[SOLVED] openLDAP/Samba authentication from XP issue

[erolleman]

I have openLDAP and SAMBA running on ubuntu server 7.10 . I have samba configured to use ldap as it's database back end. The problem is that when I am on the Windows XP machine and I try to join the samba domain or just try connect to the share with the username and password it just tells me that the username and password is incorrect... Could someone shed some light on this situation for me?

I'll post config files if necessary.

Thanks.

Try adding the machine first:


smbldap-useradd -w machine_name$

Then try joining the domain in the typical fashion on your XP setup.

[erolleman]

Thank you for the suggestion. Unfortunatly that didn't work. I didn't add the machine account to start with because I thought SAMBA would to it automatically, because of the " add machine script = /usr/sbin/smbldap-useradd -w %u " line added into the smb.conf file. If it helps you understand my issue a little bit more: I can't authenticate just to access a share either. The error I get from either trying to access a share or join the SAMBA domain is " Logon failure: unknown user name or bad password. ". I have linux authentication to openLDAP working fine. I can create a user then login with ssh or locally on the ubuntu server with that user, so I know that isn't the issue. The problem seems to be getting SAMBA to authenticate.

Any more insight?

Try that command and see if you have the object sambaSamAccount
and then check to see if you have sambaSID object. Without those two even if you are passing the the correct Username and Password, you will still get the user or password error joining a domain.

It may be an error in my samba configuration that my add machine script isn't doing this automatically. I have not investigated.

What is your domain name?
How are you accessing the share?
I'm assuming you get a "connect to yourserver" where you specify the username and password. What are you putting in for the username?

a user then login with ssh or locally on the ubuntu server with that user, so I know that isn't the issue. The problem seems to be getting SAMBA to authenticate.

PAM may be binding to LDAP fine.
Samba may not binding OR it is binding fine AND keep in mind that:
You will be accessing different attributes from different schemas in either authentication from a Linux host versus a Windows host.



Any more insight?

To solve your problem? Yes.
Some insight as to the account you're using to authenticate from your directory, your smb.conf configuration, and slapd.conf configuration.

Remove any password hashes as necessary.

[erolleman]

Okay, here's the dn entries exactly as they exist in both slapd and smb for my directory admin account:
slapd: rootdn "cn=diradmin,dc=test"
rootpw {SSHA}EnoWIMQNwMUslbzj+n5xLqiJG/9jjbv
smb: ldap admin dn = cn=diradmin,dc=test

I then ran " smbpasswd -w pass " to update the password into samba's secrets file (Yes the password I'm using is " pass ", it's a virtual test environment so it doesn't matter to me if you know the password).

The root account information as created by the smbldap-populate command is:

When I try to join the domain I used " root " and pass, I also tried " TEST\root " and " pass ". When I try to just access the shares I go " \\ldap1\netlogon\ " in the run command and it prompts me for username and password to which I try the same combos when trying to join to the domain with no success.

[promodus]

If you are able to post the samba smb.conf and your ldap slapd.conf file I may have a better idea. I'm not sure if SAMBA is binding correctly or not.

It sounds like part of smbldap-tools is working, your ldap server is running. I'm not sure if the proper samba objects are properly put into your DIT (http://en.wikipedia.org/wiki/Directory_Information_Tree)

Is there a space in sambaNTPassword, just before the d?

[erolleman]

No there isn't. When I saw that space after I posted I checked, haha. Some wierd thingy the the post in the forum added.

Two things I've noticed:

passdb backend = ldapsam:ldap://ip_or_dns_of_ldap1

/usr/sbin/smbldap-passwd %u

[erolleman]

So I feel pretty dumb about forgetting the " ldapsam:ldap:// ".
My issue now is that when I try to join the domain I get the error message " The following error occured attempting to joing the domain 'test'; The network path was not found."

I have set up bind and created the corresponding master zone (test) and created a host record for ldap1. I run " nslookup ldap1 " and it auto appends the .test (I configured the suffix) and resolves fine. I also tried " nslookup ldap1.test " and " nslookup 192.168.0.253 " which both resolved correctly (I created the reverse lookup zone as well). I'm not sure where it's failing to find network path. It even fails when I try to just connect to the share fromt he run command.

Any help?

[promodus]

wins support = yes

Something to try:
On your XP Clients set the WINS server to the IP: 192.168.0.253 (your samba pdc)

[erolleman]

Yeah... I had that setup, but no luck. Don't suppose you have any more ideas do you?

[promodus]

A couple ideas.

ldap user suffix = ou=users,dc=test
In your directory, within the users OU what users do you have?

When running this command on your server:

net user

Do you see any users that are from your users OU?

[erolleman]

Okay here's my current status: when I try to join I get the error: "The user name could not be found.". Wierd thing is that I have no problem authenticating with that same user account to view shares (the user account being " root "). So I'm stuck once again. When I do a " net user " I get the following info:
root
nobody
user1

When I do a " net group " I get the following info:
Domain Admins
Domain Users
Domain Guests
Domain Computers
Users

And some ldap information about root, Domain Admins and the machine accound I created manually to see if that will work:

I hope this is enough info for any samba + openldap guru's to provide some assistance.

Thanks.

[promodus]

Could you

net getlocalsid

I'm thinking your domain sid may be too short.

Secondly for your computer object

add

objectClass: sambaSamAccount

onces that's added, also add:

sambaSID, sambaAcctFlags and sambaNTPassword

I don't know why smbldap-useradd did not add those.

