I'm building an API where i want to use password as grant_type. I set it up using FOSOAuthServer Bundle.
I tried to get token without first providing the client_secret and it says that invalid client.
Then I included client_secret, and now its working. I think OAuth2 states that password grant_type should not include client_secret in the request.
Note:
I used bot GET/POST method, but still with no luck.
Thanks!
