Please tell me how can i get all this claim in my resource server

i have identity server that provide access token to the login user and api(multiple) that have bearer token authentication but in case of authorization I need to know how to authorize user by using user permissions and not only client scopes. the issue here is to load those permisions from authorization server independent from identity server because user might have to many permissions that can not be added into access token through IProfileService. I tried to add those permission into access token but it caused the token to be too large and request header has limitation of 8kb and 16kb in IIS server.
I was thinking of using IDistributedCache for sharing user permissions but I dont think it is a better solution.
I am trying to use client credentials grant for a back-end service using Keycloak as an identity broker for Azure AD. I also need to store access token from external IdP in Keycloak to retrieve group information from MS Graph API. I have this use case working for a confidential client using authorization code flow but I can't get it to work with client credentials grant.
I have created a "confidential" client in Keycloak with "Service Accounts Enabled" enabled. I have a also created an application in Azure AD with client credentials grant enabled and created a external Identity Provider in Keycloak.
I get the access token from Keycloak after authenticating using client_id and client_secret but when I try to retrieve external IdP access token from Keycloak endpoint, I get an error message that says, "User [GUID] is not associated with identity provider". I'd appreciate any suggestions or feedback.
Thank you Sventorben Posting your suggestions as answer to help other community members.
Though is grant on client credential from both side Azure AD and Keycloak it is not possible to store the access token from Azure AD in Keycloak and later retrieve it from Keycloak to make requests to Graph API.
The client credentials grant type is used by clients to obtain an access token. This is totally outside of the context of a user. Keycloak will not forward or redirect requests to AD in this case. Hence, there will never be an AD token. If you need client credentials grant issuing a token from AD, you will need to make the request to AD directly.
From the below document it seems Keyclock is broker it should never send the original access token which is receive from Azure AD to access the Graph API. Only you can read the token using enable StoredTokens Readable switch.

I need to get authenticated using OAuth2 client credentials as the grant type. The app would need to call the OAuth2 server with only the client id and client secret, get authenticated and receive an access token back, then the app can use the access token to obtain the application's data. There is no regular user involved and the data belongs to the app. This is the same concept as your application connects to the database with a user name and user password belong to the application. The user uses the application without any knowledge of backend database accesses.
There are so many OAuth2 servers that support "code" grant type such as Google, Facebook, Github, but I have not found anyone that supports client credentials. Google asks me to set a service account, it is not the same as client credentials. Does anyone know an OAuth2 server that I use to test my client credential grant code? Thanks.
Keycloak has support for client credentials as authentication for the token endpoint.

I have a SPA that logs users in with AAD and passes the JWT to a Web Api when making HTTP calls. I am trying to use this token that I capture in the Web Api to authenticate to Azure SQL using SqlConnection.AccessToken .
I am constantly getting "Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'".
I registered the app in AAD and am using the app id when requesting the token
This is not doable because a JWT can only have a single Audience. In order for this to work, an additional Audience Id would be required for Azure SQL.
I am a newbie to OAuth 2.0.
I have fairly read the OAuth 2.0 doc and I saw there are four types of methods for obtaining Authorization.
Types of obtaining authorization:
1.Implicit Grant
2.Resource Owner Password Credentials Grant
3.Client Credentials Grant
4.Authorization Code Grant
In my case, I have Client application, Resource owner, Resource server and Authorization server.
Resource server is a website where Resource owner registers with his/her credentials.
Client application is a third party website who registers into resource server and gets the Client application credentials for accessing it in future.
Authorization server checks the client credentials from client app and grants access token to the client app.
Let us consider, resource server as "www.serversite.com", authorization server as "www.authserver.com" and client application as "www.clientapp.com".
Flow:
Step 1: Also make an assumption that www.serversite.com as a payment gateway site and the client has to integrate "www.serversite.com" into "www.clientapp.com" for creating, executing and refunding payments.
Step 2: So the client "www.clientapp.com" creates an app in server "www.serversite.com" and gets API credentials.
Step 3: Using these API credentials, the client "www.clientapp.com" makes an access token request to the auth server "www.authserver.com".
Step 4: If the API credentials from client app are valid then the auth server grants an access token.
step 5: With this access token, client app request the resource server for further operations like creating payments as well as executing payments.
My questions:
I am using ASP.NET Web API for authorization server and using OWIN.OAuth for generating access token, refresh token, authorization and all the stuffs needed to authorize the client app.
But, in this link (OWIN OAuth 2.0 Authorization Server), I found that, the web api authorize the client app using "Resource Owner Password Credentials Grant" and the sample provided for implementing Owin.OAuth in web api is great, but I have lot of confusions roaming in my mind.
Which way of obtaining authorization is suitable for my process?
(Client Credentials flow or Resource Owner Password Credentials flow)
How to implement Client Credentials Grant type using ASP.NET Web
API(OWIN OAuth)?
Also provide some samples or links that may be helpful for me?
Thanks in advance.
Theres an example of how to get started on the asp.net website, specifically here:
http://www.asp.net/aspnet/overview/owin-and-katana/owin-oauth-20-authorization-server
I quote:
private Task GrantClientCredentails(OAuthGrantClientCredentialsContext context)
{
var identity = new ClaimsIdentity(new GenericIdentity(
context.ClientId, OAuthDefaults.AuthenticationType),
context.Scope.Select(x => new Claim("urn:oauth:scope", x))
);
context.Validated(identity);
return Task.FromResult(0);
}
Obviously you will need to go ahead and verify the actual client id / secret exist perhaps in a local database sometwhere before you go ahead and set the context to validated.
In terms of deciding which flow to use, you need to ask yourself, if the application is requesting access to your APIs on behalf of an actual user, then you need to use Resource Owner, however if the application itself needs access then Client Credentials is the way to go.
Generally speaking though, most implementations use Authorisation Code Flow, so if you can form a security stand point, get the users redirected to a page you host to take their credentials, opposed to sending them over the wire via Resource Owner Flow.
