Samba version: Version 4.1.17-Ubuntu

Ubuntu 15.10

When accessing a Samba share in windows, I can see the share but whenever I try and access it - entering the same username and password as the Samba user created with sudo smbpasswd -a benjamin (same as system user), I only get "Access is Denied". Here are my smb settings

[global]
server string = %h server (Samba, Ubuntu)
#encrypt passwords = No
map to guest = Bad User
obey pam restrictions = Yes
passdb backend = tdbsam
pam password change = Yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
unix password sync = Yes
syslog = 0
log file = /var/log/samba/log.%m
max log size = 1000
dns proxy = No
usershare allow guests = Yes
panic action = /usr/share/samba/panic-action %d

wins support = yes

name resolve order = wins lmhosts host bcast


[TVShare]
path = /media/MEDIA2/TV
available = yes
valid users = benjamin
read only = no
browsable = yes
public = yes
writable = no

Where ls -dl /media/MEDIA2/TV/ reads

drwxrwxr-x 40 benjamin benjamin 4096 Sep  5 16:18 /media/MEDIA2/TV/

  • No Samba version, no logs, nothing about other versions of Windows... And have you tried to mount the share from the server machine itself? – sam_pan_mariusz Dec 20 '15 at 14:33
  • Added. Unable to try on other versions of windows - but thought the version may be of help – bak202 Dec 20 '15 at 15:09

To access the samba share, please pay attention to:

  1. You had to create a system user with the same username. In this case, please issue the following command: useradd -s /sbin/nologin benjamin
  2. If you are using a SELINUX-enabled system (eg: CentOS), try to temporarily disable it issuing setenforce 0

EDIT: as the problem persists, try the following:

  1. maybe your Windows host is prepending your username with the wrong domain name. From the Windows machine, try to login using localhost\benjamin as the username
  2. issue pdbedit -L and check if user benjamin is listed. If so, set a trivial password (you can change it later) using smbpasswd benjamin
  3. if user benjamin is not listed, try to recreate it issuing smbpasswd -a benjamin
  4. if it does not work, delete the passwd file (it is named passwd.tdb; for reference, in a CentOS 6.x system it is found under /var/lib/samba/private/). Then, recreate your user issuing smbpasswd -a benjamin
  5. if it still not working, try to use the root account issuing smbpasswd -a root and check if you can login using the root user. Note: this is only a try. After having done with it, you must delete root's entry issuing smbpasswd -x root
  • Thank you, the user I created is the same name/pass as an existing system user. I'll edit the question with more information – bak202 Dec 20 '15 at 15:04
  • I've edited my answer. Give it a try. – shodanshok Dec 20 '15 at 17:20
  • Tried 2-5 (it did exist in pdbedit) but had the same issue. After trying one, I get a new error in Windows: "...\TVShows is not accessible. You might not have permission to use this network resource..." – bak202 Dec 20 '15 at 18:10
  • Have you disabled SELINUX? – shodanshok Dec 20 '15 at 19:11
  • Thank you :) creating new user with password solved my problem :) – Soheyl Mar 16 at 20:03

On the Windows PC, Change HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel to 4

Network security: LAN Manager authentication level is usually set to Send LM & NTLM - use NTLMv2 session security if negotiated by Group policies for backup compatability with older clients.

Changing LmCompatibilityLevel to 4 sets it to Send NTLMv2 response only

  • Does this require a reboot on the client? – user643011 Jul 31 '18 at 17:08
