Using v2 token endpoint still giving v1 token: Azure Active Directory - oauth-2.0

I created a new app registration and set scopes for Application.Read.All and User.Read.All. I exposed one custom scope as access_as_user. Using v2 token endpoint still giving v1 tokens that is the main issue now.
v1 token endpoint: https://login.microsoftonline.com/tenantid/oauth2/token
v2 token endpoint: https://login.microsoftonline.com/tenantid/oauth2/v2.0/token
Both endpoints giving tokens with same version i.e, version 1.0 Why so?
If I registered multitenant applications then it is giving tokens with version 2.0 with both endpoints.
My requirement is to get v2.0 tokens for single tenant applications. Any way to achieve this?

I tried to reproduce the same in my environment and got below results:
I registered one single tenant application and granted API permissions like below:
When I checked the Manifest of this application, accepted token version is null as below:
I generated the token for custom scope using v2.0 token endpoint via Postman like below:
POST https://login.microsoftonline.com/<tenantID>/oauth2/v2.0/token
grant_type:client_credentials
client_id:<appID>
client_secret:<secret>
scope: api://xxxxxxxxxxxxxxxxxxx/.default
Response:
When I decoded the above token in jwt.ms, token version is 1.0 as below:
To get v2.0 token, you need to change your application's Manifest like below:
When I generated the token again and decoded it, I got the token version as 2.0 as below:
In your case, change the accessTokenAcceptedVersion to 2 in your Manifest's file and generate the token again.

How to connect custom API using own OAuth2 in Microsoft Power Automate?

I've been trying to connect Microsoft Power Automate to my API. My API has a OAuth2 Code Flow.
According to Power Automate, the connector can make a connection to my API. and execute a test. But the problem is that Microsoft sends a Bearer token that was generated by them, and not the one that I gave to them via OAuth2, resuting on my API giving a 401 Error (Invalid Token) as expected.
In the Power Automate Custom Connector page, in the security tab I have the following:
Authentication type
OAuth2.0
OAuth2.0 Settings
Identity Provider: Generic OAuth2
Client ID: SomeValue
ClientSecrect: SomeValue
Authorization URL: mydomain.com/auth/authorize
Token URL: mydomain.com/auth/token
Refresh URL mydomain.com/auth/token
Redirect URL: microsoft-flow.com/redirect (Not the real one)
When Microsoft makes a POST request to mydomain.com/auth/token, I return the following body:
{
access_token: "non JWT token", // simillar to a hash
refresh_token: "non JWT token",
expires_in: 3600
}
The request above is final request that microsoft before accepting as a valid connection. The token that microsoft sends me is a JWT one, not the one I provided.
I've seen some guys using Azure AD authentication within the APP, but I was trying to implement something simillar to other platoforms(e.g Github, Spotify, e.t.c)
So my question is it possible to connect Power Automate to a custom API with using OAuth2? If yes, how to do it?
It's possible.
In addition to the OAuth2.0 Settings you listed, there is another important property Scope which you have missed.
Since your API is protected in Azure AD, so I assume that you have created an Azure AD app for your API and exposed scopes.
After that, you can get the application ID URI (api://{clientId}) for your API.
You should put this value into the "Scope" in Power Automate, like this:
Then this access token will be considered valid by your API.
I've done two steps to fix this problem.
Step 1
Previously my API returned the body with access_token, refresh_token and expires_in, but then I added scope and token_type. Example:
{
access_token: "2346ad27d7568ba9896f1b7da6b5991251debdf2",
refresh_token: "4468e5deabf5e6d0740cd1a77df56f67093ec943",
expires_in: 3600,
scope: "none",
token_type: "Bearer"
}
Step 2
Delete the custom connector and create a new one with the same parameters. When I got to the "Test" section, Power automate finally could make the GET request successfully.
In my case, even if the the API was updated, Power automate was still using its faulty token, so I had to delete that custom connector and create new one.
Conclusion
By updating the API and deleting the old custom connector, I was able to get the connector working.

How to simply get a bearer token to send requests to Azure DevOps API?

