Estou trabalhando com o samba há algum tempo, mas me deparei com um problema. Eu tenho vários compartilhamentos e várias contas, mas as contas não têm acesso aos seus compartilhamentos definidos.
- Eu tenho um contêiner do Debian 9 no Proxmox;
- O usuário root pode acessar todos os compartilhamentos (adicionado ao samba
com smbpasswd -a);
- adicionei novos usuários usando useradd e smbpasswd -a;
Eu tenho os seguintes compartilhamentos:
[Backup]
browseable = yes
comment = Backup folder
create mode = 0775
guest ok = no
path = /mnt/backup
read only = no
valid users = root mark nextcloud
writable = yes
[Files]
browseable = yes
comment = General files
create mode = 0775
guest ok = no
path = /mnt/files
read only = no
valid users = root mark nextcloud
writable = yes
[Movies]
browseable = yes
comment = Movies and music folder
create mode = 0775
guest ok = no
path = /mnt/movies
read only = no
valid users = root mark nextcloud plex
writable = yes
[Pictures]
browseable = yes
comment = Pictures folder
create mode = 0775
guest ok = no
path = /mnt/pictures
read only = no
valid users = root mark nextcloud plex
writable = yes
[Git]
browseable = yes
comment = Git folder
create mode = 0775
guest ok = no
path = /mnt/git
read only = no
valid users = root git
writable = yes
Quando tento me conectar, por exemplo, com o compartilhamento de arquivos, os usuários root e mark podem acessá-lo, mas os usuários nextcloud e plex estão recebendo uma mensagem de acesso negado.
O testparm não me causa nenhum erro:

Completo /etc/samba/smb.conf:
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
#======================= Global Settings =======================

## Browsing/Identification ###
# Change this to the workgroup/NT-domain name your Samba server will part of

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no
# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
; wins server = w.x.y.z
# This will prevent nmbd to search for NetBIOS names through DNS.

#### Networking ####

# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0
# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes
#### Debugging/Accounting ####
# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m
# 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
# through syslog you should set the following parameter to something higher.

####### Authentication #######
# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.

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

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<[email protected]> for
# sending the correct chat script for the passwd program in Debian Sarge).

# classic domain controller', 'server role = backup domain controller'
# or 'domain logons' is set

# profile directory from the client point of view) The following

# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention

# RPC pipe. The example command creates a user account with a disabled Unix
# password; please adapt to your needs
