Entra Hybrid Join - Problems with Server 2016 and userCertifiate
Dear Community, I am having some troubles with the hybrid join of a group of servers (Windows Server 2016). The basic problem is that Windows is not creating the required self signed certificate and therefore the AD attribute “userCertificate” is empty. As we now, while it is empty, the objects are not getting synced to EntraID. (A Mobile Attempt: Azure AD Hybrid Join and the UserCertificate Attribute) And I don’t find out, why this certificate is not created. As mentioned, it affects only some Server 2016, which are our RDS Terminal Server. All other Windows Server and Clients are successful synced and have a userCertificate (including other Server 2016). All our servers are VM, based on VMWare. Some more words about these RDS Server: They are cloned from a VMWare template The deployment process is as follows: o On a Master VM we install all updates / software It is domain joined and has a userCertificate o Master VM gets converted into a VMWare template o New RDS TS are created from this template With a configuration to reset SID and automatic domain join The have no userCertificate Test lab for troubleshooting I created some new VMs to test and verify the behavior. Here is what I did: Installed a new Windows Server 2016 VM from DVD Installed all latest updates Converted it into a VMWare Template -> Srv2016_Template This should be my new template for Server 2016 Created new VM from this template: Srv2016RDSMaster Used a configuration to generate new SID and automatic domain join This should simulate my Master template for new Terminal Server --> It has a “userCertificate” in its AD Object Converted it into a VMWare Template Created new VM from this template: Srv2016RDS01 Used a configuration to generate new SID and automatic domain join --> It hasno “userCertificate” in its AD Object Troubleshooting steps Networking No proxy, direct Internet No DENY on our firewall -> Internet available Verified that these URLs are accessible https://enterpriseregistration.windows.net https://login.microsoftonline.com https://device.login.microsoftonline.com https://autologon.microsoftazuread-sso.com Active Directory and Infrastructure Service Connection Point (SCP) is set in the forest and has the tenant name and ID (otherwise no computer would be synced) GPOs are not linked to the OU in which the computers are Local troubleshooting on the VM Scheduled Task for “Workplace Join” is enabled and runs dsregcmd /status EventLog – “Application and Service protocols” -> “Microsoft” -> “Windows” -> “user Device Registration” Two errors, each time the Workplace Join task starts: Sysprep Also tried on the VM a sysprep, rebooted, manually joined it to AD --> Still no userCertificate Tried the same again and deleted also the AD object --> Still no userCertificate Activated TLS 1.2 Enable TLS 1.2 on servers - Configuration Manager | Microsoft Learn -> no affect Articles I read and verified Plan your Microsoft Entra hybrid join deployment - Microsoft Entra ID | Microsoft Learn Configure Hybrid Azure AD Join - Everything you need to know A Mobile Attempt: Azure AD Hybrid Join and the UserCertificate Attribute Troubleshoot Microsoft Entra hybrid joined devices - Microsoft Entra ID | Microsoft Learn My conclusion I guess it has something to do with Server 2019. Why I am saying this: I have tested the same setup with an old, existing Server 2019 template (created “Master VM” -> converted into template -> created VM from this template) --> all VMs have userCertificates in their AD object So I would be glad if someone has ideas about it. Thanks, Chris
Group writeback doesn't sync back to Entra
Hi all Can't find documentation on this if this should actually work or not. I enabled group writeback, which works fine. Now if I add a user to one of those groups in local Active Directory and sync the user to Entra, the user isn't a member of the group here. Might be just normal behavior, but would be nice if it did sync.General Question About Federation
Hello, We have a federated domain and to my knowledge this means that all authentication for this domain will be send to ADFS and will not be directly handled in Azure Entra ID. Is the following statement correct: When I register an APP in Entra ID the authentication will still be handed off to ADFS. (when my user types in email address removed for privacy reasons. I will first go to microsoft that will then hand it off to ADFS. Will there by any additional config required on the ADFS server for the registered application? If i would like to bypass this federated authentication the only way to do this is change it to a managed domain removing the federation or do a staged rollout as described below Microsoft Entra Connect: Cloud authentication via Staged Rollout - Microsoft Entra ID | Microsoft LearnSCIM provisioning - custom app authentication
Hi, in the documentation for handling endpoint authentication, two methods are given: 1) a "long-lived token" (i.e. a secret key that has to be pasted in-clear by the admin) 2) "Microsoft Entra bearer token" - similar to other services (e.g. callbacks for MS Teams bots), Microsoft sign the outgoing calls, and the app being provisioned can validate them against Microsoft's public keys To me, option (2) is by far the best - each message is signed individually, there is no manual handling of secrets etc. As said in the documentation - "Apps that use Microsoft Entra ID as an identity provider can validate this Microsoft Entra ID-issued token." - great! So why on earth does it then say "The token generated by the Microsoft Entra ID should only be used for testing. It shouldn't be used in production environments."? Why not? The whole system of Entra bearer tokens is only for test? And production should go back to secret keys, with all the problems they have? It doesn't seem right.. What am I missing here?
