I have succesfully configured IBM Domino authentication against Active Directory for web users by following the
https://www-10.lotus.com/ldd/dominowiki.nsf/dx/Streamlining_passwords_and_achieving_SSO_for_users_on_Windows_platforms .. and .. http://www-01.ibm.com/support/docview.wss?uid=swg21293255 tutorials. Now user can authenticate even there is no Person document in my Domino directory. Is there a way how to avoid authentication when Person document missing for particular user?
Based on this tutorial and 'step 2' section I assumed, that when I dont specify LN user name in AD then Domino tries to find Person document in names.nsf based on user's email. But it doesnt work this way. Without specifying Notes name in AD, Domino server have no idea what is Notes user name for just authenticated user. Is here any way how to configure this in a way, that Domino authenticates only users available in names.nsf and not all these in AD?
I'm not sure what You have and what You want to avoid, but, here are few notes that might clear things:
You don't need DA for Kerberos SSO to work
DA allows "all" AD users to login
After login, You need authorization (as Frantisek Kossuth wrote)
authorization can be set with AD names - You don't have to have Person documents
TDI is best solution - You can "copy" just AD users that you want in Domino, and set SSO for them (you have already)

As the title says, I have a user "User1" in a group "Techs" and "Techs" is a Role Enabled Azure AD, Cloud Only, Security Group that is assigned both the Exchange Administrator, Helpdesk Administrator and Exchange Recipients Administrator roles.
User1 is able to powershell and use most cmdlets for mailbox management, but is unable to access the EAC. Attempting to access EAC sends User1 to a mailbox management page for their own mailbox, and attempting to Edit Mailbox Properties for a user in the Microsoft 365 Portal greets User1 with a 403 forbidden page.
Direct assignment of exchange admin role works, but defeats the purpose of using a group. Anyone else experience this or know how I can fix it?
Currently, it is possible to switch back to the existing EAC (often called the "classic" EAC), but at a future date, the classic EAC will be retired.
But I suggest not to use "classic" EAC for work because according to my test, the methods listed here cannot allow the exchange admin to manage the mailboxes in the tenant.
It's recommended to access new EAC using these 2 methods.
Sign in to Microsoft 365 or Office 365 using your work or school account.
In the left navigation pane, navigate to Admin centers > Exchange.
You can also get to the new Exchange admin center directly by using
the URL https://admin.exchange.microsoft.com and signing in using your
credentials.
As the document suggests, Be sure to use a private browsing session (not a regular session) to access the Exchange admin center using the direct URL. This will prevent the credential that you are currently logged on with from being used.
In this way, your user which is assigned Exchange Admin role with Group inherit way should be able to access EAC successfully.
Is there a way to get value of "objectIdentifier" claim for Microsoft account?
Case: I have an app with one form field, email (need's to be Microsoft account). When this email is entered, server (back end) need's to find out value of object identifier (user ID) in common tenant for all Microsoft accounts (section "tid").
Normally, if this was normal tenant in Azure Active Directory I would create Azure AD app and generated client secret for accessing Graph API, directory endpoint. Unfortunately, this is "special" tenant and I don't know is there any API I can call (as application) to get id of user (best option would be GetUserIdByEmail(email)).
I understand this is weird case but life is hard :)
Asking user to login and then retrieving value from token is not an option!
There is no API that I'm aware of where you could query for MS personal accounts' info without logging a user in.
If you think about it, it would be quite an easy source of building a user list for attacks :)
You will need to log them in to get their id, I don't think you can know it in advance.
I am added to project collection administrator group in VSTS. Still not able to add a new user. I am added using my official email ID i.e. Microsoft work account.
Its says
Guest users are not allowed to perform this action.
I saw the reason on this link
I believe the primary reason for this error is because when a co-admin
with Microsoft account is added to a subscription, it gets added into
the subscription AD as Guest user type.
but since it is very old thread i like to know if there is an easy way to get myself ability to add new user or basically manage VSTS on behalf of client. I hate requesting client to add a new user in team. Also he is not tech savvy so I would like suggest him a simple solution (running Powershell might be annoying for him).
You are inviting users from outside directory. The user will be able to access the account and its resources, so you need the enough permission to add new user to the AD, but you are the Guest user, so it throws Guest Users are not allowed to perform this action.
You need to contact to the corresponding user (e.g. AD admin) to add users to AD or grant the enough role and permission to you to add user to AD.
No easy way to do this, because it is related to security.
In AAD, one could
add new Users to the same Domain
add Guests:
from other AAD Tenancies, passing through credential verification to the other Tenancy
from Microsoft Account users, passing through credential checking to live.com
But I'm noticing today although it still accepts to invite MA users, when they sign in, they are asked to create a Password.
From then on, they are shown the usual "Do you want to use your personal account or org/school account".
Is this a new change?
Should be no longer be inviting personal accounts, and stick to only inviting users within other Tenancies (so they don't get asked whether to use Pers/Work account when signing in)?
What happens when they create a company around their own email...will they be able to wrest back resolution of the credentials -- or will it always stay with the first tenant that imported a personal account!?
Thanks for help understanding how this aspect of Azure AD works.
Our application (referred to as "XYZ_App" below) is a multi-tenant SaaS application. We are in the process of making it available for Microsoft AppSource as a multi-tenanted "Web app / API" (referred to as "AppSourceXYZ_App" below).
