I am trying to create a POF with Azure Active Directory because I am planning to use it later in a production application.
In Microsoft docs, the only way I found to login is being redirected to the microsoft page to provide username and password.
Is there some API I can use to get the access token providing username and password? and I can test it, for instance, using postman.
You could use Resource Owner Password Credentials(ROPC) flow to get access token. See the Important first to make sure you could use it in your application.
The Microsoft identity platform endpoint only supports ROPC for Azure AD tenants, not personal accounts. This means that you must use
a tenant-specific endpoint
(https://login.microsoftonline.com/{TenantId_or_Name}) or the
organizations endpoint.
Personal accounts that are invited to an Azure AD tenant can't use ROPC.
Accounts that don't have passwords can't sign in through ROPC. For this scenario, we recommend that you use a different flow for your app
instead.
If users need to use multi-factor authentication (MFA) to log in to the application, they will be blocked instead.
ROPC is not supported in hybrid identity federation scenarios (for example, Azure AD and ADFS used to authenticate on-premises accounts).
If users are full-page redirected to an on-premises identity
providers, Azure AD is not able to test the username and password
against that identity provider. Pass-through authentication is
supported with ROPC, however.
Try executing this request to obtain access token.
POST https://login.microsoftonline.com/{tenant}/oauth2/v2.0/token
client_id=<your-app-id>
&scope=<scopes-in-api-permissions>
&username=<username>
&password=<password>
&grant_type=password
As you are looking to get an access token by sending the username and password
you can go with a postman or a curl operation
POST {tenant}/oauth2/v2.0/token
Host: login.microsoftonline.com
Content-Type: application/x-www-form-urlencoded
client_id=6731de76-14a6-49ae-97bc-6eba6914391e
&scope=user.read%20openid%20profile%20offline_access
&username=MyUsername#myTenant.com
&password=SuperS3cret
&grant_type=password
curl -X POST -d "client_id=clientid&scope=user.read&grant_type=password&username=username&password=Password" https://login.microsoftonline.com/tenantid/oauth2/v2.0/token
Note :Microsoft recommends you do not use the ROPC flow. In most
scenarios, more secure alternatives are available and recommended.
This flow requires a very high degree of trust in the application, and
carries risks which are not present in other flows. You should only
use this flow when other more secure flows can't be used.

I am having trouble getting an access token using the password grant auth end point.
I created an app registration in my Azure account which is tied to my personal live.com Microsoft account.
In the application settings I've set the supported account types to AzureADandPersonalMicrosoftAccount (Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox))
When I attempt to to authorize via my personal account's username/password using the https://login.microsoftonline.com/{{TenantId}/oauth2/v2.0/token end point using grant_type=password I get the following error:
AADSTS50034: The user account {EmailHidden} does not exist in the xxx-xxx directory. To sign into this application, the account must be added to the directory.
I am not sure how this is possible as I am obviously the only member of my Azure AD.
The app, Todo Inventory is listed under the applications in the user profile as shown below:
Note that I am successfully able to get an access token using the auth code flow described in the documentation here: https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-auth-code-flow
But I want to use the password grant instead but nothing I tried seem to be working.
Am I missing something here..?
Microsoft identity platform doesn't support resource owner password flow for personal accounts. https://learn.microsoft.com/azure/active-directory/develop/v2-oauth-ropc

I'm in a pickle, lacking the experiences that would provide me with guidance in my project and am seeking pointers from those for whom have Azure AD, SSO and Federation experience.
I am building an employee self service system and using Azure AD for identity management. I would like the user to be able to sign in using their employee ID # and password, not their email address; there should also be an option for the user to register for online access using their employee ID # and other personal information - their Azure Identity already having been established by humane resources.
The sign in flow would take the user to the Microsoft login page which would in turn detect that the user needs to sign in via a custom login page and redirect them there. Once they are signed in, my server would transmit their identity to Azure AD and grant them access based on the Azure Application permissions.
I'm simply really confused about how to start setting this up, if it's even possible. I'm aware of XSS but isn't Federation and SSO with SAML2 secure?
Do I need to use a federation application as a middle-man such as Ping Identity?
Thanks for any help!
Using e.g. Ping as an IDP generally won't help because Azure AD is already an IDP.
Microsoft Azure AD login pages can't be accessed by API and can't be customised to the extent you want.
And you can only sign-in with an email address because it's designed for domain-joined corporate customers.
You can do a lot of what you require with Azure AD B2C and custom policies. That will allow you to sign-in with a user name (= employee id) and you can create workflows.
You could then federate Azure AD and Azure AD B2C.
Your other option is to use an IDP that does allow authentication via an API e.g. Auth0.
Then you could have a custom login page that authenticates as appropriate.
Using Ping ID and other similar products is the fastest way to utilize SSO.
