Greetings! I've been struggling to get PPTP authenticating through my freeradius server through to my LDAP server. I've got Fedora Directory Server as my LDAP database and I've configured freeradius according to the instructions I found for OpenLDAP (yes, this could be part of the problem but I didn't see anything specific to FDS). I've got authentication working via radtest, e.g. rad_recv: Access-Request packet from host 172.33.100.18:32811, id=116, length=56 User-Name = "joey" User-Password = "xxxxxxxx" NAS-IP-Address = 255.255.255.255 NAS-Port = 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for joey rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: (re)connect to ldap.example.net:389, authentication 0 rlm_ldap: bind as cn=Directory Manager/xxxxxxx to ldap.example.net:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: looking for check items in directory... rlm_ldap: Adding userPassword as User-Password, value { & op=21 rlm_ldap: looking for reply items in directory... rlm_ldap: user joey authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 rlm_ldap: - authenticate rlm_ldap: login attempt by "joey" with password "xxxxxxxx" rlm_ldap: user DN: uid=joey,ou=People, dc=example,dc=net rlm_ldap: (re)connect to ldap.example.net:389, authentication 1 rlm_ldap: bind as uid=joey,ou=People, dc=example,dc=net/xxxxxxxx to ldap.example.net:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: user joey authenticated succesfully Login OK: [joey/xxxxxxx] (from client el-oso port 0) Sending Access-Accept of id 116 to 172.33.100.18:32811 So that tells me that I've got the communication to my LDAP server properly configured. However when my PPTP server sends authentication requests to my radius server, I always get "Login incorrect: [joey/<no User-Password attribute>]" For example: rad_recv: Access-Request packet from host 172.33.100.1:32784, id=15, length=147 Service-Type = Framed-User Framed-Protocol = PPP User-Name = "joey" MS-CHAP-Challenge = 0x47f01bcb27f52fa649fc0722f36c30c6 MS-CHAP2-Response = 0x92001b248ce93a1a352383f8836833afeb9a0000000000000000724f55d6a62231b22c33b33265212ecd3fa334aff76bb442 Calling-Station-Id = "67.41.208.129" NAS-Identifier = "pptp" NAS-Port = 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for joey rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: looking for check items in directory... rlm_ldap: Adding userPassword as User-Password, value { & op=21 rlm_ldap: looking for reply items in directory... rlm_ldap: user joey authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 rlm_ldap: - authenticate rlm_ldap: Attribute "User-Password" is required for authentication. Login incorrect: [joey/<no User-Password attribute>] (from client vpn-external port 0 cli 67.41.208.129) Sending Access-Reject of id 15 to 71.39.18.170:32784 I have no idea where to troubleshoot this at this point. The usual suspects seem to be properly configured (ldap.attrmap, clients.conf, radiusd.conf and users). Anybody have thoughts? Thanks. --joey
