Discarding Duplicate Request

[Rando Nakarmi]

I been seeing quite a large number of message like below logged in
radius.log lately.

Discarding duplicate request from client classroom98 port 32880 - ID: 131
due to unfinished request 241848

I read some thread, this might be the case when back-end server (i.e auth
servers) are too slow to respond.

My back-end is AD, using ntlm_auth.
radius version 2.1.12-4
samba version 3.5.8-68

Any hints or suggestion how to resolve this would be very helpful.

Most of the users get authenticated ( I don't think ntlm_auth is responding
slow), I could not figure this out

--cheers,
Rando
