Does anyone know how to get the app access token to a One-Drive API app?
I've tried combining {appId}|{appSecret} as the access_token param and as the Authorization header but it doesn't seem to work.
Thanks,
The OneDrive API docs have a good section on getting auth tokens with OAuth. In a nutshell, there are two services involved -- the OneDrive API service and the authentication service. The OneDrive API only accepts OAuth tokens that were issued by the authentication service. The authentication service is what you talk to first to get an auth token.
Depending on your app, you can either use the token flow or the code flow to get an auth token. In the 'token' flow, you navigate the user's browser to the authentication endpoint with your appId. The user may need to log in, consent, etc., and then the authentication endpoint redirects back to your site with an auth token you can use. The 'code' flow is similar to the 'token' flow, except it redirects back with an authentication code that your client app can use (along with its client secret) to obtain an auth token and a refresh token. Once you have a refresh token, you can use that to obtain future auth tokens without the user's involvement (as long as they granted the wl.offline_access scope).

We are trying to use auth0 for spring-boot application authentication.
Created Regular Web Application and Machine to Machine Applications in auth0.com and added users under User Management.
Intention is to have a login API to authenticate users and get the access-token after the successful authentication. Use access token (as bearer token) to access other APIs of the spring-boot application.
We provided proper login and callback urls under the Machine To Machine application configuration in auth0.com.
While generating bearer token, apart from client_id, client_secret we have provided grant_type (as client_credentials), audience as https://<>/api/v2 and scope with (openid profile my_scope email roles).
We are getting 401 error while accessing the other APIs using bearer token generated using client_id, client_secret, grant_type and audience.
Wherein, we are getting 403 error while accessing the other APIs using bearer token generated using client_id, client_secret, grant_type, audience and scope.
403 error stack is as below
Client is not authorized to access <<application-domain-in-auth0>>/api/v2/. You need to create a client-grant associated to this API.
We referred to the udemy session (https://www.udemy.com/course/build-secure-apis-with-auth0-and-postman/learn/lecture/12716335#overview)
Any inputs on the overall approach and where we are going wrong.
Thanks

not sure if it can help, but found this more relevant to the problem statement.
https://community.auth0.com/t/how-to-generate-a-management-api-token-automatically/6376
There are a few things you need to do/check:
Create a non-interactive client in Auth0, which will be used to represent your service.
Authorize the non-interactive client to call the Auth0 Management API:
Dashboard > APIs > Auth0 Management API > Non Interactive Clients > Authorize your client
Ensure that the parameters used in the call to /oauth/token are for your non interactive client:
{
grant_type: 'client_credentials',
client_id: 'NON-INTERACTIVE-CLIENT-ID',
client_secret: 'NON-INTERACTIVE-CLIENT-SECRET',
audience: 'https://yourdomain.auth0.com/api/v2/" }
Make sure the access token you receive is passed in the Authorization header for every request made to the Management API. Authorization: Bearer <access_token>
I have an api written in GO that, at the moment, serves an authorization token based on a username and password. (Without MSAL)
I am trying to implement MSAL logins with Microsoft accounts. I have setup my angular frontend to log a user in to an Azure AD app registration. Would it be possible to authenticate that they have successfully logged in to the Azure AD, and serve them one of my tokens (unrelated to msal) from my GO API?
The username that they use to login with MSAL also exists in my backend, the flow would be something like this;
User logs in with MSAL -> my frontend makes a request to golang backend with username -> golang verifies that this username has logged in with MSAL -> backend serves a token for this user
It appears golang integration with MSAL is limited, so not sure how possible this is.
Thanks.
What you can do is acquire an access token for your API in the front-end from Azure AD. For this you will either register the API in Azure AD or use the same app registration. Either way, you should add a scope in the Expose an API page in the registration. Your front-end can then use that scope's id to get the needed token.
Your API can then have an endpoint that validates the access token, and issues the local token. The access token will contain the user's username for example, if you want to map to that. A more robust way would be to map to the user's object id (also in the token) since it is immutable, unlike the user email.
For token validation, you should be able to use a generic JWT validation library. Also remember to check for that scope in the token that you defined to properly authorize the request.
I have a Spring Boot Rest Api with JWT integration. Currently from Postman, I make a POST request to authenticate endpoint, including username and password, and obtain an access token.
But can Azure AD be used along with JWT, instead of hardcoded user details ?
When you obtain token with username and password, that bases on Resource Owner Password Credentials flow. This flow requires a very high degree of trust in the application, and carries risks which are not present in other flows.
I'm not sure what you mean about Azure AD with JWT.
If you would like to obtain access token with a signed-in user(not hardcoded user details), auth code flow is better for you. You could also request an access token in Postman.
POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
client_id=xxx
&scope=https://graph.microsoft.com/mail.read
&code=<authorization_code from "/authorize" endpoint>
&redirect_uri=http%3A%2F%2Flocalhost%2Fmyapp%2F
&grant_type=authorization_code
If you would like to obtain access token without users, you could use client credentials flow. In the client credentials flow, permissions are granted directly to the application itself by an administrator, so you must use application permissions.
POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
client_id=xxx
&scope=https://graph.microsoft.com/.default
&client_secret=xxxx
&grant_type=client_credentials
I'm currently using Keycloak 9.0.0. When authenticating using the code flow and exchanging this code, I'm receiving an id token without the at_hash claim.
How do I configure Keycloak to include an at_hash claim in the id token?
Background:
I'm using a "classic" server side rendered (SSR) program, a confidential client.
I'm sending requests to my local http api. But I also have an Angular client. The SSR is a Go programm using github.com/coreos/go-oidc.
Rendered pages that require authentication redirect the visitor to keycloak and back via the redirect_uri.
Since the visitor is logged in its id token is present in the session and I also pass the access token. However the id token has no at_hash claim and thus access token validation fails.
I also have a mobile web version of this site, in Angular and it sends a bearer access token once logged in. This app uses the code flow + pcke.
Both should be able to send authenticated requests, but since I'm using pretty much the only oidc client library for Go available, it requires an at_hash claim being present in the id token to be able to verify access tokens. The package currently has no support for the introspection endpoint.
Both id token and access token are returned from the IDP. But neither has an at_hash claim.
According to OIDC at_hash is mandatory only when access token is issued.
Make sure you are using response_type=id_token token and not response_type=id_token.
We would like to have REST APIs with OAuth2 using our own user table for Authentication. Also, we need to allow Social Login. Below is the flow for social login,
Our OAuth
Client makes auth and access token URL for our servers to receive
the access token
Client sends access_token for further calls in the header as bearer
token
Social Login
Client makes auth and access token URL to Social Login server(For
ex,https://accounts.google.com/) to receive an access token
The client sends access_token for further calls in the header.
We have implemented our OAuth with Spring and working perfectly. We have questions on social login,
How to identify our own Oauth access token and social login access
token. We may have many social logins and we should able to identify corresponding social login.
How to validate and integrate with Spring Boot?
If the access tokens are just random strings, you probably cannot tell the issuer of the provided token and you cannot validate it.
I would suggest you to extend your OAuth2 server to accept third party providers (Google, Facebook ...) for authentication. This way would support both local and social users, but in your application, you would always deal with your own tokens. It would make the application security much easier (which usually means safer) and you could also configure your own scopes for access tokens. There are also ready to use solutions for it - e.g. Keycloak.
