As for your question in general the passport is not a strict requirement to get the permission for he Ausbildung from the Foreign Office, however one of the requirements are your German language skills, you have to proof(as far as possible) your Identity, have no been in conflict with the law before, the Ausbildung have to at a company, your country of origin should not be on the list of "Sichere Herkunftsländer". If the Ausländerbehörde rejects your application ask for a written reasoning of the rejection, as in such a case you can appeal the rejection.
I hope I could assist you with the answer, if you have open questions please do not hesitate to use the platform.
