Would it be possible to add a Samba (4.21) DC to an existing Microsoft 2019 domain? I have a vague memory of that the schemas are not compatible with the current MS version. Is that still correct? If so, is there any guide on how to upgrade the schema to make this possible? /Anders -- ------ -------------------- 8 ------------------ ------ "A *wise* man once told me - Any idiot can do backups, but it takes a genius to successfully restore" Anders ?stling +46 768 716 165 (Mobil)
