Sumário
Objetivo:
Ingressar no domínio do Windows Active Directory com o Samba Winbind.
Conceitos e Definicões:
Este procedimento abrange Servidores com Sistemas Operacionais baseados no Debian como Ubuntu, Mint ou outro derivado.
Fluxo de atividades:
1- Instale o Winbind e samba
root@smb:~# apt-get install -y install samba winbind libpam-winbind libnss-winbind krb5-config resolvconf
# specify Realm
+------------------+ Configuring Kerberos Authentication +------------------+
| When users attempt to use Kerberos and specify a principal or user name |
| without specifying what administrative Kerberos realm that principal |
| belongs to, the system appends the default realm. The default realm may |
| also be used as the realm of a Kerberos service running on the local |
| machine. Often, the default realm is the uppercase version of the local |
| DNS domain. |
| |
| Default Kerberos version 5 realm: |
| |
| SRV.WORLD________________________________________________________________ |
| |
| <Ok> |
| |
+---------------------------------------------------------------------------+
# specify the hostname of AD DS
+--------------+ Configuring Kerberos Authentication +---------------+
| Enter the hostnames of Kerberos servers in the SRV.WORLD |
| Kerberos realm separated by spaces. |
| |
| Kerberos servers for your realm: |
| |
| fd3s.srv.world____________________________________________________ |
| |
| <Ok> |
| |
+--------------------------------------------------------------------+
# specify the hostname of AD DS
+------------------+ Configuring Kerberos Authentication +------------------+
| Enter the hostname of the administrative (password changing) server for |
| the SRV.WORLD Kerberos realm. |
| |
| Administrative server for your Kerberos realm: |
| |
| fd3s.srv.world___________________________________________________________ |
| |
| <Ok> |
| |
+---------------------------------------------------------------------------+ 2- Configurar o Winbind
root@smb:~# vi /etc/samba/smb.conf
[global]
workgroup =
password server =
realm =
security = ads
idmap config * : range = 16777216-33554431
template shell = /bin/bash
template homedir = /home/%U
kerberos method = secrets only
winbind use default domain = yes
winbind offline logon = false
root@smb:~# vi /etc/nsswitch.conf
# line 7: add like follows
passwd: compat winbind
group: compat winbind
shadow: compat winbind
root@smb:~# vi /etc/pam.d/common-session
# add to the end if you need (auto create a home directory when initial login)
session optional pam_mkhomedir.so skel=/etc/skel umask=077
root@smb:~# systemctl restart smbd3- Ingresse o usuário na rede LDAP
root@smb:~# net ads join -U USUARIO_DE_REDE
Enter Administrator's password:
Using short domain name --
Joined 'SERVER' to dns domain 'anvisa.gov.br'
root@smb:~# systemctl restart winbind
# try to show domain users info
root@smb:~# wbinfo -u
administrator
guest
defaultaccount
serverworld
krbtgt4- Limitar o acesso ao servidor para apenas um ou vários grupos
root@smb:~# vim /etc/ssh/sshd_config
