We have migrated our ACS servers to FreeRADIUS with success. We looked into NPS and the roadblock was the realm suffix stripping. We need to strip username d...@uoguelph.ca to just 'dxu' before authenticate with active directory. NPS only strips the outer PEAP identity but not inner identity. Also NPS can strip the realm when it is running as proxy but not in local processing mode. See following discussion for more detail. We were seeing the exact same behavior:

Hello to the awesome group. We've used Cisco ACS with general satisfaction for many years as the RADIUS solution for our very, very large WLAN's 802.1X authentication. We also have Aruba Clearpass in-house for guest wireless, and have poked around at ISE a bit. We're weighing replacing our aging ACS environment, but as many of you know times are changing. When you shop for RADIUS, you have to wade through the fog of NAC systems because everything is getting ever more "feature rich". For major vendors, RADIUS is just a slice of NAC now, and since everybody "is a software company!" licensing can be ugly. I'm not slamming those who find value in the many interesting features that the likes of ISE and Clearpass offer, but I also can't help but be drawn to Microsoft NPS when I think about going forward with simple RADIUS. Way back when, we avoided Microsoft in this role as the reporting wasn't particularly strong when it came time to troubleshoot clients. We *may* have found relief to this through Splunk, and also enjoy a robust Windows server environment staffed by absolutely brilliant MS-minded veteran admins. All that being said- is anyone using NPS as their RADIUS solution for a large secure WLAN environment? Can you share likes, dislikes, regrets, endorsements, horror stories, tales of success, etc? (Any vendor reps lurking- no, I'm not open to hearing about other RADIUS solutions. Please, no calls or emails) Kind regards- Lee Badman | CWNE #200 | Network Architect Information Technology Services 206 Machinery Hall 120 Smith Drive Syracuse, New York 13244 t 315.443.3003 f 315.443.4325 e lhbad...@syr.edu<mailto:lhbad...@syr.edu> w its.syr.edu SYRACUSE UNIVERSITY syr.edu ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