[promodus]

Sorry your SID should be fine.
"SID is in a standard format (3 32-bit subauthorities preceded by three 32-bit authority fields)." As quoted from:
http://technet.microsoft.com/en-us/sysinternals/bb897418.aspx

I believe your problem is, when trying to join the domain, samba is trying to modify the attributes for ldap-xp$ but since they are not there it says account not found.

It in fact finds the account you use to authenticate, but does not find the account for the machine (ldap-xp$).

[erolleman]

Okay I think I figured out part of the problem I put the computer account (ldap-xp$) into " ou=users,dc=test " and now I get a different error which reads " A device attached to the system is not functioning. "

[promodus]

What do you get when:


net lookup name ldap-xp$

[erolleman]

I get:

S-1-22-1-10004 1 (User) UNIX USER\ldap-xp$

[promodus]

The SID should be longer.

The output I recieve:

S-1-5-21-2077956632-1721461777-1151864052-1001 1 (User) mydomain\computername$

Check the attributes associated with this LDAP Object.

[erolleman]

I can't seem to figure out why smbldap-tools doesn't create the proper SID for the computer account. I works for creating users... Am I missing something?

*I edited the "computersdn" to be "ou=users,dc=test" because samba seems to only look for the account in the users OU and not a separate computers OU.

Discrepancy:
Your smbldap.conf


computersdn="ou=users,${suffix}"
your smb.conf:

ldap machine suffix = ou=computers,dc=test

your smbldap.conf


idmapdn="ou=Idmap,${suffix}"
your smb.conf

ldap idmap suffix = ou=idmap,dc=test

I would change the case Idmap to idmap in smbldap.conf.

Thanks, it's working now. Down right awesome!

Do you mind if I piggyback on this thread? I'm having a somewhat similar problem. When I try to join a XP client to a domain run by a openLDAP/Samba server (Ubuntu 8.04), I get "The network path was not found."

Going though the thread here I see I have a few problems:


When I do a "net user" or even a "sudo net user," I am prompted for a password. When I enter either my "root" account's password or the password for cn=admin,dc=sander,dc=local (yes they are different), it says "Could not connect to server 127.0.0.1 Connection failed: NT_STATUS_CONNECTION_REFUSED." There is a root listing in the LDAP database, but my actual username is "swsander". "net group" or "sudo net group" result in the same thing.
When I do "sudo net lookup name winxptest$", I get "S-1-22-1-30000 1 (User) UNIX USER\winxptest$" This was pointed out as a problem on page 2 but I didn't see where this was fixed.


One thing that might throw a monkey wrench into all this is I have two DNS servers and two Samba servers (though only one is set up as an openLDAP + Samba domain controller... the other one is acting like a simple Samba workgroup file server).

Help!

[scottws]

Here is the "net user" error:


swsander@userver:~$ sudo net user
Password:
Could not connect to server 127.0.0.1
Connection failed: NT_STATUS_CONNECTION_REFUSED

I don't know what this password could be as there are only three passwords I've used on this box for anybody for anything and none of them are accepted.

Edit: I tried the "net user" command (as root) on my Debian 4.0 Etch Samba file server. This is a standalone server, not a domain controller, and I built it a few years ago. Well... the same thing happens on that server as well. I'm starting to think my problem lies somewhere else, but where I have no idea.

Here is the computer error:

Here are the attributes for the problematic (?) computer account:

I created that computer account with the command "smbldap-useradd -w winxptest." I'm not sure what's up, because smbldap-useradd works just fine.

Edit: According to this link (http://fixunix.com/samba/140308-samba-smbldap-useradd-not-creating-machine-accounts-correct-fashion.html), the correct SID information is generated when the client joins the domain. I'm thinking I can't get it to join due to some problem related to the problem I'm having with the "net user" and "net group" commands. What I don't get is I have no trouble with commands like "net getlocalsid," or logging into PhpLDAPadmin and manipulating the database there, or creating user accounts with smbldap-useradd (which can be logged into on the server).

Ok. It's definitely an authentication issue.

If I type the domain as anything but "SANDER," I get a response that the domain controller could not be contacted. But if I do put "SANDER" for the domain, I get a password prompt for a user with credentials to join PCs to the domain. So it's seeing the openLDAP+Samba server, but I just can't get anything to authenticate.

No matter what computer name (pre-staged in openLDAP or not) or login credentials I type in, I get...


The following error occurred attempting to join the domain "SANDER":

The network path was not found.

So it's definitely failing on the login part. The guide I'm using (http://www.howtoforge.com/openldap-samba-domain-controller-ubuntu7.10) says that the user "root" (who does exist in my openLDAP database somehow) should have the ability to join computers to the domain. Well it wasn't working. I tried "smbldap-passwd root" and typing in a new password, but this did not solve the issue.

I'm pulling my hair out over this one! I've gotten it working before on a previous build (admittedly, Ubuntu 7.10 Gutsy Gibbon instead of Ubuntu 8.04 Hardy Heron).

Ok, I solved it. It was one of two things:


WINS: I saw another post on the Internet where someone was having a similar problem. It was actually much older (Samba pre v3 and Windows 2000) but the problem was identical. Users recommeded he disable WINS.
Samba wasn't started: After I did "wins support = false" in /etc/samba/smb.conf, I did "sudo /etc/init.d/samba restart" and was greeted with this lovely message: "start-stop-daemon: warning: failed to kill 5646: No such process." It seemed to start ok, but I repeated the command just to be sure and it worked ok that time. So it's possible that Samba wasn't running properly this whole time.


In any case after doing both of these things I was able to join the domain.
