3. initial entries base dn

   neo@master:~$ cat base-dn.ldif
   					
   dn: dc=example,dc=org
   objectclass: dcObject
   objectclass: organization
   o:example.org
   dc: example
   description:Top level of directory
   
   dn: cn=Manager,dc=example,dc=org
   objectclass: organizationalRole
   cn: Manager
   
   dn: cn=admin,dc=example,dc=org
   objectclass: organizationalRole
   cn: admin
   
   dn: cn=root,dc=example,dc=org
   objectclass: organizationalRole
   cn: root

   neo@master:~$ ldapadd -x -D "cn=admin,dc=example,dc=org" -W -f base-dn.ldif
   Enter LDAP Password:
   adding new entry "dc=example,dc=org"
   
   adding new entry "cn=Manager,dc=example,dc=org"
   
   adding new entry "cn=admin,dc=example,dc=org"
   
   adding new entry "cn=root,dc=example,dc=org"					
   					

   check

   					
   neo@master:~$ ldapsearch -x -b 'dc=example,dc=org' '(objectclass=*)'
   # extended LDIF
   #
   # LDAPv3
   # base <dc=example,dc=org> with scope subtree
   # filter: (objectclass=*)
   # requesting: ALL

   neo@master:~$ sudo slapcat -l master.ldif
