Hi, I'm using Freeradius 1.1.6 inside a Solaris 10 zone and compiled it from vanilla sources. I configured rlm_ldap since the usernames and cleartext-passwords are stored in an LDAP directory and it works just fine for applications like Cisco-VPN or 802.1X EAP-TTLS. Now I wanted to set up the Captive Portal of pfsense/m0n0wall to authenticate against radius, which is using PAP for password transmission but authentication always fails even if I triple-check the entered user credentials. The freeradius log always says: Auth: Login incorrect (rlm_ldap: Bind as user failed): [my_username] (from client pfsensebox port 1 cli 00:17:f2:xx:yy:zz) Of course I also checked if the radius client is using the correct secret. I set auto_headers to "yes" as it is suggested in the rlm_pap manpage and put pap at the end of the authorize section. I also included an excerpt of my radiusd.conf ---begin radiusd.conf--- modules { pap { auto_header = yes } ldap { server = "ldapserver.mydomain.com" basedn = "ou=people,o=my organization,c=de" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})" start_tls = no access_attr = "uid" dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 password_attribute = userPassword timeout = 4 timelimit = 3 net_timeout = 1 } } authorize { auth_log chap mschap suffix eap ldap files daily pap } authenticate { pap chap mschap ldap eap } ---end radiusd.conf--- Here is an output of radiusd -X: ---begin radiusd -X output--- rad_recv: Access-Request packet from host 111.222.333.444:51087, id=255, length=131 NAS-IP-Address = 111.222.333.444 NAS-Identifier = "pfsense.local" User-Name = "my_username" User-Password = "\301q\202\355g\264g)N\265\315\311\374\205i" Service-Type = Login-User NAS-Port-Type = Ethernet NAS-Port = 1 Framed-IP-Address = 192.168.23.200 Called-Station-Id = "00:01:02:xx:yy:zz" Calling-Station-Id = "00:17:f2:aa:bb:cc" Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 radius_xlat: '/opt/radiusd/var/log//radacct/auth-detail-200709' rlm_detail: /opt/radiusd/var/log//radacct/auth-detail-%Y%m expands to /opt/radiusd/var/log//radacct/auth-detail-200709 modcall[authorize]: module "auth_log" returns ok for request 0 modcall[authorize]: module "chap" returns noop for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "my_username", looking up realm NULL rlm_realm: Found realm "NULL" rlm_realm: Adding Stripped-User-Name = "my_username" rlm_realm: Proxying request from user my_username to realm NULL rlm_realm: Adding Realm = "NULL" rlm_realm: Authentication realm is LOCAL. modcall[authorize]: module "suffix" returns noop for request 0 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for my_username radius_xlat: '(uid=my_username)' radius_xlat: 'ou=people,o=my organization,c=de' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: (re)connect to directory.fernuni-hagen.de:389, authentication 0 rlm_ldap: bind as / to directory.fernuni-hagen.de:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: performing search in ou=people,o=my organization,c=de, with filter (uid=my_username) rlm_ldap: checking if remote access for my_username is allowed by uid rlm_ldap: looking for check items in directory... rlm_ldap: Adding uid as User-Name, value my_username & op=21 rlm_ldap: looking for reply items in directory... rlm_ldap: Setting Auth-Type = ldap rlm_ldap: user my_username authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 0 modcall[authorize]: module "files" returns notfound for request 0 rlm_counter: Entering module authorize code rlm_counter: Could not find Check item value pair modcall[authorize]: module "daily" returns noop for request 0 rlm_pap: WARNING!

Double-check the shared secret on the server and the NAS! ---end radiusd -X output--- What seems very curious to me is that my password, though delivered in cleartext, seems broken since the password in the following line is actually not the real password: rlm_ldap: login attempt by "my_username" with password "Áq?íg ´g)NµÍÉü?i" Is it the client that does those nasty things or is my freeradius just misconfigured? How can I get it to work? Thanks in advance, Thomas
