Hi, It's been a long time, as the freeRADIUS software I've being using for the last 3 years hasn't needed looking at since installation. So a big thank you to the development team J However, as with most things it's so good I've now got to redesign and re-implement to encompass more of our infrastructure, and I'm having problems. I have a number of settings in the _users_ file that are based on the _Called_Station_ID_ then proxy the requests to a specified REALM. i.e. DEFAULT Called-Station-Id == "<a telephone number>", Proxy-To-Realm := "NULL" Fall-Through = Yes DEFAULT Called-Station-Id == "<another telephone number>", Proxy-To-Realm := "NULL" Fall-Through = Yes DEFAULT Called-Station-Id == "<yet another number>", Proxy-To-Realm := "SPECIAL" Fall-Through = Yes Now, the NULL realm is defined in the proxy.conf file as: realm NULL { type = radius authhost = radiusserver.some.domain:1645 accthost = radiusserver.some.domain:1646 Secret = radiussecret } This works and actually points to a MS IAS server going against an NT4 Domain. Now I need to authenticate a different set of users (who dial a different number) against an LDAP repository, so as you can see from my _users_ file I direct them at the "SPECIAL" realm, which I have set as follows in proxy.conf: realm SPECIAL { type = radius authhost = LOCAL accthost = LOCAL } My plan was for this to then use the local radius server, which has an _ldap_ module configure, which from what I can make out is working: ldap { server = "127.0.0.1" basedn = "dc=some,dc=domain,dc=co,dc=uk" filter = "(uid=%u)" start_tls = no dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 timeout = 4 timelimit = 3 net_timeout = 1 } And then in the authorize and authenticate sections simply include _ldap_ authorize { preprocess chap eap ldap files mschap } authenticate { Auth-Type PAP { pap } Auth-Type CHAP { chap } Auth-Type { mschap } unix ldap eap } Now all I see when using NTRadping, and sending the additional _Called_Station_Id_ attribute set to the required number is the following in my _radius.log_ Error: Dropping packet from client Dave_Test:2328 - ID: 2 due to dead request 5018 When I run the radiusd with the -X flag (bearing in mind it's an Production Service) I can make out the call being made to my LDAP server and a "rlm_ldap authorize", but then the request just finishes without giving me and Access-Accept packet, and the relevant settings from the _radreply_ table in the Postgres Database?

If one of you guys has had to do something similar, or can see any glaring omissions in my config (which I seem to think there is) could you please point me in the right direction. TIA Dave Shepherd