I have searched far and wide to find out how I can change the settings of my Microsoft Graph app so I only allow login from my own domain.
Since the login from Graph takes all Microsoft accounts i've been looking into different solutions, all from finding custom token endpoints to changing the application manifest.
In my manifest I can find this "signInAudience": "AzureADandPersonalMicrosoftAccount" - but I can't find in the documentation what other options there are.
also on this Microsoft page I can find this information
The overall solution comprises the following components:
Azure AD – If the Restrict-Access-To-Tenants: <permitted tenant list> is present, Azure AD only issues security tokens for the permitted tenants.
Is there any good guides online or anyone who knows how i can restrict access to people signing in either with #xxxxx.comonly or xxxxx.onmicrosoft.com accounts?
I think you're misunderstanding how Microsoft Graph works. It connects to the tenant/domain of the user authenticating. So if I authenticate with user#contoso.com, the application will only have access to the contoso.com tenant.
In terms of the authentication process itself, this is handled by Azure AD. Microsoft Graph simply accepts the token AAD returns. You can limit this process to users from a given tenant by changing the /Authorization and /Token URLs your app is using.
In most cases, apps use the /common tenant. When a user authenticates against /common, AAD handles discovering the user's actual tenant/domain and routes the request to that AAD instance for processing. These URLs look like this:
https://login.microsoftonline.com/common/oauth2/v2.0/authorize
https://login.microsoftonline.com/common/oauth2/v2.0/token
If you want to limit authentication to a single tenant, you can skip the discovery process and force AAD/OAuth to authenticate against a single AAD tenant. Only users that exist in that tenant will be able to authenticate. This is done by swapping /common with tenant's id:
https://login.microsoftonline.com/xxxxx.onmicrosoft.com/oauth2/v2.0/authorize
https://login.microsoftonline.com/xxxxx.onmicrosoft.com/oauth2/v2.0/token
Sorry I am still very confused, read everywhere telling me oath is a authorisation protocol but it appears using the azure ad oauth code grant, it does promote a login screen to authenticate against the directory, so is it not an authentication process? what is the relationship between the open id connect? thanks!!
the OAuth2.0 protocol has several flows that an identity provider (in your case Azure AD) may implement to support auth.
The Auth Code flow is in fact one of these used by apps to get access tokens for some api. The flow is quite simple, an app redirects the user to the identity providers /authorize endpoint. At this point the user enters their credentials, and the site redirects back to your application with an authorization code and can also issue an ID Token that represents a user (This is the OpenID Connect part). The app takes this code, and POSTs it to the /token endpoint and will be issued an access token and refresh token. With the access token, your app can access whatever api you've requested access for.
For Azure AD specifically, Microsoft has built libraries that handle all these flows and token caching so most of the complexity is abstracted away. There's some simple code samples that you can checkout that you may find helpful. The authentication protocols and scenarios doc for Azure AD may also be really helpful for conceptual information.
I'm currently trying to implement a multi-tenant Azure AD application that will use Microsoft Graph API's to monitor and analyze Office 365 "metadata" for members of the tenant domain. For example, the application might monitor One Drive user space over time. The architecture of the application will include an AngularJS SPA client along with a web application back-end. The idea is that the web application allows for both local registration (e.g. traditional sign up using an email address and password) in addition to Azure AD authentication. In the case of local registration, the user might be able to associate an Azure AD tenancy with the local account in the future, for example.
I'm struggling to understand how various authentication mechanisms should work. For example, I think that there should be two levels of authentication in the case of Azure AD: one authentication for the users of the client SPA, and another authentication used by the back-end for making continuous calls to the Microsoft API's, requesting refresh tokens, etc.
How might this architecture be implemented using the various Azure AD authentication scenarios Microsoft has already provided examples for?
If my initial inclination that I will have two applications registered with Azure AD (for example, the SPA registered as a native application, say, and the web application registered by itself), how will users allow access to both of them, and what would this workflow look like? In addition, what would the flow of user requests look like? The SPA would make a request to the back-end using its Azure AD token, but what will the back-end do to receive its authentication token and make calls to the Microsoft API's?
How might I best incorporate Azure AD authentication along with local registration into my application?
Generally speaking, you can associate your each user to his entity in Azure AD tenant in your backend server / database. As every user in Azure AD has several unique properties in the entity object. You can use the user's email or objectId as mentioned at Claims in Azure AD Security Tokens as the external column in your user table.
When your user authenticate your site via ADAL.JS, you can grab the access token in your backend server via the Authentication header. You can use the access token to request for the resources protected by Azure AD. And the access token is a JWT token, which you can decode directly to get the user basic claims as we mentioned before. You can retrieve the claim which you stored in your user table and match the special user registered in your server for requesting the resource protected by your self.
