          Or should enter the MYADMIN@MYDOMAIN.LOCAL account?

          Login with MYADMIN@MYDOMAIN.LOCAL not accept the password.

          to enter with pfSense Firewall Local ADMIN if income perfectly. Running / usr / local / bin / kinit myadmin net ads join-U myadmin
          Result:

          myadmin@MYDOMAIN.LOCAL.'s Password:

          When entering the password, it gives the following error:
          kinit: krb5_get_init_creds: unable to reach any KDC in realm mydomain.local.

          NOTE: I have a DC with mydomain.local domain and create a user myadmin

          Who can help me validate that I like to check and validate against the server.

          Tengo un problema, en el paso 13.

          Ingresar vía SSH usando PuTTY, ingreso como ADMIN local del Firewall PFSENSE ?
          O deberia ingresar con la cuenta  MYADMIN@MYDOMAIN.LOCAL ?

          Login con MYADMIN@MYDOMAIN.LOCAL no acepta la contraseña.

          al ingresar con ADMIN local del Firewall PFSENSE si ingreso, perfectamente. Al ejecutar /usr/local/bin/kinit myadmin net ads join -U myadmin
          Resultado:

          myadmin@MYDOMAIN.LOCAL.'s Password:

          Al ingresar la Contraseña, da el siguiente error:
          kinit: krb5_get_init_creds: unable to reach any KDC in realm MYDOMAIN.LOCAL.

          NOTA: Tengo un DC con el dominio MYDOMAIN.LOCAL y cree un usuario myadmin

          Quien me puede ayudar a validar que debo verificar y como para que se valide contra el servidor.

            I had similar issues and I simply replaced the hostnames with their IPs.

                you will need a samba3 or 4 compiled on freebsd to use it.

                  Ok so tried updating to 2.2
                  my squid custom integretion

                  http_access allow whitelist
                  acl_uses_indirect_client on
                  follow_x_forwarded_for allow localhost
                  auth_param ntlm program /usr/local/bin/ntlm_auth –use-cached-creds --helper-protocol=squid-2.5-ntlmssp
                  auth_param ntlm children 10
                  auth_param ntlm keep_alive on
                  acl password proxy_auth REQUIRED
                  http_access allow password

                  Squid will now not start because of
                  auth_param ntlm program /usr/local/bin/ntlm_auth --use-cached-creds --helper-protocol=squid-2.5-ntlmssp

                  Shared object "libcrypto.so.6" not found, required by "ntlm_auth" which was part of squid 2.5 isntall i believe..

                  Any ideas.. I take that line out and authentication fails

                    Ok so found out that samba36;samba-devel;heimdal were uninstalled..
                    So reinstalled samba36;samba4(this isn't samba-devel;heimdal..
                    Had to copy smb.conf to smb4.conf
                    but get an error when starting squid..
                    ERROR: auth_param ntlm program /usr/local/bin/ntlm_auth: (2) No such file or directory FATAL: auth_param ntlm program /usr/local/bin/ntlm_auth: (2) No such file or directory
                    But the directory exists..
                    I would think passing windows username would be this difficult.. Looked at the Squidtrust article.. but didnt look as simple as let on..
                    Not too concerned with someone spoofing the username..
                    Just need to pass it to squid…
                    Thx

                      Thanks for this thread! Now my sso is running on pfsense 2.1.
                      But now 2.2 is out and I also would like to upgrade to 2.2. Anyone can help?
                      I have the sam problems like percyiii. Already described in my german thread https://forum.pfsense.org/index.php?topic=86972.msg477384#msg477384 and described in the squid-forum:
                      http://squid-web-proxy-cache.1019090.n4.nabble.com/ntlm-No-such-file-or-directory-td4669085.html

                      Would be very nice to get help, if I can do anything to help, I would do it.

                      Greetings Alex

                        On 2.2, try install packages from freebsd repo using  pkg install instead of pkg_add from my repo.

                        Samba 3 does not have ad options compiled but samba4 may have.

                          Ok, it looks not so bad.
                          Have done the complete procedure on pfsense 2.2 but with "pkg install samba4" and "pkg install heimdal".
                          Somewhere I had to use samba4 insted of samba.
                          The squid Problem with " /usr/local/bin/ntlm_auth: (2) No such file or directory" is gone. squid is running.
                          The Ldap-Informations about groupmembers are working. Also wbinfo -u and wbinfo -g working correct.

                          But I don't see the domain username in the dansguardian-log. So I think sso is not functional in the moment. But one step further today.
                          Will have a look tomorrow again.

                            pfSense 2.2 broke my squid ntlm authentication too.
                            installing samba4, heimdal didn't solve the "No such file or directory" problem for me.

                              Agreed only thing I changed after install of samba4 was copied smb.conf to smb4.conf
                              Ldap info there but not authenticating..

                                You'll have to "copy" the ntlm_auth into the directory /usr/pbi/squid-amd64/bin/ and change that in the configuration accordingly. That solved the "No such file or directory" issue for me.

                                Now, machine is in AD, can see users and groups and what not, but the authentication prompts me for password and doesn't seem to work at all :(

                                    Yesterday I thought the "No such file" error is solved. But today squid was not starting because of this error. Now I tried the solution from ghosterius, and the error is gone, squid is running.
                                    In the systemlog I see:

                                      I have exactly the same behaviour, except that the error is not the same. mine says the following in cache.log:

                                      What permissions do you have under /usr/pbi/squid-amd64/bin ? Also, are you using pfSense on x64 or x86? Because if it is on 32bit you should adapt that directory accordingly.

                                        and same for ntlm_auth in this directory

                                        Also, are you using pfSense on x64 or x86?

                                        x64

                                          ok, I had a silly error in my "Squid Integrations"!!!
                                          So my error is exactly the same as written by ghosterius
                                          WARNING: ntlmauthenticator #Hlpr0 exited
                                          Shared object "libpopt_samba3.so" not found, required by "ntlm_auth"

                                            Ok, this problem is because libpopt_samba3.so and many other libs can not be found because they are in the path /usr/local/lib/samba
                                            so you should add this path to the ldconfig-path or copy/link the libraries where they could be find. But now I have the error

                                            Shared object "libintl.so.8" not found, required by "libpopt.so.0"

                                            And I cannot find libintl.so on my pfsense. So what I have to install to get this shared object?

                                            Thanks in advance
                                            Alex