I need to create an organizational feed to host nuget packages shared among projects on our Azure DevOps environment.
After several unsuccesful attempts and research, I discovered that the only way to create an organizational feed is, by design from Microsoft mouth, the Azure DevOps API.
Source for the claim : This question on VS dev community
and The MS docs on project-scoped feeds
Basically, I just need to be able to perform a POST here :
https://feeds.dev.azure.com/{organization}/_apis/packaging/feeds?api-version=5.1-preview.1
with the body :
{
"name": "{myfeedname}",
"hideDeletedPackageVersions": true,
"upstreamEnabled": true
}
And of course, a Bearer token to authenticate myself. That's the point where I'm confused.
What is the simplest way to obtain one ? I'm logged in through my company Microsoft AD account on my computer browser on Azure DevOps. I don't see any Bearer token that I can "steal" to use in PostMan in my browser dev tools.
The API docs described some relevant info, but I'm confused on how to use it in Postman :
Security oauth2
Type: oauth2
Flow: accessCode
Authorization URL: https://app.vssps.visualstudio.com/oauth2/authorize&response_type=Assertion
Token URL: https://app.vssps.visualstudio.com/oauth2/token?client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer&grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer
Scopes Name Description
vso.packaging_write Grants the ability to
create and read feeds and packages.
Here is the interface in Postman for OAuth2:
Ican see how the info in the docs relates to the fields 1 - 2 - 3 - 4, but then, what callback url should I use ? What credentials ? my Microsoft email + password from AD ?
I tried this, and all I seem to get is this from Postman :
{"$id":"1","innerException":null,"message":"A potentially dangerous Request.Path value was detected from the client (&).","typeName":"System.Web.HttpException, System.Web","typeKey":"HttpException","errorCode":0,"eventId":0}
TLDR
How do I properly proceed to get a token with Postman, or other tool to manually execute my one-time request to Azure DevOps REST API ?
notes :
Following info here : Unable to get Authorization code for Devops using Postman oAuth2.0
, leading here : https://github.com/Microsoft/azure-devops-auth-samples/tree/master/OAuthWebSample , I understand that I have to register and run a whole web application. Am I understanding this correctly ? I there a simpler way ?
I understand that I have to register and run a whole web application. Am I understanding this correctly ? I there a simpler way ?
Yes, you are right. You have to register whole web application.
As the interface in Postman for OAuth2, we need provide the CallbackUrl, ClientID, ClientSecret and so on. Then, we check the document Requesting an OAuth 2.0 token, we could to know the Callback URL is:
The client application callback URL redirected to after auth, and that
should be registered with the API provider.
So, we have to register an OAuth client app in Azure DevOps (https://app.vsaex.visualstudio.com/app/register), then we could get the following information, like:
You could check the document Authorize access to VSTS REST APIs with OAuth 2.0 for some more details.
AFAIK, there is currently no simpler way to get a bearer token to send requests to the Azure DevOps API.
Hope this helps.

