Re: FreeRadius/LDAP conf : little problem
Selon Paul Bender [EMAIL PROTECTED]: Yes, the passwords are stored. Only the NT-Password is used for the PEAP/EAP-MSCHAP-V2 authentication. If you use the LDAP schema provided with Samba version 3, then the LM-Password is sambaLMPassword and the NT-Password is sambaNTPassword. If you use this schema, then you will need the adjust the mapping in FreeRADIUS's ldap.attrmap file, because the file is configured to map the attributes from the Samba version 2 LDAP schema. Hi, I got a Samba v2 schema, everything working fine with that, but i don't have any 0x in front of the hashed ntPassword. In the radiusd.conf it's said it won't work without the 0x ... but when i try to manually add it to the password so i have a real length of 32, of course i can't log in anymore ... would you have any idea of where the problem reside ?

Re: FreeRadius/LDAP conf : little problem
Selon Paul Bender [EMAIL PROTECTED]: When you say that you manually add the hashed NT password to LDAP, how did you create it? I do not know what the warning in the radiusd.conf file about needed 0x in front of the hashed NT password means. It has never impacted me. I am running Samba 3.0.3 (the one the ships with Fedora Core 2) with its password backend configured to be LDAP. I use smbpasswd to set the passwords. When I look at the passwords in the LDAP database, I do not see a 0x in front of the hashed NT password. However, my users are able to authenticate using PEAP / EAP-MS-CHAPV2. I currently use the smbldap-tools to add/mod/remove users and workstation in the ldap. It works fine but this comment in the radiusd.cond and a post from Alan Dekok in reply to one of my problems with radius+ldap made me think something was wrong ... i still can't auth against the ldap using radiusd. I switched to another project right now, cause this gave me some much headache that i gave out and i'm still using classical tiki/wpa on the access points .

Re: radius, 802.1x, eap/tls, and edirectory (ldap)
It looks like maybe the 0.9.3 version of freeradius does not support TTLS. Is this correct? If so, does the CVS version include support? Sorry if this, too, is documented somewhere, but I just thought I'd ask while I was here. I grabbed compiled the CVS few hours ago in the goal to make TTLS+mschapv2 and it crashes when i launch radiusd, saying that it can't find the rlm_eap module . .. Anyway, just for my information (still trying to get my auth working ..) are you using a supplicant like aegis, or just the one provided with your wifi card ?

Re: radius, 802.1x, eap/tls, and edirectory (ldap)
I'm also a total newbie in wifi world =) spent 4 days on this auth thing and can't get it to work yet .. i'm not using Novell LDAP, it's an openldap with all our users infos in it: windows passwords without the 0x in front of the passwords (tried to add it manually, result is that i can't log in on a workstation after that), and unix encrypted passwords. I'll test the Aegis supplicant tomorrow, will post the results .. This is my first attempt at anything wireless (as you may have noticed by my previous posts), so I haven't had much experience with the various supplicants out there. I think you can get a fully working demo of Odyssey (double check that) from Funk Software...it's supposed to do TTLS, plus some other cool stuff with Novell Client signons. We'll see.

Re: FreeRadius/LDAP conf : little problem
Hello again,
Thanks for your help, it works great now ... just did what you told: an ldap
user who got read access on all fields/users of the directory.
Problem now is that i have to enter the encrypted version of the password in the
username/password popup window. The userPassword field in the LDAP entries are
encoded with the {CRYPT} salt. Is there a way to configure/hack FreeRadius to
tell it to crypt the password before the comparison against the password the
LDAP authorize section returns from its query ?
If not possible, i have no idea how i could use in real world the 802.1x auth :
-( I just can't decrypt all passwords in the directory and put them back in
cleartext ...
Thanks for your great job, and your support.

Re: FreeRadius/LDAP conf : little problem
Ok, please forget my precedent message, i've just re-read aaa.txt and it's said
that the AP sends an hash of the password it receives from the supplicant. No
way to make freeradius crypt it it would not have any sense ... now that i'm
lost in all those auth protocols, i don't know what to do ...
is there a way to make the auth against the ntPassword field stored in the LDAP
instead of the userPassword wich use the {CRYPT} salt ? I am currently
generating certificates to use TTLS/PEAP ...

