freeRadius fails to authenticate the users

[Niloofar Toorchi]

Hi All,

We are using freeRadius to authenticate 16 supplicants. The early ones get authorized but the last 3 or 4 ones get rejected corresponding the following logs in freeRadius:

Found Auth-Type = EAP
# Executing group from file /etc/freeradius/sites-enabled/default
+group authenticate {
rlm_eap: No EAP session matching the State variable.
[eap] Either EAP-request timed out OR EAP-response to an unknown EAP-request
[eap] Failed in handler
++[eap] = invalid
+} # group authenticate = invalid
Failed to authenticate the user.
Login incorrect: [user] (from client 0.0.0.0/0 port 0)
Using Post-Auth-Type Reject
# Executing group from file /etc/freeradius/sites-enabled/default
+group REJECT {
rlm_eap: No EAP session matching the State variable.
[eap] Either EAP-request timed out OR EAP-response to an unknown EAP-request
[eap] Failed to get handler, probably already removed, not inserting EAP-Failure
++[eap] = noop
[attr_filter.access_reject] 	expand: %{User-Name} -> user
attr_filter: Matched entry DEFAULT at line 11
++[attr_filter.access_reject] = updated
+} # group REJECT = updated
Delaying reject of request 26 for 1 seconds

Can any one help me to tackle this problem?

Thanks,
Niloofar
