Matthew Gast has filed a series of four articles on using 802.1X with open-source projects to create PEAP authenticated networks: Matthew is one of the best writers on the subject of enterprise authentication, and author of 802.11 Wireless Networks: The Definitive Guide. His four articles at O'Reilly Network walk through his efforts to make the open-source xsupplicant 802.1X client create a successful PEAP (Protected EAP) tunnel and authentication with dynamic WEP keys. His efforts helped patch an incompatibility between xsupplicant and Microsoft's IAS server, making xsupplicant a more widely usable product. [link via Douglas Burns]