Re: FreeRadius/LDAP conf : little problem
Hi again Alan,
Configure the password_header entry in the ldap{} section, in
radiusd.conf.
already done, but in the doc it's said it just strips away the {CRYPT} substring
of the crypted passwd. Still have to put the encrypted password in the popup box
to make it work...
You can also map that LDAP entry to the Crypt-Password
attribute, and the server will figure it out from there.
Also tried it:
checkItem LM-Password lmPassword
checkItem NT-Password ntPassword
checkItem Crypt-Password userPassword
checkItem SMB-Account-CTRL-TEXT acctFlags
But it doesn't seem to change a lot of things:
rlm_ldap: Adding userPassword as Crypt-Password, value { op=21
rlm_ldap: Adding ntPassword as NT-Password, value
EFAC11B52777F8D7A34BDC1A0F89228D op=21
rlm_ldap: Adding lmPassword as LM-Password, value
136BE46417241D68AAD3B435B51404EE op=21
rlm_ldap: looking for reply items in directory...
I tried it with and without setting the password_attribute and password_header
in the radiusd.conf. Result is the same. Anyway in the freeradius sources i
can't find any reference to Crypt-Password in the rlm_ldap module, and in main.c
it seems to be a reference to a user-provided password, not to the backend db.
I'm using 0.9.3 do i need a CVS version ?
Thanks again

Re: FreeRadius/LDAP conf : little problem
That shouldn't be necessary.
well i'll double check tomorrow, i've done so many tests so far that maybe it's
not usefull anymore .. I know for sure that in debug logs, it shows the password
grabbed as {CRYPT}xxx.
rlm_ldap: Adding userPassword as Crypt-Password, value { op=21
That value doesn't look like a password.
yes i know, and i think that's the problem. When i just use password_attribute
it grabs the whole password (displayed in debug logs), and not anymore when i
use the mapping for Crypt-Password, of course on the same ldap attribute for
both. i thought the '{' displayed was from the first caracter it met ( from
{CRYPT} ) so i tried to re-enable the password_header field in the ldap
section of radiusd.conf, without any good result.
That value should have a 0x in front of it.
That's what is told in the radiusd.conf yup .. could that change something to
the rest of the problem ? I'll check the smbldap-adduser.pl script i use to add
windows users in the ldap tree. Anyway windows workstations work perfectly
without the 0x.
LDAP doesn't do crypt'd passwords. The server does. And the server
doesn't care where that crypted password came from.
Yup, but i was trying to find the moment where the radius Crypt-Password
attribute was used in the ldap mapping file and from the ldap directory, to
check why it doesn't grab the password from the user entry.

FreeRadius/LDAP conf : little problem
Hello
I'm facing some kind of configuration troubles with freeradius and openldap. I
got a new Access Point wich i'm trying to use with 802.1x auth.
I'm using a classical samba/qmail LDAP schema so that users in the company can
authenticate against ldap with win/linux workstations. Basically, i got 3
password fields, lmPassword, ntPassword, and userPassword . All of them are
encrypted and, there is no 0x in front of the ntPassword.
The ldap section in radiusd.conf seems to be ok, the connection is done, and ive
set the password_attribute to userPassword and later to ntPassword to check
if it changed naything to the problem (no).
Other sections i'm using:
authorize {
preprocess
auth_log
ldap
eap
}
authenticate {
eap
}
now, when i set up a 802.1x client, the AP connect to the radius server and here
is the debug output:

Re: FreeRadius/LDAP conf : little problem
Then you can't do CHAP or EAP-MD5, which is basically CHAP. Yup. EAP-MD5 doesn't work.

LEAP returns the same error with the missing User-Password attribute .. And i can't store clear passwords in the directory I'll paste the ldap section in one hour, i can't have access to it at the moment .. -- Arnauld Dravet - List info/subscribe/unsubscribe?

Re: FreeRadius/LDAP conf : little problem
Selon Alan DeKok [EMAIL PROTECTED]:
Something other than EAP-MD5.
LEAP should work.
As an alternative, you could try storing NT passwords. That will
allow LEAP MS-CHAP to work.
okay i'm not really into Win stuff .. ntPassword fields seem crypted since i
can't read them with my eyes, but i think it's just a hash or something. Isn't
it the regular way to store NT passwords ?
anyway, here is my ldap section in radiusd.conf:
ldap {
server = 192.168.1.6
basedn = ou=Users,dc=mtp,dc=epsi,dc=fr
filter = ((objectclass=posixAccount)(uid=%u))
start_tls = no
dictionary_mapping = ${raddbdir}/ldap.attrmap
ldap_connections_number = 5
password_attribute = ntPassword #--- i changed this one just to try it out,
it was originally userPassword
timeout = 4
timelimit = 3
net_timeout = 1
}
and here are my sldapd access rules:
access to dn=.*,dc=mtp,dc=epsi,dc=fr attr=userPassword
by dn=cn=root,dc=mtp,dc=epsi,dc=fr write
by self write
by * auth
access to dn=.*,dc=mtp,dc=epsi,dc=fr attr=ntPassword
by dn=cn=root,dc=mtp,dc=epsi,dc=fr write
by self write
by * auth
access to dn=.*,dc=mtp,dc=epsi,dc=fr attr=lmPassword
by dn=cn=root,dc=mtp,dc=epsi,dc=fr write
by self write
by * auth
if i remember well (long time i've not reconfigured openldap) the write perm
also allow read ?
since i didn't configure any user in the ldap section of radiusd, isn't it
supposed to log in the ldap server with the username/passwd received by radiusd,
and grab the user password which should be possible since it has write (read ?)
perm ?
thanks for your help
