Моя главная цель - настроить Samba-сервер, к которому пользователи могут подключаться, используя свои учетные данные Active-Directory. Кроме того, локальные пользователи Linux на Samba-Server должны иметь возможность аутентифицироваться.
Сначала я попытался настроить Samba-Server для аутентификации пользователей в Active Directory, но не мог понять, как это сделать.
Samba-Server версии 4.2.10 работает на CentOS 7. Моя Samba-конфигурация выглядит так:
/etc/samba/smb.conf
[global] workgroup = AD netbios name = clients-hostname max log size = 50 log level = 3 log file = /var/log/samba3/log.%m map untrusted to domain = Yes winbind enum users = yes winbind enum groups = yes winbind cache time = 10 winbind nss info = rfc2307 winbind trusted domains only = no winbind use default domain = yes winbind refresh tickets = yes os level = 20 winbind enum groups = yes realm = AD.COMPANY.CPOM security = ads auth methods = winbind passdb backend = tdbsam client use spnego = yes client ntlmv2 auth = yes [aShare] available = yes path = /aShare browseable = yes writeable = yes #read only = no #inherit acls = yes #inherit permissions = yes create mask = 0777 directory mask = 0777 valid users = @"domain users@AD",localUser
Конфигурация Kerberos выглядит так:
/etc/krb5.conf
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
[libdefaults]
dns_lookup_realm = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
rdns = false
default_realm = AD.COMPANY.COM
default_ccache_name = KEYRING:persistent:%{uid}
[realms]
AD.COMPANY.COM = {
kdc = DC.AD.COMPANY.COM
kpasswd_server = DC.AD.COMPANY.COM
admin_server = DC.AD.COMPANY.COM
default_domain = AD.COMPANY.COM
}
[domain_realm]
.ad.company.com = AD.COMPANY.COM
ad.company.com = IN.ITM-CONSULTING.DE
Самба-сервер существует в Active-Directory, и я получил kerberos-ticket. wbinfo -u отображает всех пользователей в Active Directory. Я заметил, что раньше он отображал пользователей с префиксом AD \, теперь у них больше нет этого префикса.
Основная проблема в том, что я не могу подключиться к общим ресурсам с пользователем активного каталога:
$ smbclient -L //10.0.0.2 -U aduser -W AD
Enter aduser's password:
session setup failed: NT_STATUS_LOGON_FAILURE
Журналы показывают мне это: /var/log/samba3/log.10.0.0.2 [<- IP-адрес локальных машин]

Как я могу позволить пользователям входить в samba со своими учетными данными из Active Directory?
