    Question Troubleshooting samba authentication problems

    Hello all,

    I'm a fairly novice server administrator but have several Ubuntu 12.04.2 LTS x64-based samba servers set up at my work, which generally are performing very well. However, there's one share which won't allow non-guest access for some reason, and I'm having a heck of a time figuring out why.

    In smb.conf, I have

    security = user

    set, and the following share definition:

    Code:
    [accounting]
        comment = ATS Accounting File Server
        path = /srv/falcon/accounting
        browsable = yes
        create mask = 0755
        guest ok = no
        read only = no
    I've added a couple of users by first creating unix accounts, then following the directions in this guide:

    http://www.howtogeek.com/howto/ubunt...ser-on-ubuntu/

    If I set

    guest ok = yes

    in smb.conf, then I can access the share just fine. However, with guest ok = no, I get the following error in Windows when trying to access the share after providing correct login credentials:

    \\falcon\accounting is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions.

    Just to be sure unix permissions aren't the problem, I temporarily have everything set wide open (0777) in the /srv/falcon/accounting directory and sub-directories. Things seem like they are set up just like another share (on a different server) which is working properly, so I can't figure out what's wrong. How can I troubleshoot further to figure out what the problem is?

    Thanks!

    Re: Troubleshooting samba authentication problems

    Moved to Server Platforms.

    Are there other shares on this server that are working properly?
    (Is problem limited to one share - or is this the only share?)

    Re: Troubleshooting samba authentication problems

    Hi Iowan,

    Thanks for the move; I wasn't sure the best place to post this question.

    There is one other share on the server (actually the main share provided by this box), but it's by design open:

    Code:
    [projects]
        comment = ATS General File Server
        path = /srv/falcon/projects
        browsable = yes
        create mask = 0755
        guest ok = yes
        read only = no
    It works very well, but of course authentication issues don't come into play!

    Re: Troubleshooting samba authentication problems

    You may not have the desire to experiment - otherwise, I'd ask if [projects] loses access with guest ok = no. I'm also curious if you can log into the server as one of the users you created.

    I tried that and was unable to access the share even after providing credentials, just as with the accounting share.

    I'm also curious if you can log into the server as one of the users you created.
    Yes I can, but there is a clue that appears on login:

    Code:
    Could not chdir to home directory /home/rbiggs: No such file or directory
    /usr/bin/xauth:  error in locking authority file /home/rbiggs/.Xauthority
    I haven't pondered yet the implications of this... I used sudo useradd to create the user accounts; did I miss something?

    Did you add the appropriate samba users with smbpasswd -a <user>? Besides the Linux user you need to have the Samba users in the Samba database.

    You can see who has been added with this
    Code:
    sudo pdbedit -L
    This lists the contents of the Samba user database.

    Yes sure did, here's the output of pdbedit -L:

    Code:
    nobody:65534:nobody
    falcon:1000:Falcon
    rbiggs:1002:
    kari:1001:
    rbiggs and kari are the two users I added. I also added a samba user for the "admin" account, falcon.

    From the Ubuntu terminal post the output of this (login with a user when asked)
    Code:
    smbtree -d3

    Hi redmk2,

    The output of smbtree -d3 that seems to pertain to the server in question shows:

    You must be using the command from the computer named FALCON. This shows a problem networking problem right off the bat. The IP address 127.0.1.1 is only seen by the local host. So this machine is misconfigured. Hopefully you have a wired Ethernet card and a fixed IP address for that NIC. Post the output of this:
    Code:
    ifconfig |grep inet

    The following is the complete output, some of which is obviously from other shares, servers, and workstations:

    The command smbtree lists ALL of the CIFS servers on the LAN (both Linux and Windows) What you see is all the errors from all the machines.

    I think that the best way to handle all of this is to establish one successful Samba server. How many of these are Windows machines and how many are Linux? Do you control all of these (administrator)? Falcon may be the easiest one to fix once I know that the address is fixed and it is in the IP network of 192.168.0.0 /24.
