      You can click on "Downloads" and then download all the modules.
      But in every folder there is a "makefile" so I think you have to compile the files first and that is my problem:
      pfsense itself does not have developement tools installed (because you don't need them) and I do not have any other freeBSD 8.x environment where I could compile these files and then just copy them on pfsense.

      perhaps someone else can do this for us?!

        Hi,

        I played around with freeRADIUS and the rlm_ldap module.

        First I downloaded the freeRADIUS 1.1.8 source from here:
        ftp://ftp.freeradius.org/pub/radius/freeradius-1.1.8.tar.gz

        Then I downloaded the PC-BSD8.2 (amd64) from here:
        http://www.pcbsd.org/

        Then I installed PC-BSD8.2 on VMware Workstation and installed freeradius on the machine:

        ./configure
make
make install

        This worked for me. All additional modules were installed in

        /usr/local/lib/

        They all start with "rlm_"

        There is the rlm_ldap module, too and freeRADIUS is starting when enabling ldap in radius.conf.
        After this I thought I just need to copy this module from PC-BSD to pfsense. pfsense stores the freeRADIUS modules is /usr/local/lib/ ,too.
        But it didn't work.

        I attached you the rlm_ldap module I copiled with PC-BSD and I attached you alle the modules I compiled with PC-BSD.
        Perhaps someone can help us to find out why this module isn't working. Not sure if these modules are independent from i386 and amd64 but I tried with pfsense amd64 and PC-BSD8.2 amd64

        All freeRADIUS modules:

          Can you upload all rlm_* modules to mediafire/rapidshare/email?

                I searched for this problem and found something in the FAQ.
                It is related to mySQL but it seems that the problem is the same as for LDAP.

                http://wiki.freeradius.org/FAQ#It+says+%22Could+not+link+…+file+not+found%22%2C+what+do+I+do%3F

                Perhaps we have to modify the    $PATH    variable in pfsense.
                But I really don't know.

                  Hi,

                  I got the solution and I got it running with the rlm_ldap module on my pfsense 2.0 final amd64:

                  This are the additional files you need:
                  rlm_ldap:
                  http://www.mediafire.com/?966eei7qg46avvu
                  I uploaded this file via GUI "Diagnostics -> Command Promt" to pfsense. The rlm_ldap.tar is now locates in /tmp.
                  Then I did this:

                  
cd /tmp
tar -xf rlm_ldap.tar
cd /usr/local/lib
mv /tmp/usr/local/lib/rlm_* .

                  After doing a ldd on rlm_ldap.so I got the solution. Some libraries are missing.

                  ldd /usr/local/lib/rlm_ldap.so

                  will give you the solution.

                  I uploaded libldap.tar to my pfsense:
                  http://www.mediafire.com/?nclfti7ndz8yr6o

                  Then I did this:

                  
cd /tmp
tar -xf libldap.tar
cd /usr/local/lib
mv /tmp/libldap* .

                  After doing a ldd on rlm_ldap.so again I got the last missing libraries:
                  I uploaded liblber.tar to my pfsense:
                  http://www.mediafire.com/?08hpaghl26lky0k

                  Then I did this:

                  
cd /tmp
tar -xf liblber.tar
cd /usr/local/lib
mv /tmp/liblber* .

                  To make the changes in radius.conf permanent I edited the following file:

                  /usr/local/pkg/freeradius.inc

                  I uncommented four lines in these two sections:

                  authorize {
(.....)
        ldap
(.....)

authenticate {
(.....)
        Auth-Type LDAP {
                ldap
        }
(.....)

                  This is the LDAP output after starting freeRADIUS with radiusd -X

                  Please let me know if this works for you.
                  And if yes please add here what you need to change to make freeRADIUS work with your LDAP.
                  Perhaps we are able to implement the changes you are doing by hand in the radiusd.conf to the GUI.

                    After added liblber, "ldd /usr/local/lib/rlm_ldap.so" still gives:

                    ldd: /usr/local/lib/rlm_ldap.so: not a dynamic executable

                    And after all of this, radiusd -X gives:

                    radiusd.conf[256] Failed to link to module 'rlm_exec': file not found

                    ls /usr/local/lib/rlm_exec*
/usr/local/lib/rlm_exec-1.1.8.la /usr/local/lib/rlm_exec.a        /usr/local/lib/rlm_exec.so
/usr/local/lib/rlm_exec-1.1.8.so /usr/local/lib/rlm_exec.la

                    Strangely.

                      Hi,

                      please go to /usr/local/lib and delete all "rlm_*" files.
                      Then deinstall freeradius package from the GUI and the reinstall the freeradius package from the GUI.

                      Then use then just add the three files from my last post:
                      rlm_ldap.tar
                      libldap.tar
                      liblber.tar

                      And pay attention. I used the "move" command "mv" NOT the "copy" "cp".

                      If you use the "ls -la" command in /user/local/lub than you can see that there are several links on the files. Cannot explain that exact.
                      The extracted files you downloaded from my .tar files have these links. But if you copy them they lose these link. That's the reason why I used "mv" instead of "cp".

                      Please try that again and post back.
                      If it does not work I will do a complete clean install of pfsense this afternoon/evening and try again.
                      I just think that you or I mixed up some libraries and so it is working for me but not for you. But we know that it will work with this minor fixes ;o)

                      –--- edit -----

                      I did a complete and fresh reinstallation of pfsense and then did the steps I described above and freeRADIUS is starting.

                      ----- edit 2 -----

                      I did a test with like it is described in the tutorial you posted and I got this output:

                      radtest username "password" localhost 1 testing123

                      [2.0-RELEASE][admin@pfSense.localdomain]/root(2): radtest username "password" localhost 1 testing123
Sending Access-Request of id 1 to 127.0.0.1 port 1812
        User-Name = "username"
        User-Password = "password"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 1
^C
[2.0-RELEASE][admin@pfSense.localdomain]/root(3):

                      /usr/local/sbin/radiusd  -X -A

                      rad_recv: Access-Request packet from host 127.0.0.1:57602, id=1, length=60
        User-Name = "username"
        User-Password = "password"
        NAS-IP-Address = 255.255.255.255
        NAS-Port = 1

                      Logging to syslog gave me this output - of course I do not have any ldap server:

                      Dec 1 16:53:21 	radiusd[31420]: rlm_ldap: (re)connection attempt failed

                        Is LDAP working for you now ?

                        It would be greate to know if it is working now with the compiled module. I do not have any LDAP here to test with.

                        Thanks for your feedback!
