Hello everyone... Ive set up a freeradius server with LDAP backend for MSCHAP, but now I have to set up a mac based auth on the same server also with the same LDAP backend ( but the mac info is found in another subtree ). So I have made two ldap instances under modules including MSCHAP... modules { mschap { authtype = MS-CHAP use_mppe = yes require_encryption = yes require_strong = yes } ldap ldap_users { server = "81.yyy.xxx.xxx" basedn = "ou=People,dc=xxx,dc=xxx" filter = "(&(objectClass=posixAccount)(uid=%u))" start_tls = no dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 10 timeout = 4 timelimit = 3 net_timeout = 1 } ldap ldap_mac { server = "81.xxx.xxx.xxx" basedn = "ou=Hosts,dc=xxx,dc=xxx" filter = "(&(objectClass=ipHost)(ipHostNumber=%u))" start_tls = no dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 10 timeout = 4 timelimit = 3 net_timeout = 1 } ... } // modules end instantiate { weekly_traffic // just a counter } authorize { mschap ldap_users ldap_mac weekly_traffic }   authenticate { # MSCHAP authentication. Auth-Type MS-CHAP { mschap } Auth-Type LDAP { ldap_mac ldap_users } } So what I actually need is - when my vpn server sends Access-Request packets with MS-CHAP attributes, I would like mschap module to use the "ldap_users" part. And when an Access-Request packet with the mac address is recieved I would like to use ldap_mac ONLY ! here is a part of my log file... rad_recv: Access-Request packet from host 172.19.10.2:1024, id=22, length=193 Framed-MTU = 1480 NAS-IP-Address = 172.19.10.2 NAS-Identifier = "HP2626-Verwaltung" User-Name = "00:0a:e4:22:c5:9d" Service-Type = Administrative-User Framed-Protocol = PPP NAS-Port = 10 NAS-Port-Type = Ethernet NAS-Port-Id = "10" Called-Station-Id = "00-14-38-2e-2c-76" Calling-Station-Id = "00-0a-e4-22-c5-9d" Connect-Info = "CONNECT Ethernet 100Mbps Full duplex" CHAP-Password = 0x1525d56e4e21bbbc83d5e49fa3be8173a5 Debug: Processing the authorize section of radiusd.conf Debug: modcall: entering group authorize for request 0 Debug: modsingle[authorize]: calling mschap (rlm_mschap) for request 0 Debug: modsingle[authorize]: returned from mschap (rlm_mschap) for request 0 Debug: modcall[authorize]: module "mschap" returns noop for request 0 Debug: modsingle[authorize]: calling ldap_users (rlm_ldap) for request 0 Debug: rlm_ldap: - authorize Debug: rlm_ldap: performing user authorization for 00:0a:e4:22:c5:9d Debug: radius_xlat: '(&(objectClass=posixAccount)(uid=00:0a:e4:22:c5:9d))' Debug: radius_xlat: 'ou=People,dc=kolp,dc=at' Debug: rlm_ldap: ldap_get_conn: Checking Id: 0 Debug: rlm_ldap: ldap_get_conn: Got Id: 0 Debug: rlm_ldap: attempting LDAP reconnection Debug: rlm_ldap: (re)connect to 81.189.101.10:389, authentication 0 Debug: rlm_ldap: bind as / to 81.189.101.10:389 Debug: rlm_ldap: waiting for bind result ...
