I have SAML SSO setup made for an Active Directory. I have another tenant which contains an app service, a webapp, which tries to authenticate using the SAML connection details.
I'm getting:
AADSTS700016: Application with identifier was not found in the directory . This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.
Isn't it possible to authenticate with users from an AD for multiple applications from different tenants using SAML SSO?
External users won't be able to log in to the Single Tenant application. These users would need to be existing in the same Tenant.
Make your app as a Multi-tenent as per rbrayb.
Multiple application that has its own account system, or supports other kinds of sign-ins from other cloud providers, adding Azure AD sign-in from any tenant is simple. Just register your app, add sign-in code via OAuth2, OpenID Connect, or SAML, and put a "Sign in with Microsoft" button in your application.
Based on the error,
Try Solution 1:
Make use of Application Client ID, instead of using any other client ID.

We are developing a multi-tenant application that is hosted in Azure. We're using IdentityServer4 for handling authentication and authorization. Recently, we enabled the SSO by registering our application in Azure AD. We enabled the multi-tenant SSO in the App registration service. The SSO works fine and client users can sign in with their Azure AD.
The users are accessing the application by providing the URL in the following format https://myapplication.com/mytenant. When a user logs in for the first time consent is required and if accepted the user can successfully log into its tenant space.
After the first successful access, our application is added to the My Apps portal in Azure.
Our problem is that the URL in My Apps is pointing to the one provided in the Branding tab in App registration but not the one that the user logged in for the first time. Since this is a multitenant application every tenant has its own URL.
Is it possible for the first sign-in URL to be saved in the My Apps portal? We can do an Azure tenant - application tenant sync based on claims but that means a lot of trouble just for accessing the My Apps portal.
An administrator of each customer could add a linked "single sign-on" app in their organization and assign it to users, but there's no way to have your single multi-tenant app present in different tenants with different URLs.
What you could do instead is to have your (only) sign-in URL be a URL that triggers a sign-in (generically, on the "common" or "organizations" endpoint, instead of a tenant-specific endpoint). Once the user has signed in, then you'll know what tenant the user belongs to, and you could redirect them to the appropriate version of your site.
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've created a multi tenancy application so I could use the SSO options it gives me.
When trying to sign in with a user outside the domain of the app I get the following error:
AADSTS700016: Application with identifier <MY_APP_NAME> was not found in the directory <I_GUESS_THE_USERS_DIRECTORY_ID?>. This can happen if the application has not been installed by the administrator of the tenant or consented to by any user in the tenant. You may have sent your authentication request to the wrong tenant.
According to this question it's suppose to work without me having to do anything.
But, is it? what me or the organization should do in order to complete the process?
You need to also provision a service principal of your multi-tenant app in the target tenant. A detailed guide is available here.
There are four simple steps to convert your application into an Azure Ad Multi-tenant app:
1.Update your application registration to be multi-tenant
2.Update your code to send requests to the /common endpoint
3.Update your code to handle multiple issuer values
4.Understand user and admin consent and make appropriate code changes

So in the scenario like above is it not required to "Register the Application all of the Active Directories" from where the Users from different tenant may login to the Application ?
If not required to register what is the work around?
I have created a Web application in my local Azure AD which I can successfully use to authenticate members of my AD tenant with (using oAuth2 flow). Now I need to extend my supported scenarios to allow a global admin from an external Azure AD tenant to sign-up their company to use this application as well.
Based on the Microsoft Docs this scenario, Multi-Tenant, is supported...
Authentication Scenarios for Azure AD
Multi-Tenant: If you are building an application that can be used by users outside your organization, it must be registered in your company’s directory, but also must be registered in each organization’s directory that will be using the application. To make your application available in their directory, you can include a sign-up process for your customers that enables them to consent to your application. When they sign up for your application, they will be presented with a dialog that shows the permissions the application requires, and then the option to consent. Depending on the required permissions, an administrator in the other organization may be required to give consent. When the user or administrator consents, the application is registered in their directory. For more information, see Integrating Applications with Azure Active Directory.
From my reading it appears that at some point a global admin for the foreign tenant should be presented with a URL which they can follow ( login.microsoftonline.com/common/??? ) which will somehow cause the external application to precipitate like a morning dew into their Azure AD. However, if this is the correct approach I would appreciate a tokenized example of how one correctly builds the login URL for a multi-tenant external Azure AD application which a group admin can follow to allow access in their AzureAD.
Ok, through trial and failure I have found the solution. The group admin for the remote tenant needs to be provided with the following URL which will allow them to register your Azure AD application as an Enterprise Application in their tenant.
https://login.microsoftonline.com/{remoteTenantUrl.com}/adminconsent?client_id={YourAppsClientID}&redirect_uri={YourAppsCallbackPage}
I am using Azure B2C to connect my own openid connect server using OpenID onnect (Preview) provider. I configured every thing, system is working fine.
But one thing is when a new user logs in through my own openid connect server, Azure AD B2C creates this user in Azure AD which is connected to Azure B2C.
My intention is that, My client application has to call Azure B2C. Azure B2C should display list of identity providers. one among those providers is my own openid connect server. Then user can input his credential in my own openid connect server and verified and return back to Azure B2C with id_token. after this step Azure AD B2C is asking me to create this user in Azure AD. why this is happening ?
I cannot provide my user details to any intermediate systems. Please help me on this.
The same scenario is happening for gmail users also. but only first time login or when we change some signin policy attributes.
Based on my experience, even for externally authenticated users (social sign-in) AAD B2C always creates an object in its local store (which is actually an Azure AD directory). I can't speak authoritatively, but a couple of reasons for this would be 1) the ability to generate and maintain an immutable ID for a user that is somewhat independent of the social IdP, and 2) the ability to collect and store additional attributes which are not available from the social IdP.
I believe you can make the process invisible to your users - they don't necessarily have to be prompted to enter additional attributes or to create a user - but it will still happen in the background.
