Steve, Understood on the full RADIUS 802.1X auth side, but this is for an MDU setting where clients are in BYOD, and most of those devices don't support 802.1X. So we don't know the client's MAC beforehand, and want to give each unit a single passphrase to use for all of their devices within that unit. Is it easy to make custom Access-Request variables in Hostapd? This seems to be how commercial vendors are doing this. Ruckus for example: https://docs.commscope.com/bundle/unleashed-200.10-onlinehelp/page/GUID-E0AD67EA-91EB-473D-9F14-1C7A3ADC1F1B.html and https://docs.commscope.com/bundle/unleashed-200.10-onlinehelp/page/GUID-2392DF4B-DBE7-4DD5-868E-6222118BE6D4.html On Wed, Aug 11, 2021 at 11:44 AM Steve deRosier <derosier@xxxxxxxxx> wrote: > > Hi Colton, > > > On Tue, Aug 10, 2021 at 7:02 PM Colton Conor <colton.conor@xxxxxxxxx> wrote: >> >> Michael, >> >> From the sounds of it, we don't have to convert the passphrase to the >> psk format.

Not without non-trivial changes to the code on both ends, and even then it's tricky and has various problems. > > What most people do at the point you're talking about is implement a full RADIUS 802.1X auth system. Usually requires certificates and other things managed by IT. But if you're giving personal PSKs to people, and managing that in RADIUS anyway, so you're already managing tokens for people. There's extensive documentation, online articles, and books written on the subject, so you should start there. > > - Steve > _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
