Windows 10 NÃO está pedindo senha para compartilhamentos samba do Ubuntu

Question

Recentemente, fiz uma instalação limpa do 16.04.3LTS em um novo laptop. Estou tentando compartilhar arquivos do meu laptop ubuntu na minha rede doméstica. Eu quero que apenas usuários específicos possam acessar os compartilhamentos de samba e exigir autenticação de senha. Atualmente, o Windows 10 tem acesso total sem necessidade de senha ???? O que há de errado com minha configuração do samba?

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field
    server string = %h server (Samba, Ubuntu)

# 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.
    dns proxy = no

#### Networking ####

# The specific set of interfaces / networks to bind to
# 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

####### 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.
    server role = standalone server

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.  
;   passdb backend = tdbsam

    obey pam restrictions = yes

# 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.
    unix password sync = yes

# 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).
    passwd program = /usr/bin/passwd %u
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
    pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

Antes que alguém diga que deve ser um problema com as credenciais do Windows 10 ... Eu já tentei remover todas as credenciais da rede (na verdade não havia nenhuma) e ainda tenho o mesmo problema.

    

Answer 1

Isso geralmente acontece quando o usuário do samba corresponde ao usuário atualmente conectado. Então, se você criar um compartilhamento de samba para CHAD e no PC remoto, seu nome de usuário também é CHAD, ele não pedirá uma senha e deixará você entrar. (Acredito que as senhas também têm que corresponder, elas se transformam em um login automático) por assim dizer).

Agora, se você quiser que o compartilhamento exija uma senha, não importa o quê, o que você poderia tentar é adicionar a linha security = user ao seu smb.conf e ele deve exigir uma senha agora. / p>

Isso tudo está assumindo que ambos os nomes de usuários no cliente e no servidor são os mesmos.
