Well, apparently http://e-sac.siteseguro.ws/ is down. Where else can I find the packages?

A similar thing happens to me:

wbinfo -t shows "checking the trust secret for domain blablabla via RPC calls succeeded"

but

wbinfo -u doesn't show anything

also

wbinfo -a username let's me authenticate

any ideas?

Ok, a few things, since no one has replied so far:

I'm on 2.1.4 x86

One of the packages (not sure which) broke the package manager, and now i get an error "Fatal error: Call to undefined function curl_init() in /etc/inc/pfsense-utils.inc on line 1641 " when pfsense checks for updates. Also, I can't install any new packages.
Not sure who mantains http://e-sac.siteseguro.ws/packages but the ldd folder is gone, for both x86 and x64, so I'm not sure where to find those files if I want to make a fresh install.
wbinfo -u problem is still happening

fedetehue

Well, after doing some stuff. I joined pfsense to my domain. wbinfo works (groups and users show).

But now Dansguardian doesn't show any users in the Users tab.

php /usr/local/www/dansguardian_ldap.php shows "User list from LDAP is already the same as current group, no changes made"

Any ideas?

fedetehue I have the same problem, I also have two more problems: https://forum.pfsense.org/index.php?topic=82765.0

Does anyone have any idea? I don't know how to solve that :-\

Thanks for the input.

I have a problem in step 13.

Login via SSH using PuTTY, home income ADMIN pfSense Firewall?
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.

Gracias por el aporte.

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.

PfSense 2.2 + squid3 + squidguard-devel integration with Active Directory
works this configuration?
can anyone help me?

marcelloc

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

percyiii

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

percyiii

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 :(
