Squid+Dansguardian with Active Directory (NTLM) Single Sign On WORKING!!!
-
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. -

Will have a look tomorrow again.Agreed only thing I changed after install of samba4 was copied smb.conf to smb4.conf
Ldap info there but not authenticating.. -
pfSense 2.2 broke my squid ntlm authentication too.
installing samba4, heimdal didn't solve the "No such file or directory" problem for me.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 :(
-
Check cache.log may be related to winbind_privileged file permissions.

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:
Jan 29 12:19:47 pfSense22 dansguardian[60493]: NTLM - Invalid message of length 42, message was: NTLMSSP
Jan 29 12:19:47 pfSense22 dansguardian[60493]: Auth plugin returned error code: -3
(I got an authentication-windows when I want to surf with the proxy, authentication not working and this errors in the log)And in /var/squid/logs/cache.log:

2015/01/29 12:36:19 kid1| WARNING: ntlmauthenticator #Hlpr0 exitedI have exactly the same behaviour, except that the error is not the same. mine says the following in cache.log:
2015/01/29 11:13:29 kid1| WARNING: ntlmauthenticator #Hlpr0 exited
Shared object "libpopt_samba3.so" not found, required by "ntlm_auth"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.
-
What permissions do you have under /usr/pbi/squid-amd64/bin ?
rwxr-xr-x proxy proxy
and same for ntlm_auth in this directoryAlso, 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 errorShared 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 -
Again, dont know what the error was. Tody I find the libintl.so.8 and the other needed libraries. But still not working. In /var/squid/logs/cache.log:
ntlm_auth: error opening config file /usr/local/etc/smb4.conf. Error was No such file or directory
Which file or directory? /usr/local/etc/smb4.conf is there and is readable for others.
-
May be related to pbi pseudo jail build.
Are you trying to run net ads join and getting this error?
-
no marcelloc, the net ads join is working.
I try to go into Internet with the browser over the proxy. The the Browser ask me for username and password - but he doesnt accept and I see this line in the log.Yes I think its related to the pseudeo jail buid. But i dont know anything about this till now.
-
Did anyone else get this to work? I was able to get things working by:
- Copied all the libs to the /usr/pbi/squid-amd64/local/lib directory
- Copied the smb4.conf to the /usr/pbi/etc directory
- Added –configfile=/usr/pbi/etc/smb4.conf to the ntlm_auth parameters within the Integrations section of Proxy server service under Custom Settings
Now things are rocking out with AD just fine without prompting for a password.

Well;
Have pretty given up. I even tried a new install and
pkg install http://e-sac.siteseguro.ws/packages/amd64/8/All/samba36-3.6.3.tbz does not work..
pkg install samba36 works but end result
kinit: krb5_init_context failed: 22
Is all I get..
Would be wonderfull if someone would rewrite this for a new install..
TIA
Percy -
I'm suffering with getting a 2.2 install running as well.
Sifting through a lot of the last few pages has at least got the warnings to go away but no actual ntlm auth occuring.
+1 for a modification of the original tutorial in a seperate thread perhaps? -

PercyThe samba pkg you tried to download is for freebsd 8.x.
pfsense 2.2 uses freebsd 10.

I want to implement ldap kerberos squid authentication ! As far as i understand i wont use samba but why kdc is needed if i can use windows server kdc ?
-
Anyone?

I'm using it as a lab, I've created two VM on Vbox and it can view etch other, but I can't pass this part:
6. Services –> Firewall
a. Rules –> LAN tab – Create a proxy rule to allow TCP port 3128 to the LAN address for testing (will change later)
b. NAT –> Port Forward tab - Create a proxy port forward from LAN on port 3128 to the loopback adapter (127.0.0.1) for testingcould anyone show me how to do it?
