Winbind Centos неправильный UID / GID

Вот сценарий:

У меня две машины:

Ubuntu, запускающий ldap для аутентификации пользователей

CentOs, использует winbind для аутентификации пользователей

для монтирования хомедиров я использую общие ресурсы fstab и nfs.

Проблема вот в чем:

в Ubuntu в getent passwd пользователь выглядит так:

john:x:3000052:1901:John Doe:/home/john:/bin/bash

но в CentOs тот же пользователь использует это в getent passwd:

john:*:16777228:16777218:John Doe:/home/john:/bin/bash

как вы можете видеть, UID и GID не совпадают, что разрешает разрешения, которые запрещены, когда пользователь пытается получить доступ к этому homefoler в CentOS. Я хочу, чтобы CentOS имел те же UID и GID, что и Ubuntu, для пользователей AD.

Мне удалось узнать кое-что об idmap в smb.conf, но у меня он не работает.

[global]
idmap workgroup = MOSEK
idmap config MOSEK:backend  = rid
idmap config MOSEK:base_rid = 0
idmap config MOSEK:range    = 3000040 - 4999999

#--authconfig--start-line--

# DO NOT EDIT THIS SECTION (delimited by --start-line--/--end-line--)
# Any modification may be deleted or altered by authconfig in future

workgroup = MOSEK
...autogenerated stuff
#--authconfig--end-line--

Но это не работает.

Надеюсь, я понимаю, что пытаюсь сделать

хорошо, вот что сгенерировал для меня authconfig. Учитывая ваш ответ, я думаю, это может быть актуально.

EDIT2: когда я попытался предоставить sssd.conf правильные разрешения, у меня появилась новая ошибка:

РЕДАКТИРОВАТЬ3:

хорошо, я последовал за вашим руководством, и вот что я сделал от начала до конца:

[root@centosy sssd]# authconfig --update --disableldap --ldapbasedn="dc=mosek,dc=zentyal" --ldapserver="ldap://172.16.0.5" --enablerfc2307bis --disablekrb5 --enablekrb5kdcdns --krb5realm=mosek.zentyal --enablesssd --enablesssdauth --enablemkhomedir --enablepamaccess --enablelocauthorize --smbrealm=mosek.zentyal --smbservers=nyborg.mosek.zentyal --smbworkgroup=MOSEK --smbsecurity=ads
getsebool:  SELinux is disabled

[root@centosy sssd]# net ads join createupn=host/`hostname -f`@MOSEK.ZENTYAL -U tomas
Ignoring unknown parameter "idmap workgroup"
Ignoring unknown parameter "idmap workgroup"
Enter tomas's password:
Using short domain name -- MOSEK
Joined 'CENTOSY' to dns domain 'mosek.zentyal'

и вот мой sssd.conf:

[sssd]
 config_file_version = 2
 domains = mosek.zentyal
 services = nss, pam
 debug_level = 0

[nss]

[pam]

[domain/mosek.zentyal]
 debug_level = 5
 cache_credentials = false
 enumerate = false
 id_provider = ldap
 auth_provider = krb5
 chpass_provider = krb5
 access_provider = ldap

 ldap_sasl_mech = GSSAPI
 ldap_sasl_authid = host/nyborg.mosek.zentyal@MOSEK.ZENTYAL
 ldap_sasl_canonicalize = false

 ldap_user_search_base = ou=Users,dc=mosek,dc=zentyal
 ldap_user_object_class = user
 ldap_user_home_directory = unixHomeDirectory
 ldap_user_name = sAMAccountName
 ldap_user_shell = loginShell

 ldap_group_name = msSFU30Name
 ldap_group_object_class = group
 ldap_group_search_base = ou=Groups,dc=mosek,dc=zentyal

 ldap_access_order = expire
 ldap_account_expire_policy = ad
 ldap_force_upper_case_realm = true
 ldap_disable_referrals = true
 ldap_id_mapping = false
 ldap_schema = rfc2307bis

 krb5_realm = MOSEK.ZENTYAL
 krb5_canonicalize = false
 krb5_server = mosek.zentyal

так что теперь я перезапускаю sssd:

[root@centosy sssd]# service sssd restart
Redirecting to /bin/systemctl restart  sssd.service
