Radius timeout when rlm_ldap module fail

Hi, I've used freeradius-1.1.3-1.6.el5 with openldap backend on my old system. When OpenLDAP server was down, client requested the Freeradius doesn't get any response and then requested another radius server. Now, after upgade to freeradius-2.1.9-3.el6, the behavior has changed. When backend LDAP server is down, FreeRadius responds immediately with Reject. I've read documentation and found this: Module return codes: RLM_MODULE_FAIL: Processing of this request could not be completed. Something is not working properly. FreeRADIUS responds with a reject response. It seems like it is correct behavior, but is it possible to change it as before? When backend OpenLDAP is down, freeradius should not respond to client?
