EAP session for state problem

12 Jul 2012

      Hi,

We are using freeradius2-2.1.12-3.el5 on RHEL 5.8 for eduroaming. Sometimes
we are getting "EAP session for state ... did not finish!" warning as you
can see on case 1. We can successfully login after every three or four
tries without error (case 2).

How can I overcome this problem?

PS: I think it is more problem on windows 7.

Case 1:

rad_recv: Access-Request packet from host 10.200.0.2 port 32832, id=203,
length=238

                User-Name = "xxx@sabanciuniv.edu.tr"

                NAS-IP-Address = 10.200.0.2

                NAS-Port = 0

                NAS-Identifier = "10.200.0.2"

                NAS-Port-Type = Wireless-802.11

                Calling-Station-Id = "1C659DA0C84D"

                Called-Station-Id = "000B8661DFC4"

                Service-Type = Login-User

                Framed-MTU = 1100

                EAP-Message =
