Ubuntu Networking :: Samba User Authentication Stopped Working?
May 20, 2011
I have installed Samba 1.2.63-0Ubuntu4 (system-config-samba) on Ubuntu 10.04, and it has been working without any issues for a few months now, but now the username/password authentication does not work anymore and I can't figure out why
I have tried changing username/password(thinking maybe i forgot the correct credentials) and the new username/pass does not work either.
I have also tried "sudo service smbd restart" in terminal to restart samba but this does not work either
I can still see visible shares when browsing server via "network neighborhood" on XP,,, and can access the shares that do NOT require authentication
username/password are made up of standard characters as well

Been searching for hours and looked at several other threads but still can't figure this out. We have 4 folders being shared from a Ubuntu 10.4.2 LTS Server using Samba. A couple days ago two computers in the office lost access to these shares. The other computers in the office are fine. So far as I know nothing has changed on the server. I can putty into the server still but I can't map a drive or open a window through run (\server_nameetc).
I've also tried disabled iptables on the server and windows firewall on the the windows xp machines. Still no luck. What am I doing wrong? Like I said, so far as I know there have been no changes to the server whatsoever. One day it was working and the next it just stops.

I'm trying to utilize my company's IT orginazation's LDAP service (running on some sort of windows) for authenticating users on an Ubuntu box.Another group has done something similar for CENTOS; I've used their ldap.conf as a reference as well as ap-server.html (LDAP Authentication section)I can't get it to work. When I try to connect as my corporate user I see this in auth.log:
Code:
Jan 14 14:32:24 Algalon sshd[7062]: nss_ldap: could not connect to any LDAP server as cn=ldapquery2,cn=Users,dc=<companyname>,dc=com - Can't contact LDAP server

I'm running Maverick Meerkat 10.10 x64, and I'm trying to set up a Samba share with user security. In other words, when accessing the share, I want to be prompted for my username and password. Everything in my smb.conf file looks ok to me, but the shares are still accessible with no user security, and I don't know why. The smb.conf file is below:

how to make a new Ubuntu 9.10 box use our LDAP/Samba server for user authentication. Our Red Hat and Windows machines all use it just fine. I've been trying to use the auth-client-config and libnss-ldap packages for this purpose, but I must be missing something. I'm pretty green with LDAP, so this is my first time diving in... Is there a good How-To or step-by-step read on this? All of my searches lead me to setting up Ubuntu as the server, and that isn't what I want. I've also tried the steps listed in [URL] for the LDAP Authentication section.

I was SSHd into my laptop which is right next to me, then it lost battery power and turned off. When I switch it on, I can't FTP, SSH into it and the Network Drive (Samba) won't work.

I recently upgraded to 11.3 and must say am highly disappointed. Between the multitude of problems, and sudden lack of long standing tools ( Sax2, system repair, loss of functionality in software installer), this to me has been a major step backward.
Now I have found out Samba as well has stopped working, sort of. I can still copy from windows share to my Suse box, however copying from Suse to the windows share now results in an error, the details for which just say invalid argument. Also note there are no logs in /var/logs/samba so I don't really have a clue whats happening.

I run Samba version 3.4.7 as a Domain server for our company, and recently we reorganized our IP-addresses. And the Samba server also got a new IP-address. (192.168.1.60 -> 192.168.1.22). However, now new computers can not join the domain, and old ones can not connect to it correctly (they get a temp profile).
Windows XP gets a temp profile when connecting, and when trying to join a domain I get this error "A domain controller for the domain HAWAR3 could not be contacted. Ensure that the domain name is typed correctly. If the name is correct click Details for troubleshooting".
When trying to connect Windows2008R2 (already a member) it says:
"There are currently no logon servers available to service the logon request."
My guess is that is is some problem with WINS or something.

Whenever I try to install something with apt-get, I get a list of errors. Most of the time, the package I want to install gets installed anyway. However, this time samba stopped working, and I discovered that it was no longer on my system. I'm not sure how this happened - I haven't tried to remove it. So, I tried to reinstall it with 'apt-get install samba'. This time, the package did not install, and I got a long output from the terminal:

I'm running 10.04, typically using the default gnome session. I locked my screen overnight, and when I came back the keyboard wasn't working. Before anyone asks, yes it is still plugged in. Here's where it gets weird. I logged out using the mouse, and switched to another user on the system, and it works fine. I have keyboard input on the gdm log on screen and for other users. I've tried about every possible combination of logging on/off and rebooting and nothing seems to work. Is this an Xorg thing or a gnome thing? Any ideas what to do from here? I can still get to a terminal through another user and then "su" to my user so I can run "sudo" commands. So in other words, no need to bring in a live CD or a clean install at this point, but I don't really know where to start with this one.
UPDATE: I switched session types to LXDE, and the keyboard DOES work for my user. However, when going back to gnome it still doesn't work. I guess that seems to point towards it being a gnome thing, not Xorg.

User switching doesn't work for me anymore since upgrading to Lucid. When I choose "Switch From <user>..." in the logout menu on the top-right of my screen, it jumps to the login screen (gdm) but it doesn't show any usernames as it should.I wish I could get a screenshot of gdm but I'm not sure how.