Get Azure AD directory users in a Rails app

I have a Rails 6 application and I want to use Azure Active Directory as an authentication system (with open id connect, saml2 and ldap).
The authentication is done.
Now I am trying to display user information like names or email addresses. I also want to be able to export all users of a directory.
I have tried to set a configuration up like so:
In my Rails app, in the admin panel, an admin can configure Azure AD for my application
in the config, the admin copies and pastes the configuration link provided by Azure AD (a JSON response)
Then, copies and pastes the app client_id
Then, the tenant_id (directory id)
Here is a piece of code that I expected to work:
def update_oidc
identity_provider = IdentityProvider.find_by(provider_type: 'open_id_connect', id: params[:id])
client_id = params[:client_id].strip
metadata_url = params[:metadata_url].strip
tenant_id = params[:tenant_id].strip
metadata = HTTParty.get(metadata_url).parsed_response
identity_provider.update(config: {
metadata: metadata,
metadata_url: metadata_url,
client_id: client_id,
tenant_id: tenant_id,
})
if tenant_id
directory_access_url = "https://graph.windows.net/#{tenant_id}/users?api-version=1.6"
result = HTTParty.get(directory_access_url).parsed_response
identity_provider.directories.find_or_create_by(tenant_id: tenant_id).update(
business_phones: result["business_phones"],
display_name: result["display_name"],
given_name: result["given_name"],
job_title: result["job_title"],
email: result["user_principal_name"],
mobile_phone: result["mobile_phone"],
office_location: result["office_location"],
surname: result["surname"]
)
end
redirect_to identity_provider
end
As the tenant_id is the directory id, i thought that we might be able to access user info this way (and following the Microsoft Docs). The thing is, it doesn't work because even though I'm connected to my Azure AD directory in my app, when I run result = HTTParty.get(directory_access_url).parsed_response, i have an authentication error telling me the token has expired or that i need to be connected.
I don't want to use PowerShell or anything like this. I want to be able to access directories data through my app.
Can someone tell me what i'm doing wrong or come up with an idea ?
Thanks
Just according to your code, I think you want to get the collection of users via the Azure AD Graph REST API Get users using jnunemaker/httparty library.
However, it seems to be missing the required header Authorization with its value like Bearer eyJ0eX ... FWSXfwtQ as the section Authentication and authorization of the offical document Operations overview | Graph API concepts said. Meanwhile, you have done the authentication with OpenID Connect, but Azure AD Graph API requires the access token as Authorization value from OAuth2 as the content below said.
The Graph API performs authorization based on OAuth 2.0 permission scopes present in the token. For more information about the permission scopes that the Graph API exposes, see Graph API Permission Scopes.
In order for your app to authenticate with Azure AD and call the Graph API, you must add it to your tenant and configure it to require permissions (OAuth 2.0 permission scopes) for Windows Azure Active Directory. For information about adding and configuring an app, see Integrating Applications with Azure Active Directory.
Azure AD uses the OAuth 2.0 authentication protocol. You can learn more about OAuth 2.0 in Azure AD, including supported flows and access tokens in OAuth 2.0 in Azure AD.
So I'm afraid you have to get the access token manually via OAuth2 for Azure AD again for using Graph API, or just simply refer to the sample code samples/authorization_code_example/web_app.rb using the adal library of GitHub repo AzureAD/azure-activedirectory-library-for-ruby for Ruby.

How do I authenticate against the Dynamics 365 Data Export Service API?

