Freeradius and LDAP keepalive

[Angel L. Mateo]

Hello,

	I have a freeradius 2.1.10 running in a ubuntu (10.04) server. My users 
are in a ldap directory.

	The problem I have is that openldap server has an idle timeout (if 
there is more than this time with an idle connection, openldap closes 
the connection). So I want to know if there is some way to configure a 
keepalive on the ldap connection of freeradius.

	I have found in 
http://freeradius.1045715.n5.nabble.com/rlm-ldap-amp-TCP-KeepAlive-td2795077.html 
that it seems to be code to do this. I have checked this code with code 
from version 2.1.10 and it is there, but I think I have to configure 
something because connections are closed and I have logs like:

Sep  7 12:12:51 vulpes22 freeradius[21497]: RADIUS Requested access: 
<myuser at mydomain> (0)
Sep  7 12:12:51 vulpes22 freeradius[21497]:   [ldap-email] ldap_search() 
failed: LDAP connection lost.
Sep  7 12:12:51 vulpes22 freeradius[21497]:   [ldap-email] Attempting 
reconnect
Sep  7 12:12:51 vulpes22 freeradius[21497]: Login OK: 
[<myuser at mydomain>] (from client XXXXXXX port 10000)

	freeradius is working (it reconnects with the ldap without any 
problem), but I want to avoid this error.

	Is there any way to configure this keepalive?
