Find DC IP

I can see we have a domain : (sevenkingdoms.local) and a sub domain about this: (north.sevenkingdoms.local), for end another domain: (essos.local)

I replaced <domain> in the command for the name of domain and subdomains we have

nslookup -type=srv _ldap._tcp.dc._msdcs.sevenkingdoms.local 192.168.56.10
Server:         192.168.56.10
Address:        192.168.56.10#53

_ldap._tcp.dc._msdcs.sevenkingdoms.local        service = 0 100 389 kingslanding.sevenkingdoms.local.

nslookup -type=srv _ldap._tcp.dc._msdcs.north.sevenkingdoms.local 192.168.56.10
Server:         192.168.56.10
Address:        192.168.56.10#53

Non-authoritative answer:
_ldap._tcp.dc._msdcs.north.sevenkingdoms.local  service = 0 100 389 winterfell.north.sevenkingdoms.local.

Authoritative answers can be found from:
winterfell.north.sevenkingdoms.local    internet address = 192.168.56.11

nslookup -type=srv _ldap._tcp.dc._msdcs.essos.local 192.168.56.10
Server:         192.168.56.10
Address:        192.168.56.10#53

Non-authoritative answer:
_ldap._tcp.dc._msdcs.essos.local        service = 0 100 389 meereen.essos.local.

Authoritative answers can be found from:
meereen.essos.local     internet address = 192.168.56.12

Setup /etc/hosts and Kerberos

All right, for we can use kerberos in linux we need configurate the /etc/hosts file and add the domains, subdomains and ips -->

sudo nano /etc/hosts
#GOAD
192.168.56.10   sevenkingdoms.local kingslanding.sevenkingdoms.local kingslanding
192.168.56.11   winterfell.north.sevenkingdoms.local north.sevenkingdoms.local winterfell
192.168.56.12   essos.local meereen.essos.local meereen
192.168.56.22   castelblack.north.sevenkingdoms.local castelblack
192.168.56.23   braavos.essos.local braavos

The order of implementing this is: ip -> domain name -> PcName+domain name -> PcName

Linux kerberos client

sudo apt install krb5-user
## Then
dpkg-reconfigure krb5-config

We answer the questions with :

• realm : essos.local

• servers : meereen.essos.local

  • admin_server : meereen.essos.local

The /etc/krb5.conf archive should be content this -->

// Some code[libdefaults]
  default_realm = essos.local
  kdc_timesync = 1
  ccache_type = 4
  forwardable = true
  proxiable = true
  fcc-mit-ticketflags = true
[realms]
  north.sevenkingdoms.local = {
      kdc = winterfell.north.sevenkingdoms.local
      admin_server = winterfell.north.sevenkingdoms.local
  }
  sevenkingdoms.local = {
      kdc = kingslanding.sevenkingdoms.local
      admin_server = kingslanding.sevenkingdoms.local
  }
  essos.local = {
      kdc = meereen.essos.local
      admin_server = meereen.essos.local
  }
...
