Unfortunately it is the design of PEAP (and TTLS) to offer separate inner and outer identities. There has been a lot of discussion in the IEEE about how to better support service provider billing in these instances, but I don't know what came of those discussions. Perhaps someone else on the list knows.

How are people handling accounting records for your 802.1X wireless networks? We're in the process of rolling out EAP-PEAP, and everything is fine in terms of our RADIUS accounting records from the APs as long as the users leave the "Outer Identity" field blank - we end up with their real usernames in the accounting records. However, as soon as they fill in anything for "Outer Identity" (Mac OS X) or "Roaming Identity" (Intel Wireless utility), that text is what ends up in our accounting records. Obviously this is suboptimal in terms of relying on our accounting records for true accounting
of who was where on our network.  Is there any way around this?

FWIW, we're using Cisco 1200 APs with a WLSM/WLSE combo, Steel Belted RADIUS
talking to an Active Directory back end.

Thanks in advance!