I've set up something called the Data Export Service for Dynamics 365 so that it replicates into an Azure SQL database. This is working as expected.
I'm trying to find a way to be proactively notified if this service encounters any errors. There does not appear to be a native way to do this through the setup in CRM itself, but they do provide an API. The Swagger page outlining all methods can be found here.
I'm trying to call the GetProfilesByOrganizationId method using Postman:
https://discovery.crmreplication.azure.net/crm/exporter/profiles?organizationId=4ef7XXXX-XXXX-XXXX-XXXX-XXXXXX8a98f&status=true
I'm having issues with authentication and always receive the following error:
"Message": "Received unauthenticated requestRequest Url https://discovery.crmreplication.azure.net/crm/exporter/profiles?organizationId=4ef7XXXX-XXXX-XXXX-XXXX-XXXXXX8a98f&status=true"
I have registered an application in Azure that has permission to access Dynamics 365 on behalf of the authenticated user which in this case is me, the administrator.
I have set the Type to OAuth 2.0 on the Authorization tab of Postman. I have requested an Access Token using the Grant Type of Authorization Code against the above application successfully. This has added a header to the request:
Key: Authorization
Value: Bearer BIGLONGACCESSTOKEN
Despite this header being present I still get the error mentioned above.
The API documentation implies the authentication is OAuth2 Implicit Grant Flow (click on any red exclamation mark in the documentation) but I can't get this to work in Postman. When I try to request a token with this method I get the error:
unsupported_response_type
... in the Postman console.
Any ideas how to authenticate (with Implicit Grant?) against this API in Postman?
(I'd accept C# examples if they're more appropriate, but I'd be surprised if Postman can't show me what I need)
It looks like the code sample shown by Microsoft can work if updated with newer methods and with some extra configuration in Azure that's not documented.
Azure configuration
By installing the Data Export service (and assuming it's all working) you'll have a new Enterprise Application listed in Azure AD as Crm Exporter.
To take advantage of this application and authenticate with the Data Export API you must configure an app of your own.
Go to the App registrations tab in Azure AD and add a new application registration.
Give it a name and set the Application type to Native. The redirect URI doesn't typically matter as long as it's valid.
Click the Manifest button to edit the manifest, change the property oauth2AllowImplicitFlow to true and save the changes.
The only other important configuration is Required permissions which should be set as below:
Windows Azure Active Directory
Delegated permissions
Sign in and read user profile
Data Export Service for Microsoft Dynamics 365 (Crm Exporter)
Delegated permissions
Have access to Data Export Service for Microsoft Dynamics 365 API
You will then need to click Grant Permissions.
C# changes
The updated method looks like this:
using Microsoft.IdentityModel.Clients.ActiveDirectory;
string clientId = "11cfXXXX-XXXX-XXXX-XXXX-XXXXXXXXd020";
string user = "my.username#domain.com";
string password = "PASSWORD";
var authParam= await AuthenticationParameters.CreateFromResourceUrlAsync(
new Uri("https://discovery.crmreplication.azure.net/crm/exporter/aad/challenge")
);
var context = new AuthenticationContext(authParam.Authority, false);
var credentials = new UserPasswordCredential(user, password);
var token = await context.AcquireTokenAsync(authParam.Resource, clientId, credentials).AccessToken;
You can now query the Data Export API by providing the token as a header:
Authorization : Bearer eJ0y........Hgzk
curl -X GET --header 'Accept: application/json' 'https://discovery.crmreplication.azure.net/crm/exporter/profiles?organizationId=MyOrgId&status=true'

'Insufficient Privileges' error while using 'addKey' action in Azure AD Graph API

I have an application registered in Azure AD which uses certificates. I am trying to write a script which would add a new certificate to the application. This can be used to add a new certificate when the existing certificate is going to expire.
I am trying to use AddKey function of Azure AD Graph API. The request body of this api as a parameter 'proof' which is a JWT assertion signed by the existing certificate of the application. The doc says the "aud" claim in JWT should be set to "AAD Graph SPN". Here what is meant by "AAD Graph SPN"?
I tried with a JWT where "aud" was set to "00000002-0000-0000-c000-000000000000". But I am getting the following error,
{
"odata.error": {
"code":"Authorization_RequestDenied",
"message":{
"lang":"en",
"value":"Insufficient privileges to complete the operation."
}
}
}
Any thoughts on this?
I am getting the access token to call the Azure AD Graph API via "Resource Owner Credentials Grant" flow . To get the access token i am using the client_id "1950a258-227b-4e31-a9cf-717495945fc2" (The Well Known Client ID for Azure PowerShell")
My script (For deployment purpose) does something like below,
i) Get the access token as described above and registers a new application in Azure AD with a initial certificate.
ii) When the initial certificate is about to expire it should add a new certificate to the created application.
According to the documentation, you must use a self-signed JWT token to access that API:
As part of the request validation for this service action, a proof of
possession of an existing key is verified before the action can be
performed. The proof is represented by a self-signed JWT token. The
requesting application needs to generate a self-signed JWT token with
the following requirements...
The "Resource Owner Credentials Grant" won't work here in this situation. Instead, use the "Client Credentials Grant":
https://learn.microsoft.com/en-us/azure/active-directory/develop/active-directory-protocols-oauth-service-to-service
The application you want to update should be the Client ID used to get this access token.
The other option is to update the application directly using an PATCH request on the Application Object:
https://msdn.microsoft.com/en-us/library/azure/ad/graph/api/entity-and-complex-type-reference#application-entity
Using this method, you should be able to update using the method you described above (user credentials and an external Client ID)
Let me know if this helps.
