we invested in EAP-TLS this year - so the PEAP crush is less of an issue 
(over 60% of clients are now EAP-TLS but clients configured over past years
are still PEAP until they have issues and the users get their devices reconfigured).

however, this performance improvement is still of interest - and there are
some subtle tweaks that can be done to improve the ntlm_auth (and Cisco wireless
controller) behaviour

Its likely to go into 3.0.x - its 2.2.x thats not likely to be touched
