Cisco VPN Client: Radius Authorization
|
|
Hi,
I want to authorize VPN Client to make connection to PIX515 only from one specific outside public IP address. (In my LAB test it means AV pair ip:source-ip=192.168.2.10)
Client try to connect, Xauth window appears on Windows machine, client write right username and password, but connection is not succesfull. Reason on ACS (windows 4.0) in failed attempts log is "CS password invalid".
After removing requirement for authorization from "tunnel-group VPN-SUPPLIERS general-attributes", connection is successful. Interesting is, that there is one passed authentification and one failed in the ACS logs for this one connection. You can also see in full debug, that user (vpn1) is authentificated twice during connection, once successful and once not.
Also, in the debug, there is not authorization request, only authentification request. But it fails on that athentification request.
More details:
1. Tunnel group configuration for required authorization: (authorization-required command)
tunnel-group VPN-SUPPLIERS general-attributes
authentication-server-group (outside) VPN LOCAL
authorization-server-group (outside) VPN
accounting-server-group VPN
default-group-policy VPN-SUPPLIERS-POLICY
nac-authentication-server-group VPN
password-management password-expire-in-days 1
authorization-required