We started our OpenID Connect implementation with endpoints pointing to “common” as per stated in the documentation when multi-tenancy is desired/required.
In XYZ_App, we added information in the system to know what AAD instance each XYZ_App tenant is associated with (using the GUID Microsoft assigned to this AAD instance, we are NOT using the "rename-safe.onmicrosoft.com" representation).
When using the “common” endpoints, we had to manually validate the issuer from the JWT to make sure it was the expected one: a user could access XYZ_App requesting access to XYZ_App’s tenant associated with contoso.onmicrosoft.com, get directed to “login.microsoftonline.com/common” to authenticate and then decide to authenticate with a user from another AAD instance (referred to as "anotherAADInstance.onmicrosoft.com" below). In this scenario, even though a user could successfully authenticate on anotherAADInstance.onmicrosoft.com, XYZ_App’s redirect URI must make sure the JWT issuer is the one from contoso.onmicrosoft.com. I’ll refer to this setup as Scenario_1.
With that scenario in mind, we thought about NOT using “common” and customize the requests going to login.microsoftonline.com on the fly; attempting to “jail” requests to be forced to authenticate against a specific AAD instance. We would still need to perform our validation in the redirect URI to make sure the issuer is the appropriate one, but we thought this approach might make our lives easier. I’ll refer to this setup as Scenario_2.
Do you envision Scenario_2 is viable in the long run or is it too short-sighted ? Based on my current knowledge of OpenID Connect, one limitation I can see with Scenario_2 is that it would become problematic to support “broker accounts” into our app.
Explanation of “broker accounts”: in our industry, some external users are allowed access to the system. Let’s say I have a company called “BrokerCo” (with their own brokerco.onmicrosoft.com AAD instance) who has 2 employees: Broker1 and Broker2. BOTH anotherAADInstance and contoso hired Broker1 and Broker2 to get broker services to perform tasks in XYZ_App; requiring XYZApp to grant them access. What is the ideal way for authentication from an OpenID Connect standpoint ? If XYZ_App were to use “login.microsoftonline.com/common” for authentication (like in Scenario_1; as opposed to “jailed” access like in Scenario_2), Broker1 and Broker2 could authenticate with brokerco.onmicrosoft.com (no AAD "External users" for anotherAADInstance nor contoso), but they would then get to redirect URI with an issuer that is different than what XYZ_App’s anotherAADInstance and contoso tenants are configured for... I feel like I’m back to square 1...
Do you have suggestions or pointers to solve this issue ?
Background context:
While playing with OpenID Connect issuers, I got the following error message:
AADSTS50020: User account 'testuser#anotherAADInstance.onmicrosoft.com' from identity provider 'https://sts.windows.net/XXXXXXXX-fake-GUID-9bZZ-XXXXxxxxXXXX/' does not exist in tenant 'XYZ Publisher' and cannot access the application 'YYYYYYYY-fake0-GUID-YYYYyyyyYYYY' 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.
Thanks in advance !
Your question has multiple layers, trying to address most of them:
AppSource is about trial experiences for new users: this mean that any corporate account around the globe can potentially be an user of your SaaS application - or at least to the trial experience of your application, therefore the first thing you need to think when integrating with AppSource is how easy it has to be for a potential user to experience your app for the first time.
With that in mind, AppSource recommends that the trial of application is build on such a way that allows any user from any organization to sign-in, and therefore a multi-tenant approach for your application is the recommended setup for any application.
The single-tenant approach requires more control on your side, and for a trial experience - it means that the user cannot try your application right away because the operation you have to do on your single-tenant application is to add the user to an Azure Active Directory tenant as a guest user. This guest account will need then to wait receiving an email to accept the invitation to join to this tenant you are adding the user to then sign-in to your application.
Therefore your scenario 1 is the best scenario thinking on a trial experience in general, and also in general require less management (as you'd not need to create/ manage each individual account that needs to access your application as guest users of your Azure AD instance).
However some concerns you listed - that this scenario bringing are valid: Because you are accepting the common endpoint, you are saying basically that any user can sign-in to any tenant to your application, and this may not be desirable. In addition, the scenario you listed that a user can generate a token for any application is also valid, however, you can add additional checks to make this more secure and that any token generated by another authentication is blocked:
You can validate the 'audience' claim to guarantee that the token was issued to your application
You can eventually check the 'tid'/'iss' claims against of a list of tenant Ids in your database to see if that the user's organization is a valid organization in your application -- this would be valid for non-trial users/ organizations.

About scenario '2' and broker accounts:
This scenario could be interpreted in two different ways:
Broker accounts are guest accounts of a customers' Azure AD tenant
Broker accounts are third party accounts but are not actually added as a user of anotherAADInstance or contoso AD
If your case is '1' then you're right: if your application needs to authenticate guest users that belong to another Azure AD tenant, then common endpoint could not be used directly.
If your case is '2' then what you'd need to do is to continue using the common endpoint and somewhat after the user is authenticated ask them to choose the company. I am describing this on generic terms without fully understanding this scenario. Perhaps this is not simple as you want the remote company to control this and not the user - so some additional complexities may need to be handled here.
A note is that if your scenario is scenario 1. - in theory - you can still use an hybrid approach, where you'd ask user to type the username inside the application and the company that they want to sign-in, then check if you need to validate the user against common or tenant-id endpoint, preparing the request and then sending a login_hint argument when authenticating.
