I set up a 2811 for a client vpn connection that authenticates against a Microsoft IAS server using Active Directory credentials. It was working fine up until recently.
The server was a 2003 Standard server on SP1. Immediately after upgrading to SP2, RADIUS authentication quit working. I verified that the versions of IAS b/w SP1 and SP2 indeed changed. NO CONFIGURATION CHANGES were made on either the router or the IAS service. When I attempt to login using RADIUS, the IAS service logs a successful attempt, but the client will timeout, as if it is no longer receiving a response from the IAS server.
Has anyone run into anything like this since SP2 came out? Everything is set up according to the Cisco ASA 7.X/IAS Server config guide.
