I have attempted to migrate a Windows 2003 based IAS setup to a Win2008r2 based NPS setup using MS's doc for exporting the DB from IAS and importing it into NPS on the newer server and it seems to work mostly. The VPN setup on the Cisco ASA works fine after being pointed to the new NPS install but clients on the Cisco 4400 WLC does not authenticate when that is set to use the new NPS radius setup. Obviously I missed a step or two.
I cannot find much documentation on deciphering the logs from NPS, but it seems that I am not getting to the "Secured password" sequence that I see in teh IAS log.
Has anyone done this and could give some advice? Or even a little help with what the logs are telling me about what happened when I switched the WLC over to the new radius setup? Thanks.
