VPN Client password expiry with IOS?

desmckee · ‎04-16-2007

Hi,

I've been reading about the password expiration feature for the VPN Concentrator using Radius to a MS server:

http://www.cisco.com/en/US/customer/products/hw/vpndevc/ps2284/products_configuration_example09186a00800946b9.shtml

Does anyone know if this feature can work if an IOS router is terminating the remote IPSec and using Radius to authenticate the VPN client users? Or is the VPN Concentrator using some Radius extensions behind the scenes to support this feature?

Has anyone enabled password expiry in another way using

Thanks,

Des

Use the command password-management password-expire-in-days on LDAP server. There is a new authentication server choice in the 3.6 code called "RADIUS with Expiry". You would need to setup a RADIUS server to allow

the concentrator to query it, and then set the RADIUS server to pass off the query to the NT Domain server. Then under the VPN "Group" that the clients connect to, you would select the "Authentication" method as "RADIUS with Expiry". You would also need to create a RADIUS server account in the concentrator telling it about the RADIUS server it will query. So to get this to

work, we can't have the concentrator go directly to the NT Domain server for user authentication. We now have to add the RADIUS server as a go-between to get NT password Expiry to work. One last thing to mention is that you must use MSCHAP v2.
