general Properties, i DID have the Strip Realm box UN-CHECKED).
