Question

NT_STATUS_LOGON_FAILURE with Samba users

Asked by: klukac

I got feedback from the Linux users group on making a samba password file in /etc/samba, then adding users - that was helpful, because I had been looking for that in the Samba documentation and couldn't find it.  I'm working with Samba as packaged with the Linux RedHat 8.0
rpm-qa | grep samba shows samba 2.2.7-5.8.0 plus -client and -common, so it doesn't look like anything is missing.

Unfortunately, when I try to connect to my linux client with smbclient //hostname/username, I get NT_STATUS_LOGON_FAILURE after typing the user password

testparm shows no errors, and smbclient -L hostname shows local shares on my linux box -
when I type the root password at the prompt to see local shares, the root password is accepted.

But the user passwords are rejected. Tried rebooting, also installed webmin - assume there's a sync problem somewhere, but webmin has way more features than I'm prepared to use right now.

Also tried installing swat
I created a swat file in xinetd.d and added/enabled tcp port 901, but the server path in the swat file is not correct - I couldn't find a bin directory under samba, not sure why.

I feel a long way off from connecting to other PCs on my LAN, help out if you can :)

In your /etc/samba/smb.conf file do you have:

security = user
encrypt passwords = yes
smb passwd file = /etc/samba/smbpasswd

When you created the SMB users with smbpasswd did you match the Linux user names and passwords?

 

by: pjedmondPosted on 2003-08-30 at 02:49:22ID: 9253542

One possible cause of this is that fact that you have given null passwords for the users that you are trying to use.

Try adding:

Allow null passwords

to the global section of your smb.conf

The other cause of this problem is that samba is trying to authenticate against a windows Domain Controller, and that the windows domain controller is not available. Check that your smb.conf is not trying to do this.

HTH:)

 

by: pjedmondPosted on 2003-08-30 at 02:56:47ID: 9253551

If you want to start again from scratch with your smb.conf you could try:

First lets deal with your being able to see the linux box from windows:

First find the samba configuration file. It will be :
/etc/samba/smb.conf
or /etc/samba.conf

It will have a [global] section followed by [***} sections for each share that samba provides. Hopefully even some examples:)

In the global section add:

remote announce = 192.168.0.255/WORKGROUP # Announce to all PCs on the 192.168.0.* subnet that you exist and are a member of WORKGROUP
netbios name = MYLINUXBOX      #So that everyone knows what it's called



Try adding this entry after creating 'mkdir /var/public', and 'chmod 777 /var/public'. It creates a share with virtually no protection/security. Once you get it working, then ou can start enhancing it to your requirements.

[public]
      path = /var/public
      comment = Public Folder
      public = yes
      only guest = yes
      force directory mode = 777
      delete readonly = yes
      create mode = 777
      wide links = no
      force create mode = 777
      directory mode = 777

This is a folder readable/writable by everyone.

Now restart the samba server '/etc/init.d/smb restart'

And try browsing from windows.

Now for windows browsing from Linux:

First create a mount point 'mkdir /mnt/winshare'
Now mount the share:

mount -t smbfs -o username=myname,password=mypass //winpc/testshare /mnt/winshare

If DNS isn't set up for this pair then you will need to replace the 'winpc' with the appropriate ip address.

mount -t smbfs -o username=myname,password=mypass //192.168.0.5/testshare /mnt/winshare

You should then be able to browse the /mnt/winshare directory.

GOTCHAS:

Windows/linux interaction suffers from case sensitivity problems therefore:

a.   Keep all usernames lowercase.
b.   Keep domain names all upper case.

Windows XP and 2000, require a seperate smb account for the PC as well in order to enable samba to cope with the complexities of the authentication process. This additional account is the name of the machine followed by the $ sign. So if the PC is called mypc, then the samba account required is mypc$

Hope that helps:)

I use webmin to configure my samba conf file. Try that http:\\www.webmin.com

Thanks

 

by: pjedmondPosted on 2003-08-31 at 04:06:16ID: 9256707

Webmin does not provide full access to all of the smb.conf information. It will not delete anything in there that you've already inserted, but the overall GUI element provides access to only certain limited funtionalities.

However, within webmin, you can edit the config file directly by going to 'Others' in Webmin an adding a custom file editor for:

/etc/samba/smb.conf

After that you can just click on this to edit the file.

The same principle applies to many of the other webmin modules - the GUI bit provides all the common requirements, not some of the advanced functionality, and the rest of the capabilities can be obtained by editing the file directly.

 

by: pjedmondPosted on 2003-08-31 at 04:07:35ID: 9256712

HEALTH WARNING  - Messing up files is fairly easy if you decide to edit them directly - Do a cut an paste of the fiel from webmin so that you have a backup....just in case:)

pjedmond's advice got me into the linux box from windows 2000, thanks very much
I'm still working on the bugs:
the valid users parameter on a share cuts me off from the folder -  there's no way I can log into a directory with it.  the error on windows reads: the credentials supplied conflict with an existing set of credentials
The /var/log/samba log file for my linux box reads log error: passdb/pdb_smbpasswd.c: getsmbfilepwent (344) getsmbfilepwent:
malformed password entry (no :)
Did some more checking,
smbpasswd command works the first time, when I'm adding a user which I've just added in unix, but when I try to change the password later it fails.  also couldn't change the root password for samba
So the only way I can achieve a windows connection to my linux box is to type in the root password that I'm using to administer linux, and that's not an optimal solution.
I created users with current defaults - each user is created with his own group.  I did a chmod on the home directories to 775, that didn't help, and looked at the documentation on how RedHat does user authentication.  Except for the PAM directory, it looks like Unix, but there's a lot I don't know about how it or PAM works. I'm digging thru /var/log to see what I can find

 

by: klukacPosted on 2003-09-12 at 06:50:09ID: 9345825

Comment for the record since I closed this.  I restarted the named daemon after fixing an error, and now I can log on to the linux box from windows 2000 without using root password - the user log-on gets me to the home directory.  So I'm really happy about that.  Still can't get linux to see windows - I get an error on mount and need to study its syntax to mount the share - but I'm confident that I'll get there eventually.  Thanks pjemond for all the info - getting samba to work has always been tricky in my experience.  

 

by: pjedmondPosted on 2003-09-12 at 07:32:05ID: 9346117

You may wish to investigate mount, as it can also be used for accessing shares:

 mount -t smbfs -o username=tridge,password=foobar //fjall/test /data/test
