Hi,

does anybody have "dot1x port-based authentication" up and running for
WinXP/Cisco Catalyst/Freeradius ? (see
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/1216ea2/scg/swg8
021x.htm#10608). I have a LAN-connection in WinXP configured with 802.1x
enabled using EAP-MD5. Set up the radius-settings on a Catalyst 6009 and
enabled dot1x ("port-control auto"). The Freeradius (latest
nightly-snapshot) is running with the new EAP-MD5 module (thanks a lot for
this work). After startup WinXP prompts for Username/Password to
authenticate for the LAN-connection. The Freeradius debug-ouput is the
following:

Freeradius sends about 40 EAP-Messages until it fails with a core dump.

Thanks a lot for your help.
