Samba Access Error session setup failed NT_STATUS_LOGON_FAILURE

Posted on

Using samba to access folders or files which has been shared depends on the samba file configuration that has already been configured. There are lots of parameters used in different values and purpose. Wrong configuration of samba service will affect the service itself so that it cannot serve its purpose to share files or folders correctly.

An error accessing samba shared which has already been defined is samba file configuration located in /etc/samba/smb.conf is shown below :

root@hostname:/var/log# smbclient -Umyguest -L //localhost/share
WARNING: The "syslog" option is deprecated
Enter myguest's password:
session setup failed: NT_STATUS_LOGON_FAILURE
root@hostname:/var/log# smbclient -Umyguest -L //localhost/share
WARNING: The "syslog" option is deprecated
Enter myguest's password:

root@hostname:/var/log# smbclient -Umyuser -L //localhost/share

This is the samba configuration file which is already defined :

;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log

####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the

########## Domains ###########

# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set

# It specifies the location of the user's
# profile directory from the client point of view) The following
# required a [profiles] share to be setup on the samba server (see
# below)
;   logon path = \\%N\profiles\%U
# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)
#   logon path = \\%N\%U\profile

# It specifies the location of a user's home directory (from the client

#   logon home = \\%N\%U

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention
;   logon script = logon.cmd

# This allows Unix users to be created on the domain controller via the SAMR
# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs
; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u

# This allows machine accounts to be created on the domain controller via the 
# SAMR RPC pipe.  
# The following assumes a "machines" group exists on the system
; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

# This allows Unix groups to be created on the domain controller via the SAMR

; add group script = /usr/sbin/addgroup --force-badname %g

############ Misc ############

# Using the following line enables you to customise your configuration

;   idmap uid = 10000-20000
;   idmap gid = 10000-20000
;   template shell = /bin/bash

# Setup usershare options to enable non-root users to share folders
# with the net usershare command.


# Maximum number of usershare. 0 (default) means that usershare is disabled.
;   usershare max shares = 100

# Allow users who've been granted usershare privileges to create
# public shares, not just authenticated ones
   usershare allow guests = yes

#======================= Share Definitions =======================

# Un-comment the following (and tweak the other settings below to suit)
# to enable the default home directory shares. This will share each
# user's home directory as \\server\username
;[homes]
;   comment = Home Directories
;   browseable = no

# By default, the home directories are exported read-only. Change the
# next parameter to 'no' if you want to be able to write to them.
;   read only = yes

# File creation mask is set to 0700 for security reasons. If you want to
# create files with group=rw permissions, set next parameter to 0775.
;   create mask = 0700

# Directory creation mask is set to 0700 for security reasons. If you want to
# create dirs. with group=rw permissions, set next parameter to 0775.
;   directory mask = 0700

# By default, \\server\username shares can be connected to by anyone
# with access to the samba server.
# Un-comment the following parameter to make sure that only "username"
# can connect to \\server\username
# This might need tweaking when using external authentication schemes
;   valid users = %S

# Un-comment the following and create the netlogon directory for Domain Logons
# (you need to configure Samba to act as a domain controller too.)
;[netlogon]
;   comment = Network Logon Service
;   path = /home/samba/netlogon
;   guest ok = yes
;   read only = yes

# Un-comment the following and create the profiles directory to store
# users profiles (see the "logon path" option above)
# (you need to configure Samba to act as a domain controller too.)
# The path below should be writable by all users so that their
# profile directory may be created the first time they log on
;[profiles]

;   path = /home/samba/profiles
;   guest ok = no
;   browseable = no
;   create mask = 0600
;   directory mask = 0700

So, overall the definition which is used in samba file configuration is shown as follows :

[global]

workgroup = WORKGROUP
server string = %h server (Samba, Ubuntu)
dns proxy = no
log file = /var/log/samba/log.%m
max log file = 1000
syslog = 0
panic action = /usr/share/samba/panic-action %d
server role = standalone server
passdb backend = tdbsam
obey pam restrictions = yes
unix password sync = yes
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully*.
pam password change = yes
map to guest = bad user
usershare allow guests = yes

The above configuration doesn’t include folder or files sharing definition, more over, after googling here and there, of the solution given is done by adding the following entry in samba configuration file located in /etc/samba/smb.conf :

To solve the above problem arises, there is a need to change samba file configuration which is located in /etc/samba/smb.conf by adding one line as shown follow :

bind_interfaces_only = no

By default, there is a commented entry of bind_interfaces_only = yes which might be the value of the default parameter although it is not being defined. It can be shown as follows :

After changing samba configuration file by inserting parameter above with the value defined. Start samba’s service by executing the following command :

systemctl restart smbd.service

Below is the trial of access after editing samba configuration and restarting the service :

root@hostname:/var/log# smbclient -Umyguest -L //localhost/share
