Hello, I'm trying to make working LDAP as authentication backend for RADIUS. I verified that the data are right and the query to LDAP is properly working if I use ldapsearch. I experience this "rad_recv: Access-Reject packet from host 127.0.0.1:1812, id=78, length=20" when I try from radtest ... This is the output of radiusd in debug-mode: rad_recv: Access-Request packet from host 127.0.0.1:59221, id=78, length=60 User-Name = "ldapuser" User-Password = "121212" NAS-IP-Address = 255.255.255.255 NAS-Port = 2 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 2 modcall[authorize]: module "preprocess" returns ok for request 2 modcall[authorize]: module "chap" returns noop for request 2 rlm_ldap: - authorize rlm_ldap: performing user authorization for ldapuser radius_xlat: '(uid=ldapuser)' radius_xlat: 'dc=example,dc=com' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in dc=example,dc=com, with filter (uid=ldapuser) rlm_ldap: Added password 121212 in check items rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: Setting Auth-Type = ldap rlm_ldap: user ldapuser authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 2 modcall: leaving group authorize (returns ok) for request 2 rad_check_password: Found Auth-Type ldap auth: type "LDAP" Processing the authenticate section of radiusd.conf modcall: entering group LDAP for request 2 rlm_ldap: - authenticate rlm_ldap: login attempt by "ldapuser" with password "121212" rlm_ldap: user DN: uid=ldapuser,ou=People,dc=example,dc=com rlm_ldap: (re)connect to localhost:389, authentication 1 rlm_ldap: bind as uid=ldapuser,ou=People,dc=example,dc=com/121212 to localhost:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind failed with invalid credentials modcall[authenticate]: module "ldap" returns reject for request 2 modcall: leaving group LDAP (returns reject) for request 2 auth: Failed to validate the user.

You're using LDAP with POSIX type users, including shadow passwords. I'm pretty sure this means you cannot use CHAP on the client end, but must use PAP. Somebody can correct me if I'm wrong about this. While they are at it, maybe they can let me know how to get FreeRADIUS to respect the shadow password aging attibutes. :-/

You're using LDAP with POSIX type users, including shadow passwords. I'm pretty sure this means you cannot use CHAP on the client end, but must use PAP. Somebody can correct me if I'm wrong about this.
While they are at it, maybe they can let me know how to get FreeRADIUS to respect the shadow password aging attibutes. :-/

rlm_ldap: Setting Auth-Type = ldap
Hmmm ... that's odd. I thought rlm_ldap was supposed to just grab attributes (e.g. Cleartext-Password) and not set the Auth-Type? Are you doing anything special like forcing Auth-Type := LDAP?
I was following a tutorial, this one:
http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch31_:_Centr...
rlm_ldap: user ldapuser authorized to use remote access
this line says there's a user called ldapuser
rlm_ldap: - authenticate rlm_ldap: login attempt by "ldapuser" with password "121212" rlm_ldap: user DN: uid=ldapuser,ou=People,dc=example,dc=com rlm_ldap: (re)connect to localhost:389, authentication 1 rlm_ldap: bind as uid=ldapuser,ou=People,dc=example,dc=com/121212 to localhost:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind failed with invalid credentials
... while this one says the bind failed. Is the password correct?
I configured that password..., it could be some problem of hasing..., maybe.

Syntax of 2.x is really is quite different from 1.y _ That was my problem, thanks an regards. Max Il 20/07/11 18.07, up@3.am ha scritto:
You're using LDAP with POSIX type users, including shadow passwords. I'm pretty sure this means you cannot use CHAP on the client end, but must use PAP. Somebody can correct me if I'm wrong about this.
While they are at it, maybe they can let me know how to get FreeRADIUS to respect the shadow password aging attibutes. :-/

Hello, I'm trying to make working LDAP as authentication backend for RADIUS. I verified that the data are right and the query to LDAP is properly working if I use ldapsearch.
does LDAP BIND work correctly using ldapsearch (i.e. ldapsearch -D)

rlm_ldap: Setting Auth-Type = ldap
Hmmm ... that's odd. I thought rlm_ldap was supposed to just grab attributes (e.g. Cleartext-Password) and not set the Auth-Type? Are you doing anything special like forcing Auth-Type := LDAP?
I was following a tutorial, this one:
http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch31_:_Centr...
rlm_ldap: user ldapuser authorized to use remote access
this line says there's a user called ldapuser
rlm_ldap: - authenticate rlm_ldap: login attempt by "ldapuser" with password "121212" rlm_ldap: user DN: uid=ldapuser,ou=People,dc=example,dc=com rlm_ldap: (re)connect to localhost:389, authentication 1 rlm_ldap: bind as uid=ldapuser,ou=People,dc=example,dc=com/121212 to localhost:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind failed with invalid credentials
... while this one says the bind failed. Is the password correct?
I configured that password..., it could be some problem of hasing..., maybe.

NOW, when I try the auth: radtest ldapuser 121212 localhost 2 testing123
I get this output on the client side
Sending Access-Request of id 207 to 127.0.0.1 port 1812 User-Name = "ldapuser" User-Password = "MTIxMjEyIA==" NAS-IP-Address = 127.0.0.1 NAS-Port = 2 rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=207, length=20
AND this one on the radius server side:

Do you have any idea? I'm not seeing something?
