We have a federation between with our ADFS and the other company Azure AD using the "Claim Provider Trusts". We use the Azure AD to perform the authentication, but our ADFS/AD is sending some claims to our "Relying Party Trusts".
The problem I'm facing is if a user is disabled/expired in our local AD, it is still possible to authenticate and access the applications, because the user is not disabled/expired in the Azure AD. I can't manage the Azure AD and it is a valid situation where the user is disabled/expired in our AD, but still working on the Azure AD.
How can I figure this out to prevent disabled/expired user from my local AD to access my apps?
Thanks!
In Azure AD you need to go to the user's profile and block the user's sign in under the user's profile > Edit > Settings
You do need to have at least the User Administrator role in Azure, so if you don't have access to the Azure AD you will need to ask an admin to do this.
You can also use Graph API to set accountEnabled to false.
PATCH https://graph.windows.net/myorganization/users/{user_id}?api-version
Body:
{
"accountEnabled": false
}
Otherwise you can delete the user in Azure or ask the admin to do that.
For federation, the user should either be in your AD or in the other parties AAD.
(If you use AAD Connect, the user status is synched up to a shadow account).
Otherwise, you end up with this problem.
Is there a reason you have them in both?
Is there a way to match the AAD and the AD user?
If so, you can have a claims rule to get the status of the matching AD user and then deny access if disabled.
Update
You should read up on AAD Connect. It has filters e.g. groups so you can control who is synched up. Once that's working, if they are disabled in AD, then they will be disabled in AAD as well.
You should also look at the application report as it shows apps that can easily be moved to AAD and provides scripts to do so. There's a number of tools.
You could use the claims rules to find the enabled status of the user and then set a claim if disabled and then use the Access Contol Policies tab to deny access if this claim exists.

I am trying to setup Azure AD integration with our partner identities. I have few providers that I need to support and they support SAML and WS-Fed. I am trying to use Azure AD External Identities to add these providers to my Azure AD tenant.
However, reading through this article, it seems like SAML integrations are invitation based.
I want users to be able to login without an invitation. How can I do this with Azure AD?
Here are my needs:
After adding the external idp, users should be able to login using their own credentails via their idp. No additional information needed to use an app.
I should be able to grant them access to custom apps (mandatory) and azure resources (optional)
Choose what idp's are allowed per app? (if possible)
Thanks in advance.
Question 1: After adding the external idp, users should be able to login using their own credentials via their idp. No additional information needed to use an app.
Answer:
We can implement Guest users redemption using direct link or a common endpoint instead of email invitation. A guest user clicks the app link, reviews and accepts the privacy terms, and then seamlessly accesses the app.
Using Common endpoint : Guest users can now sign in to your multi-tenant or Microsoft first-party apps through a common endpoint (URL), for example https://myapps.microsoft.com. Previously, a common URL would redirect a guest user to their home tenant instead of your resource tenant for authentication, so a tenant-specific link was required (for example https://myapps.microsoft.com/?tenantid=). Now the guest user can go to the application's common URL, choose Sign-in options, and then select Sign in to an organization. The user then types the name of your organization.
Using Direct Link: As an alternative to the invitation email or an application's common URL, you can give a guest a direct link to your app or portal. You first need to add the guest user to your directory via the Azure Portal or Powershell Then you can use any of the customizable ways to deploy applications to users, including direct sign-on links. When a guest uses a direct link instead of the invitation email, they’ll still be guided through the first-time consent experience.

Question 2 : I should be able to grant them access to custom apps (mandatory) and azure resources (optional)
Answer: Add the Users as Guest to Azure active Directory but by default they will be sent an invitation even if they don’t open it you can assign an app in your enterprise application for them to use .
Most federated applications that support SAML 2.0, WS-Federation, or OpenID connect also support the ability for users to start at the application, and then get signed in through Azure AD either by automatic redirection or by clicking on a link to sign in. This is known as service provider-initiated sign-on, and most federated applications in the Azure AD application gallery

Quickstart: Add guest users in the Azure portal - Azure AD
To Provide the Guest user access to azure resources you can manually add a role to the users.
Question 3: Choose what idp's are allowed per app?
Answer: Create different user flows and add desired IDPs to the user flows and then assign applications registered in Azure AD to the user flows depending on which IDPs are needed for given application.

Question 4: I added Okta as an External Identity using SAML in my Azure AD. Created an "App Registration" as multi-tenant. But I am getting this error.
AADSTS50020: User account 'xxx' from identity provider 'http://www.okta.com/xxxxx' does not exist in tenant '' and cannot access the application '0000000c-0000-0000-c000-000000000000'(Microsoft App Access Panel) 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.
Solution: Please Ensure User is added to one of the Partner Admin Groups i.e. AdminAgents in the Partner tenant.