I ran "yum update" on 03-06-2009 and it updated my samba version from
3.2.8-0.26.fc10.x86_64
to
3.2.11-0.30.fc10.x86_64
My network shares then became read only!After some digging it turns out my system is not working because of Samba bug 6291, the "force user" option is no longer working.
Ideally I would run another "yum update" and that would fix the problem. Apparently the bug has been fixed in Samba 3.4.0pre2 - when can when we expect that to be released and included when I do a "yum update"?
Alternatively how do I get back to version 3.2.8-0.26.fc10.x86_64 ?

Kuser no longer works for 'rob' but still works for 'robert' & 'root'. It launches (i.e. the cursor bounces up & down and a Kuser box appears in the task bar) but the Kuser screen never opens. Finally, the bouncing cursor disappears as well as the Kuser box in the task bar.

I haven't used my VB for a few weeks however all of a sudden it refuses to work for my normal non-root user. It's almost as if it can't find libraries in the /opt/VirtualBox directory. Initially it refused to start completely so I linked the required libs into /usr/lib64 ( yip real hack. Then it started but a vm would not start, and comes up with an error about a missing lib again which is definitely there. My non-root user is in the vb group and nothing besides system updates has changed. vb 3.2.10 slack64-current.

I have been able to accomplish my goal of creating an AD-like authentication using LDAP,SAMBA and LAM. From what I have seen you can have this type of setup but it doesn't allow the passing of group policies to the desktops of the users.

So far I've been able to get Samba to connect to the my WORKGROUP and I can see my Vista PC as well as my 3 hdd's but when I try and open the folder, any folder, C$; D$; or E$ I'm confronted with a user name and
password prompt. No user name or password combination that's associated with either machine, openSUSE or Vista will grant me access. Why am I seeing this prompt and what I would really like to know is can it be
disabled all together? Otherwise, what user name and password does Suse want? Do I need to tell Suse in a terminal a user name and password?

When originally installing 11.04 I had problems getting my Ralink 5390 wireless card to work.
Today my computer froze completely and I had to turn it off via the power switch. When I turned it back on, wireless was no longer recognized! My iPod can connect to the network just fine, so it must be an Ubuntu problem. There are no problems with my ethernet connection either.
I researched this and found several threads about blocking and unblocking wireless devices using the rfkill command. Well, unfortunately for me the rfkill command doesn't work. When I type sudo rfkill list or sudo rfkill unblock all, nothing happens; it just returns me to my bash prompt. I even tried uninstalling and reinstalling rfkill...nothing.

I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.

My work has got a new Sharp MX-1800N network printer. The setup requires user authentification, one password for printing b&w, another for printing color. However when they try to set up my netbook running ubuntu desktop 10.04 they don't get it to prompt for a password, which makes the printer reject the printout. How do you fix this?

Wired and wireless networking have been working flawlessly for years on my HP Compaq 6710b laptop. Several weeks ago, after an automatic update via the update manager, my wired network stopped working. I did not notice it directly, since my wireless connection took it over. I only noticed it when I had to work in an office where I didn't know the wireless password.Since then, I have been trying several things and searched several forums. It is hard to find any troubleshooting information about wired networking, as most of the problems seem to occur with wireless.
I did verify that there is no hardware problem. My laptop is dual boot and when I boot the other operating system, the wired network works without problems (as does the wireless.)My Ubuntu version is Ubuntu 10.04.1 LTS. My kernel version is 2.6.32-25-generic i686. I hope anybody can help me getting my wired network working again.

pulled the wireless USB adapter out of the back of my laptop when I was using it. I plugged it back in and it can see my wireless network, but it can't connect. Everytime it tries, it just shows the connecting icon on the top bar for a few minutes and then says that the network has been disconnected.
I've tried uninstalling and reinstalling the USB adaptor, but nothing I've done seems able to fix the issue. Anyone know how to fix this?
The USB adaptor I'm using is a Trendnet TEW-424UB

I have a Thinkpad T400 notebook that dual boots windows 7 and Ubuntu 9.04. My wireless has worked both in windows and ubuntu for the past several months. However 2 days ago, the wireless in ubuntu stopped working. I think this may be a result of trying to set up a static eth0 connection between my laptop and an embedded board, but I dont see how messing with eth0 would stop the wlan from working.
Symptoms: When I left click on the network connections icon in the tray, all it lists under "Wireless networks" is "device not ready". Needless to say, there are no networks available to connect to. Also the wireless is working fine under windows.

Last night I was trying to get my printer working, and when I rebooted, I lost networking and sound.I am currently booting on a live CD, and sound and networking are fine-- so it can't be a hardware issue (obviously). I must have inadvertently broken something, but I can't figure it out.I have tried restarting networking, but it doesn't respond-- it says stop/waiting or something like that.I can't access the sound preferences-- it says waiting for sound to respond (or something like that).
When I reboot, sometimes I see a terminal window with the same line scrolling very, very quickly-- something about waiting for USB. Additionally, the system is very slow to respond-- clicking a menu item can take a long time for it to appear, etc.What could have occurred, and how might I troubleshoot it?
