NEW Package: freeRADIUS 2.x
-
Updates pkg v1.4.6:
- Fixed: When Plain MAC Auth is enabled we are now able to not only check against EAP-X but against all other modules. The MAC check is now before all other checks and if it fails it proceeds with the rest.
-
Updates pkg v1.4.7:
-
Added: extended features for MySQL, PostgreSQL, LDAP, Kerberos support
-
Changed: Path to new packages and its dependencies
-
Updated: FreeRADIUS 2.x package documentation on doc.pfsense.org
And the oscar goes to:
marcelloc
Thank you for compiling freeradius2 with the extended features and hosting the packages! -

I'm trying to get LDAP working but I'm getting the following output:
[ldap] ldap_search() failed: Operations error [ldap] search failed [ldap] ldap_release_conn: Release Id: 0 ++[ldap] returns fail Invalid user: [USER/PASSW]Does anyone know why this is happening? When I manually do an ldap search with another program with the same user I do get a result back.

Hello!
So Nachtfalke and marcelloc, thank you for great job!I've done the same job about two weeks ago and I regret now not sharing my work :/
I've compiled ldap, kerberos modules (don't needed mysql and other db's).So now to make AD integration possible it is necessary to have Samba and Kerberos packages.
why?
simple version, maybe little mixed up. samba has winbind, which allow kerberos to authenticate in windows domain.
winbind has module ntlm_auth which can ask server about the user, but we have to be member of domain.so what am I doing is tryin' to compile Samba 3 for Pfsense, next Kerberos and will post here about results

I'm trying to get LDAP working but I'm getting the following output:
[ldap] ldap_search() failed: Operations error [ldap] search failed [ldap] ldap_release_conn: Release Id: 0 ++[ldap] returns fail Invalid user: [USER/PASSW]Does anyone know why this is happening? When I manually do an ldap search with another program with the same user I do get a result back.
you didn't give anything about your config, but I'll try guess:
If you have MS AD try to filter:
(sAMAccountName=%{mschap:User-Name})
otherwise maybe:
(uid=%{mschap:User-Name})I don't know if you have your Identity configured properly, show it for us

Hi,
Sorry, its indeed MS AD (2008R2). I already tried with the sAMAccountName but didn't had the MSCHAP in it, tried it again, but still no luck:

as far as I know if you want filter sAMAccountName you have to use Microsoft style, so dc, dc ;) -
That did the trick :) BUT he still doesn't give me an accept message:

(The DN bind user is Administrator, so its not a permission issue - found some posts refering to this)
Also "set_auth_type = yes/no" as mentioned on Google doesn't help.