Question 5: Steps for setting self service signup for an application.
Test Scenario in my Lab
Azure AD with an application registered in application registrations blade.
Another AD tenant with users.
Step 1: In the above external identities collaboration settings please make sure to have enable guest user self service enabled.
If it is not enabled then you can’t create a self service flow and you will get the below error when a user from other tenant is trying to access the app.
Step 2: Create a user flow by going to the user flow blade and creating a new flow.
Step 3: After you have created the user flow , click on the User flow and go to application blade and click add application.
Now search for the application you want to provide the self service signup to and click on select and you will have now enable the self service sign up for users when they try to access your application.
Output:
Once the above settings are done you can access the url to your app. Provide the user of the different ad tenant and you will get output as below .Click on create a new one .
Once the user from other AD tenant have accepted it they are successfully registered as guest users in your tenant.
If they accept the above then they will be able to access the app from now as a guest.
I have a Web API that is registered in an Azure AD B2C directory, secured by tokens from that same directory. To do that I have created an Application and created a scope.
I have a 3rd party that would also like to use this AD for their audience, who will access some of my API on behalf of the guest.
I wanted to create a new scope for this purpose and have the AD prompt the guest to allow the application to access their data on their behalf.
For some reason, when I create a scope I am only given the option of "Admin Consent". The "User Consent" fields that are shown in so many blog posts and instructions are not showing for me.
I have tried to register the 3rd Party Applications and API Applications in both the B2C blades and the AAD blades of the Azure Portal but the result is always the same.
Is there a Property or setting somewhere that needs to be ticked in order to enable User Authorized scopes?
There’s no such thing as OAuth2.0 consent in AAD B2C, only Admin consent is offered, as it’s aimed for your first party apps.
The user consent screens you’re seeing online are in regards to Azure AD, not AAD B2C.
For service partner integration, you can follow this example to create such a consent. https://github.com/azure-ad-b2c/samples/blob/master/policies/service-consent
Let us assume I am an admin who is managing an Azure AD for my organization with about 3k users. All these 3k users have a login in Azure AD, and use a variety of Office365 services like Exchange Online, Microsoft Teams, Word Online etc.
Now, let us say, for some feature in Okta, we choose to federate our Azure AD with Okta, then what happens in the following scenarios :
Say there are as mentioned above the 3k users in Azure AD, only me in Okta, and I federate Azure AD, what happens? Is it like, the moment we federate Azure AD with Okta, everyone in our Azure domain can't login immediately? Or is there any possibility of doing this in a phased manner?
Say after all the 3k users now have an account in Okta as well. Can we maintain continuity? I.E after the users login to Azure AD via Okta, will they still see all their earlier data in Exchange Online, Teams, etc.
I assume there would be a mapping procedure to ensure continuity? How does that work?
There are a couple of things to take care of to ensure there is zero downtime:
AzureAD requires two attributes UPN (User Principal Name) and ObjectGUID to be passed from Okta. If your AzureAD and Okta users are both sourced from on-premise AD you will be fine, else you will need update AzureAD users to match the values with Okta.
Once federated with Okta, legacy authentication is disabled by default. If you need it, please make sure you update client access policies are updated accordingly in Okta
Federation with an AzureAD domain is big-bang but if you have multiple domains, you can federated them in a phases.

Thank you
I have an ASP.Net core web application and integrated authentication using the Azure AD B2C Tenant/Application. I'm able to authenticate and get the user claims in my web application.
But what I additionally want is to allow only certain customer users access the web application. I want to do this at the B2C Tenant itself. Right now any B2C customer user can sign in. Any help, ideas, insight will be appreciated.
You may know there is an Manage user assignment for an app feature in Azure Active Directory. But it's not available in Azure B2C.
Currently the recommended way to control the access in Azure B2C is defining custom attributes and check the claims in token.
If the expected claim is included, you allow the user to continue.
I try login to Azure AD web app and when i do it with user inside my tenant its ok,
but when login other user i get

Few things to check -
Based on the error you shared, it seems you're logged in with some Microsoft account like live.com/hotmail etc. Are you doing that intentionally or just happened to be logged in and getting confused by that? If you do want to login with a Microsoft account other than a usual organizational account, then as the error says, you need to add that account to your AzureAD tenant as an external user.
AADSTS50020: User account '*******' from identity provider 'live.com' does not exist in tenant
For any other organizational user, i.e. user from a different AzureAD tenant than the one where this application is registered, you will first need to go through the consent process. You may have done it already or not.

Issue:
You wanted to use a personal account within a multi-tenant application to get a token for the "https://management.core.windows.net" API
Scope:
We will focus on this issue and consider it as resolved once we provide you with the reason that Personal accounts cannot be used against a v1 multi-tenant application.
Alternatively, we will consider this case resolved if we confirm that the problem is caused by a third-party application or is by-design.
This agreed resolution statement describes the specific conditions where we will close this case. Please let me know if you do not agree with this scope.
Cause:
For multi-tenant applications in v1 you can only use an organizational account and not a personal one. That happens because for personal ones you will be logged authenticated by the “Live” endpoints and not by Azure endpoints, also because we are sending the user to the “common” endpoint and in there we do not know in which directory you want to sign in.
Resolution:
Having a multi-tenant application and sign-in users with personal and organizational accounts can be covered by the Azure AD V2 endpoints, nevertheless the v2 has some limitations right now and one of them is that you could only get a token for Microsoft Graph API and not for https://management.core.windows.net. We plan to implement all APIs that are available in v1 also in v2, but as for now cannot be used to acquire a token for such API.
