I am stuck at this issue while sending request for Azure Active Directory authentication from ASP.NET, using UserPasswordCredential, I get this error :
{
"AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '00000002-0000-0000-c000-000000000000'
Note : MFA is enabled.
Does any one know why this issue occur ? how to ignore MFA authentication while authenticate from API side.
Is there any policy to handle MFA authentication?
The documentation for UsernamePasswordCredential Class clearly states this will not work:
Enables authentication to Azure Active Directory using a user's username and password. If the user has MFA enabled this credential will fail to get a token throwing an AuthenticationFailedException. Also, this credential requires a high degree of trust and is not recommended outside of prototyping when more secure credentials can be used.
For an alternative solution, please see the documentation on Managed identities for Azure resources.

I need to support 3 way of authentication at the same time in the application: LDAP, Azure AD, Basic.
After few hours of googling i found that the best way to do it would be to implement 3 authentication providers and then register them with AuthenticationManagerBuilder. But the issue i stumbled into is, that i dont know how the make the Azure Ad provider. For LDAP i found an online example i can use, and based on the LDAP i could probably also make the Basic username and password provider, but havent found anything similar on Azure AD. All i have found is that, i need to add 2-3 dependencies to the project for the Azure AD and then it automagically works.
I dont understand spring security that much, so im stumped atm. Can i just trust the automagic to do everything correctly, or are there some resouces on how to create AzureADAuthenticationProvider i could use with AuthenticationManagerBuilder?
An authentication provider is an abstraction for accessing user information from LDAP, custom third-party source, database etc. it validates the user credentials.
Spring security with azure ad:
Firstly, azure ad is integrated with Spring security for secure your application.
User login through their credential and get validate by azure AD.
From azure graph API you have to access token and membership information.
Membership for role based authorization.
LDAP Authentication:
Unique LDAP or DN ,you can perform search in directory unless you know username to DNS is known in advance.
You can authenticate the user by binding that user.
Load the Number of authorities for the user.
Custom Authentication Provider:
Create own authentication (custom) with the help of authentication provider interface in which you can use
authenticate method and implementing it and make authentication object with username and password of user
Then after you can configure these authentication in spring security configuration.
Here is the Reference Link regarding Spring Security
For our B2C Tennant we want to let our customers make use of the Microsoft Authenticator app. When doing research, we noticed that it was not possible to add the Authenticator App for existing users without disabling phone/text message authentication.
This is not an acceptable situation for us since that means that someone with customer credentials can take over the enrolment flow.
A MS engineer suggested the following:
The desired situation should be possible with a “Registration
campaign” -
https://portal.azure.com/#blade/Microsoft_AAD_IAM/AuthenticationMethodsMenuBlade/RegistrationCampaign
Users will go through their regular sign-in, perform multifactor
authentication as usual, and then be prompted to set up Microsoft
Authenticator.
However, we enabled this option as described in the Documentation, but after an existing user signs in no Authenticator App Flow is started.
Does someone have experience how we can make this work?
As far as I know, even after enabling MFA if existing users don't receive authenticator app approval, please try below steps:
There is a chance of where your users selected “Stay signed in” while logging into their accounts. By doing this their devices will be treated as remembered device that suspends enabling MFA.
While enabling MFA if you set Remember MFA on trusted device , then the user won't get prompts until the duration expires
To resolve the issue, try clearing all old sessions history, by enabling “Revoke MFA sessions”
If the issue still persists, try enabling Re-register MFA, that asks the users to set up a new MFA authentication method when they sign-in.

I have the following requirement:
create a user on AD B2C.
using the credentials of that user, I need to get access token and refresh token to access an existing api(REST SERVICE).
Active directory here is Azure AD.
I am new in oAuth and Azure. Please suggest me the steps and configuration to achieve this. (I do not want any user interaction to get access token and refresh token).
creating a user is clear to me. but if it requires any specific type of user or any required permissions, please suggest those.
