Invalid_grant error from Api Client #5611

muhittincelik created 8 years ago

Our web mvc project running and we can login.

But we can not authenticate from api client, we got invalid_grant , invalid_user_or_password error.

But username and password are correct, client id correct, address correct.

Do you have any idea ?

Hi @muhittincelik,

What is your ABP and AspNet Zero version ? I remember a similar problem in one of the v5.x versions.

MultiTenancyEnabled = true

And i have 2 warning in dependencies; I rebuild several times.

1- *.Core.Shared - System.ComponentModel.DataAnnotations (!) 2- *.Web.Mvc - npm.bootstrap4-datetimepicker.moment-timezone (not installed)

I think I have found the problem;

Assuming you have below settings in appsettings.json file;

"ApiName": "default-api",
"ApiSecret": "secret"

You need to change GetApiResources method of IdentityServerConfig like below;

public static IEnumerable<ApiResource> GetApiResources()
{
	return new List<ApiResource>
	{
		new ApiResource("default-api", "Default (all) API")
		{
			Description = "AllFunctionalityYouHaveInTheApplication",
			ApiSecrets= {new Secret("secret") }
		}
	};
}

You are probably passing wrong secret to server. Although secret must be hashed.

Try hashing the secret.

public static IEnumerable<ApiResource> GetApiResources()
{
	return new List<ApiResource>
	{
		new ApiResource("default-api", "Default (all) API")
		{
			Description = "AllFunctionalityYouHaveInTheApplication",
			ApiSecrets= {new Secret("secret").Sha256() }
		}
	};
}

It's under IdentityServer4.Models namespace that you are probably missing. You can get it from nuget.

@muhittincelik can you share server logs?

Its very hard to troubleshoot identityserver problems without logs.

You can implement how to via how to log identityserver if you haven't already.

You can use your 5.6.2 Core & JQuery package. I didnt add anything yet.

I am learning your framework and i will integrate our desktop software with your web application via api.
