Hi, Maybe your problem be in your slapd.conf permissions (access to...). I had same problem, my ldap module loaded fine on freeradius server(debian lenny), but I got "accept-reject ..." error when I ran radtest command. I deleted my "access to ..." block for freeradius server directory in slapd.conf file on my remote openldap server, so I solved my problem.

I successfully configured freeradius (version 1.x Ubuntu) to use ldap on a localhost via WPA. I am trying to setup version 2.1 (Ubuntu) to use a remote ldap server now. The module loads fine and I made what I believed were the correct changes to connect to the remote server, but I have missed something.

So... what is going wrong?

...

Is there a good doc for ldap authentication on a remote host?

Type "ldap" into the search bar on wiki.freeradius.org.

See doc/rlm_ldap, which comes with the server.

Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Whoops... /modules/ldap is on the local freeradius server, not the the remote ldap server.

/modules/ldap: (on remote ldap server)

ldap {

server = "10.10.3.1" basedn = "dc=lctn,dc=org" filter = "(uid=%{Stripped-User-Name:-%{User-Name}})"

/etc/ldap/slapd.conf (on remote ldap server)

Commented out access statements.

#access to attrs=userPassword # by dn="cn=admin,dc=lctn,dc=org" write # by anonymous auth # by self write # by * none

/freeradius/radiusd.conf (added ldap module)

instantiate {

exec

expr ldap

...

So... what is going wrong?

The FAQ says to use radiusd -X> debug.txt for debug. I get the following: The program 'radiusd' can be found in the following packages: * radiusd-livingston * xtradius * yardradius Is there another way to launch debug mode in version 2.1?

Yes, but when I try to use -X , it says: Usage: /etc/init.d/freeradius start|stop|restart|force-reload On 6/24/2010 10:18 AM, Alan DeKok wrote:

Your OS vendor likely installed it as "freeradius".

That brings me back to my first post-no radiusd. On 6/24/2010 10:26 AM, Phil Mayers wrote:

That's the init script. Run the daemon directly:

/usr/sbin/radiusd -X - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

Well, maybe it's in a different location. What OS are you using? Have you queried the package manager for your OS to find the location of the binaries? If you didn't use a package manager, and installed from source, what locations did you ./configure with? /usr/local/sbin/radiusd is most likely. Have you tried "locate radiusd". Or "find / -name radiusd"? Or, run it from the init script, then do: pgrep radiusd ls -l /proc/$PID/exec These are all pretty basic Unix/Linux skills.

Thanks for the info. I'm not sure how to determine what to use in ldap.attrmap, but will see what I can figure out. One question though; before attempting this current setup, I installed freeradius_1.1.0-1ubuntu2.1_i386.deb and ldap on the same localhost.. radtest and authenticating via WPA worked perfectly using the same user credentials I am using today from my new radius server. The difference is the version and the fact the radius server is on a different box. What might need to be configured differently now that freeradius is on a seperate box?

You don't have the userPassword mapped in /etc/raddb/ldap.attrmap

But even if you did, ldap has this:

userPassword:: e1NIQX13ak83dXhlS3FYR0NFVlhPTEVzVUo4OW9DWFE9

and the request has this:

User-Password = "password"

They aren't the same are they? The LDAP entry looks like a hash, you'll have to figure out which kind. Note it does not contain a {hash} prefix so FreeRADIUS can't figure what kind of hash it is. You'll have to force that with the right radius attribute for userPassword in ldap.attrmap.

But you better look at this:

http://deployingradius.com/documents/protocols/compatibility.html

and understand the consequences.

No. This is a new install. Nothing has been copied over. Thanks for the pointers. I will keep working at it.

I hope you didn't just copy 1.x configuration over to 2.x, they aren't compatible.

I see from your debug output you're running 2.1.0 but the current version is 2.1.9. To the best of my knowledge 2.1.9 is available as pre-built binaries for all the major distributions.

The behavior you're seeing has nothing to do with whether the ldap server is on the same host as the radius server.

I have been reading and looking at similar post non-stop and have an idea what is wrong, but am not sure how to fix it. I understand there may be a need to map ldap and radius attributes and I have found a couple examples, but I am not entirely sure what the changes should be. It seems the other problem may be the authentication being used., maybe a combination of both. I would guess I'm about one or two config changes from getting this to work. The ldap user I am trying to authenticate was created via: ./migrate_group.pl and # ldapadd on the ldap server Not sure if that helps identify the changes I need to make???

No, the two colons in ldapsearch output just indicate that the attribute value is MIME-encoded. It can be decoded for example with:

% echo e1NIQX13ak83dXhlS3FYR0NFVlhPTEVzVUo4OW9DWFE9 | mimencode -u {SHA}wjO7uxeKqXGCEVXOLEsUJ89oCXQ= % echo e1NIQX13ak83dXhlS3FYR0NFVlhPTEVzVUo4OW9DWFE9 | perl -e 'use MIME::Base64; print decode_base64(<>);' {SHA}wjO7uxeKqXGCEVXOLEsUJ89oCXQ=

It happens that way when you're new sometimes :) The last couple posts helped. I am now able to get an "Accept" message when connecting with the rootdn user. Working on getting other users to authenticate now. Thanks for your patience and help. Raymond On 6/24/2010 3:57 PM, Alan DeKok wrote:

Sorry... but the symptoms here are clear. Many, many, posts, full of confused "what do I do now" questions.

It's not that hard. Stop fighting it, and simplify it instead.

Configure a user in LDAP.

Ensure that the LDAP database has their *plain text* password.

Check that "ldapsearch" returns the *plain text* password.

Install FreeRADIUS, using the *default configuration*.

Configure FreeRADIUS to point to the LDAP server.

Try PAP authentication.

It *will* work.

Got things working (yeah!)

Had to reset the users password with ldappassword. For some reason freeradius couldn't read what was exported to the ldif file. Once I changed passwords with ldappassword, radtest and WPA worked perfectly.

Also had to comment out this line in /etc/ldap/slapd.conf:

#access to attrs=userPassword

This is what happens when people mess with passwords... now who knows who else can read them. -- 2. That which causes joy or happiness.

I misunderstood the instructions. Made the change, and I see now that I am at least connecting to the ldap server, but still getting rejected.

[ldap] performing user authorization for billy ++[ldap] returns ok No authenticate method (Auth-Type) configuration found for the request:

You use PAP, and have ldap in authorize, but not in authenticate. You likely want the latter, too. authenticate { [...] Auth-Type LDAP { ldap } [...] } This will perform an authenticated bind on the LDAP server using the supplied password, which is probably what you want.

ldpasearch on remote ldap server: root@relay-1:/etc/ldap# ldapsearch -x -b uid=billy,ou=People,dc=lctn,dc=org

On that note, the above would be the equivalent of this: ldapsearch -x -b ou=People,dc=lctn,dc=org -D uid=billy,ou=People,dc=lctn,dc=org -W ...and passing in the User-Password attribute value as the password. -- 2. That which causes joy or happiness.