Thank you very much for your feedback. I read about the samba and winbind "problematic" to use an Active Directory with freeradius. But I am not sure at all now - I thought that Win Server 2003 and higher has LDAP compatibility but you first have to enable something on Windows Server. But I am not sure on that and I do not find the documentation…
freeradius2 has an "rlm_smb" module but this is still experimental. This is the excerpt of the makefile:
# No SMB option yet; rlm_smb is still unbuildable .ifdef(WITH_SMB) LIB_DEPENDS= smbclient.0:${PORTSDIR}/net/samba-libsmbclient CONFIGURE_ARGS+=--with-rlm_smb CONFIGURE_ARGS+=--with-rlm-smb-lib-dir=${LOCALBASE}/lib CONFIGURE_ARGS+=--with-rlm-smb-include-dir=${LOCALBASE}/include PLIST_SUB+= SMB="" .else CONFIGURE_ARGS+=--without-rlm_smb PLIST_SUB+= SMB="@comment " .endif # SMB module is still experimental .if defined(WITH_SMB) && !defined(WITH_EXPERIMENTAL) WITH_EXPERIMENTAL= yes .endifThe third thing I read about here in the forum is/was that someone had installed samba on pfsense but it breaks the hole system.
@pszafer:
You wrote you worked on freeradius2 (compiling) in the past. Did you use it on pfsense and how did you get it work with LDAP and/or AD ?
If there are samba binaries which don't breake the system I am sure we can add these to freeradius2 package and the create a GUI to edit the smb.conf. That shouldn't be to hard if we know the command lines. -
@sandern
in /usr/local/etc/raddb/sites-enabled/default
you have authentication sectionso far we've got plaint text password and this is our problem, we need nt-domain hash.
you could try comment line with unix auth
and uncomment Auth-Type LDAP, but this will propably cause other errors.
I've done this before so linux users with pap auth were authenticated succesfully, but trully I remove this and backuped in wrong place (it's gone) so I can't easy come back to this, but I don't want to.@Nachtfalke
AD is compatible with LDAP in way we wanted to.
We need Kerberos to get ticket to get authenticated - http://www.google.pl/imgres?q=kerberos+eap&um=1&hl=pl&authuser=0&biw=1920&bih=913&tbm=isch&tbnid=4SMvBpPK_Big9M:&imgrefurl=http://anil-identity.blogspot.com/2009_02_01_archive.html&docid=xeW3QfB9c27wtM&imgurl=http://identitymeme.org/wp-content/uploads/2009/02/krbandweb-opps_06-700x366.png&w=700&h=366&ei=gUcLT5qpEcmq-AaFwL20AQ&zoom=1&iact=hc&vpx=1506&vpy=159&dur=1520&hovh=162&hovw=311&tx=119&ty=97&sig=107427534317749718724&page=1&tbnh=86&tbnw=164&start=0&ndsp=53&ved=1t:429,r:8,s:0To get Kerberos working with AD we need get winbind (which is in Samba packet). Winbind is service allows to get authenticated over Windows PDC.
rlm_smb is something worth to try and interesting.About Samba compiling, I think someone could try to use samba as file sharing server so firewall would be messed up.
I wanted to use Samba only for purpose to authenticate user and I think it is possible ;)Two weeks ago I've bought new netgear router to my workplace, upgraded to OpenWRT and wanted to authenticate wifi via 802.1x.
As Domain Controller shouldn't be used for this for security reasons I decided to do it on pfsense router. Didn't search forum what's going on with this packet, didn't see this in GUI so recompiled freeradius on freebsd virtual machine and added necessary libraries for that.
I've come here because I was exhausted for tryin' ntlm_auth to work. Squid package has some ntlm_auth without samba, so I assumed it is possible. Now I think my assumption was wrong :POkay, now I'm reading about rlm_smb, maybe do something with that.
–------------------
one weird thing, in dd-wrt it is for 5 years and it is still experimental? am I missing something? -
I wanted to use Samba only for purpose to authenticate user and I think it is possible
Only if you do it by hand, installing freebsd packages.Samba as a pfSense package is really not a good idea for firewall.
-
in freebsd packages there are no security=ads. Unfortunately we need only this from samba :/
-
Ddid you tried with kerberos? there is a way to do this without samba.

@marcelloc
I will try tomorrow morning do this (in 7 hours) [other time zone ;)] -
Updates pkg v1.4.8:
- Added: Support for Redundant / LoadBalancing two LDAP Servers (authorize and authentication)
I will add redundant SQL server support in near futur, too.
PS: I found something about MS AD and LDAP and how to enable LDAP in MS Server 2003 and higher. This is not directly pointed to freeradius but perhaps it will help the guys who know more about this than me :D

Hello, here is the same and shorter version for 2008 AD, http://technet.microsoft.com/pl-pl/library/cc816788(WS.10).aspx,
but I'm not sure if this is what we want to do.
Make connection safer in one place, but less safe in other place. -

Make connection safer in one place, but less safe in other place.I don't think this is the case here. We are authenticating to ldap so its not anonymous as in the technet article. I'll try some more this afternoon to get this working.

just tell me, is command kinit working for you?
I have problem with a lot of libraries.
Now I'm stuck at error:
/usr/local/lib/libgssrpc.so: Undefined symbol "gss_mech_krb5"–---------------------------
@marcelloc
look at this configure error of compiling Kerberos from hand :Pconfigure: error: krb5 libs don't have all features required for Active Directory support
-
Hi,
I got this on i386 and amd64 - does this help you?
[2.0.1-RELEASE][admin@pfsense.localdomain]/root(1): kinit /libexec/ld-elf.so.1: /usr/local/lib/libkrb5.so: Undefined symbol "add_error_table" -
No, i'll Google for it. ???
