Invalid grant

[ghost]

I'm facing this issue every time I make POST request to /oauth2/access_token. This is my scenario:
I successfully integrated the provider and created a client from the admin console, without specifying any redirect uri because i'm working on localhost and I don't have any website yet. Now, if I try to get an access token at the specified url, I will get the token only if I make the request specifying username and password of an user which is admin. For any other user I will get "error: invalid grant". I tried every kind of solution but nothing seems to work.
I also noticed a strange thing: when I get the access token with the admin user, no grant and refresh token are created in the database...is this a normal behaviour?
I can't get this to work so how can I solve the problem?

Did you find a solution?

@ValerioRusso you should take a look at oauth2 specification. public token does not mean to have refresh tokens.

For me, I just had the password I was posting wrong.
