You would need to create an ldif and then add it with ldbmodify

An example:

dn: OU=AD Users,DC=samdom,DC=example,DC=com
objectClass: top
objectClass: organizationalunit
description: AD Users OU

dn: CN=front_office,OU=AD Users,DC=samdom,DC=example,DC=com
objectClass: top
objectClass: container
cn: front_office
description: front_office

dn: CN=managers,OU=AD Users,DC=samdom,DC=example,DC=com
objectClass: top
objectClass: container
cn: managers
description: managers

dn: CN=engineers,OU=AD Users,DC=samdom,DC=example,DC=com
objectClass: top
objectClass: container
cn: engineers
description: engineers

ldbmodify -H /var/lib/samba/private/sam.ldb -UAdministrator /root/ous.ldif

Not sure about this (I do not use GPO's) but if it is possible in
Windows it should be possible in Samba, whether the required tools are
available is another question ;-)
