Creating gitlab oauth token via authentication - oauth

Question

According to the docs, POSTing to /oauth/token with
{
"grant_type" : "password",
"username" : "user#example.com",
"password" : "sekret"
}
should respond with something like
{
"access_token": "1f0af717251950dbd4d73154fdf0a474a5c5119adad999683f5b450c460726aa",
"token_type": "bearer",
"expires_in": 7200
}
However, my gitlab server seems determined to reply to this request with 404:
$ http POST $GITLAB_API_HOST/api/v3/oauth/token grant_type=password username=$GITLAB_USERNAME password=$GITLAB_PASSWORD
HTTP/1.1 404 Not Found
Connection: keep-alive
Content-Length: 36
Content-Type: application/json; charset=utf-8
Date: Mon, 16 May 2016 03:24:16 GMT
Server: nginx
Status: 404 Not Found
X-Request-Id: a6dc1303-f1e8-43a2-8c47-227d5de533c7
X-Runtime: 0.003662
{
"error": "Not Found",
"status": "404"
}
I wasn't able to find an working example of this flow. Is there something I need to do to enable this endpoint on my gitlab (ee) installation?

Answer 1

Apparently the endpoint for these tokens is not under api/VERSION.
