Zwei DC mit Replikation einrichten

Situation

Existierender DC
Name: rumba
IP: 192.168.242.201
Ist DNS: Ja
Domain Informationen
DNS Domain Name: xinux.test
Kerberos realm: XINUX.TEST
Domain Admin: administrator
Admin-PW: password
Hinzuzufügender DC
Name: tango
IP: 192.168.242.200

Vorbereitungen

  • Beide Rechner sollten im selben Netz sein und sich pingen können
  • etc/hosts anpassen: Der Rechner muss sich unter seiner IP finden, bei localhost den Namen löschen
127.0.0.1   localhost   tango tango.xinux.test
192.168.242.200   tango tango.xinux.test
  • DNS anpassen: searchdomain eintragen und den existierenden DC als DNS angeben
nameserver 192.168.242.201
search xinux.test
  • DNS testen:
host -t A rumba.xinux.test
rumba.xinux.test has address 192.168.242.201

Kerberos

In der krb5.conf müssen folgende Einträge stehen: 

[libdefaults]
   dns_lookup_realm = false
   dns_lookup_kdc = true
   default_realm = XINUX.TEST

Testen ob man ein Kerberosticket bekommt 

root@tango:~# kinit administrator
Password for administrator@XINUX.TEST: 

root@tango:~# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: administrator@XINUX.TEST

Valid starting       Expires              Service principal
10.09.2015 11:08:57  10.09.2015 21:08:57  krbtgt/XINUX.TEST@XINUX.TEST

renew until 11.09.2015 11:08:44

Der Domain beitreten

  • ACHTUNG Für das Administrator-Passwort gelten die Standardrichtlinien von SAMBA4!
  • Weiterführende Infos: samba-tool domain join --help
root@tango:~# samba-tool domain join XINUX.TEST DC -Uadministrator --realm=XINUX.TEST --dns-backend=SAMBA_INTERNAL