To me, it sounds like your use case can be better realized with a service principal. If you don't need a user context but, consider using an SP instead. See:
Microsoft identity platform and the OAuth 2.0 client credentials flow
If for whatever reason you want to stick to non-interactive user login, you can use the Resource Owner Password Credentials flow. But be aware that:
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 have an app registration on Azure that is being used to authenticate requests using the ROPC flow, so that we can mimick a real user access token and test our APIs. This is working, but to make this more secure we would like to be able to say a secret is required in the request.
This is not default for ROPC as it wasn't intended to be used with secrets (note - we cannot use client credentials for this part of testing we are doing).
The app registration is used along with a B2C user flow setup along side it. I don't believe this to be too relevant for this issue, but I could be wrong.
Currently the working call is as follows -
On azure to allow the ROPC flow you need to set the application to allow public flows.
I believe this setting stops any form of client secret or certificate being required in the request.
The microsoft docs seem to suggest it is possible to add a secret to ROPC calls and make them required but i can't figure out a way of doing it while having the above "public" azure setting set to true. With that off you get an error saying that the resource owner flow is not allowed due to it being private.
This is part of the Microsoft docs - https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth-ropc which seems to suggest you might be able to make the app private, I just can't see how while allowing the flow.
This link you mentioned is about Azure AD, but not Azure AD B2C. So there are two methods to get the access tokens with different formats. In addition, it's more secure for you to use authorization code flow in Azure Active Directory B2C.
One is following AAD Docs with your AAD B2C directory, see the explanation. Note: scope doesn't support application-id, it's related to the permissions in API Permissions.
POST https://login.microsoftonline.com/{b2c-tenant-name}.onmicrosoft.com/oauth2/v2.0/token
client_id={b2c-application-id}
&scope=openid offline_access
&username={username}
&password={password}
&grant_type=password
&client_secret={client_secret, if your app is not a public client}
[Recommend] Another is testing ROPC flow in Azure AD B2C. client_secret is not in the parameters, so it is not required whether it is public or not.
https://{b2c-tenant-name}.b2clogin.com/{b2c-tenant-name}.onmicrosoft.com/{B2C_1_ROPC_Auth, name of ROPC flow}/oauth2/v2.0/token
username={username}
&password={password}
&grant_type=password
&scope=openid offline_access {b2c-application-id}
&client_id={b2c-application-id}
&response_type=token id_token
We have an application that supports seamless login with our Azure AD tenant account via OpenID Connect implicit flow. If user is authorized to access the app providing Azure AD issued evidence - access will be granted automatically, otherwise we show regular application login screen.
Every time when user authentication is required we redirect the user to the Azure AD login page (https://login.microsoftonline.com/xyz) specifying prompt=none.
Respecting the ODIC specification such flag should have the following effect.
The Authorization Server MUST NOT display any authentication or
consent user interface pages. An error is returned if an End-User is
not already authenticated or the Client does not have pre-configured
consent for the requested Claims or does not fulfill other conditions
for processing the request. The error code will typically be
login_required, interaction_required. This can be used as a method to
check for existing authentication and/or consent.
It generally works as expected, however, there is a case where Azure AD login page will show an error screen to the End User and it happens when User logged into another Azure AD tenant.
User account '...' from identity provider
'https://sts.windows.net/.../' does
not exist in tenant '...' and cannot access the
application '...' in that tenant. The
account needs to be added as an external user in the tenant first.
Sign out and sign in again with a different Azure Active Directory
user account.
The questions are:
Does not it violate the ODIC specification?
How to properly handle such cases in seamless for users fashion? (app is not in charge of what is going on after redirect to Azure AD).
Though I also agree that this is a violation of the spec, can I offer a workaround?
I believe you can try specifying domain_hint or login_hint parameter as well to help the system determine valid session. Hope it would give you the right answer regardless of which session user is signed in at the moment.
Yes, this is a violation of the OIDC spec. We have created a bug.
If the error is only occurring because the STS is selecting the wrong session, you could use login_hint or domain_hint to help the STS select the right session.
Yes, that is in violation of the spec and defeats the purpose of prompt=none since the the application can't keep control of the user experience anymore. #vibronet may be able to set the record straight on MS side.
