Cannot Authenticate with Authorization headers

[salami-art]

Hello,

I wasn't able, making a simple request with Postman, to get it authorized

Here's my request

POST /wp-json/wp/v2/posts/109441 HTTP/1.1
Host: xxxxxx
Authorization: OAuth oauth_consumer_key="xxxxxxx",oauth_token="xxxx",oauth_signature_method="HMAC-SHA1",oauth_timestamp="11234567",oauth_nonce="xxxxxx",oauth_version="1.0",oauth_signature="xxxxxxx"
Cache-Control: no-cache
Postman-Token: xxxxxx-xx0-40a8x8e8b-98fx1dex

"{"title":"New Post title"}"

Response:

headers:
...
Access-Control-Allow-Headers →Authorization
...

body:
{
"code": "rest_cannot_edit",
"message": "Sorry, you are not allowed to update this post.",
"data": {
"status": 401
}
}

Sending the same parameters as www-form results in a successful edit.

What am I missing?