'Microsoft App Access Panel' and Conditional Access with SSPR combined registration bug
Currently, enabling self-service password reset (SSPR) registration enforcement causes the app 'Microsoft App Access Panel' to be added to the login flow of users who have SSPR enabled. This app is not able to be excluded from Conditional Access (CA) polices and is caught by 'All cloud apps', which breaks secure zero-trust scenarios and CA policy configurations. Best way to demonstrate this is through examples... ----Example 1---- Environment: CA Policy 1 - 'All cloud apps' requiring hybrid/compliant device, but excluding [App] (for all non-guest accounts) CA Policy 2 - [App] requiring MFA only (for contractor accounts, etc) CA Policy 3 - [App] requiring hybrid/compliant device (for internal accounts, etc) SSPR registration enforcement (Password reset > Registration) - set to 'Yes' MFA registration enforcement (Security > Authentication Methods > Registration campaign) - set to 'Enabled' Scenario: A new user requires access to web [App] on an unenrolled device and is assigned an account that falls under CA Policy 1 and 2, however [App] is excluded from 1 and shouldn't apply to this login. When accessing [App] for the first time, users must register SSPR/MFA. They see the below message, click 'Next' and are directed tohttps://accounts.activedirectory.windowsazure.com/passwordreset/register.aspx: Then they see this screen, which will block the login and try to get the user to download the Company Portal app: While behind the scenes, the login to [App] is being blocked by 'Microsoft App Access Panel' because it is seemingly added to the login flow and caught in CA Policy 1 in Req 2/3: CA Policy 1 shows as not applied on Req 1, CA Policy 2 shows as successful for Req 1/2/3 and CA Policy 3 shows as not applied for Req 1/2/3. Creating a CA policy for the 'Register security information' user action has no effect on this scenario and also shows as not applied on all the related sign-in logs. ----Example 2---- Environment: Same as above, but SSPR registration enforcement - set to 'No' Scenario: Same as above, but when accessing the [App] for the first time, they see the below message instead, click 'Next' and are directed to https://accounts.activedirectory.windowsazure.com/proofup.aspx: Then they are directed to the combined SSPR/MFA registration experience successfully: The 'Microsoft App Access Panel' doesn't show in the sign-in logs and the sign-in is successful after registration. From the two examples, it seems to be a bug with the SSPR registration enforcement and the combined registration experience. ----Workarounds---- 1 - Prevent using 'All cloud apps' with device based CA policies (difficult, requires redesigning/thinking/testing policies, could introduce new gaps, etc) 2 - Turn off SSPR registration enforcement and turn on MFA registration enforcement like in example 2 (easy, but only enforces MS MFA App registration, doesn't seem to re-trigger registration if the MS MFA App is removed, no other methods are supported for registration, and doesn't remind users to update) 3 - Disable SSPR entirely for affected users (medium depending on available security groups, and doesn't allow for affected users to use SSPR) ----Related links---- Be able to exclude Microsoft App Access Panel from Conditional Access · Community (azure.com) Support conditional access for MyApps.microsoft.com · Community (azure.com) Conditional Access Policies, Guest Access and the "Microsoft Invitation Acceptance Portal" - Microsoft Community Hub MS, please either: 1 - Allow 'Microsoft App Access Panel' to be added to CA policies so it can be excluded 2 - Prevent 'Microsoft App Access Panel' from showing up in the CA login flow when SSPR registration enforcement is enabledPasswordless app notification not pushing into iOS notifications (app must be opened manually)
When switching to passwordless authentication, the Microsoft authenticator app does not generate a push notification in the iOS notification center. When I open the Microsoft authenticator app, the number matching prompt is displayed, so the sign-in works as expected, but I don't get a push notification from the app. The strange thing is, when I disable the passwordless method, and fallback to password + push notification with number matching, then the Microsoft authenticator generates the push notification in the iOS notification center. How could I troubleshoot that issue?
Exception in conditional access policy for "Windows app - macOS"
Hi, I'm trying to restrict all Enterprise resources to Cloud-PC's only and therefore have a CAP in place that restricts access to all apps to cloud-pc's only. Naturally I have to provide an exception for the Remote desktop app so that end users can connect from their private endpoints to the cloud-PC. Here's the problem though. While I can find an exception for the Windows Remote Desktop app this exception doesn't apply to macOS and when looking at the sign-in logs the policy locks out "Windows App - macOS" with the app-id63896e48-3d27-4ce2-9968-610b4af62c5d. Neither "Windows App - macOS" nor63896e48-3d27-4ce2-9968-610b4af62c5d is findable in the application list for CAP exceptions. Is there a workaround or will this be made available? Maxim
Guest accounts and MFA via Conditional Access in MS Entra
Hi experts, trying to get some help on my scenario and issue that external users started to experience since I've enabled MFA for external identities & guest users via Conditional Access. We have lots of external partners that we share some documentation with from our SharePoint. Some time ago, I have enabled "MS Entra B2B Integration for SharePoint and OneDrive" so that any external user that access shared files/folders in our SharePoint gets a GUEST account created in our tenant. This was also preparation for enabling MFA for External users via Conditional Access. I believe these are called "B2B Collaboration guests" Now, few days ago, I have enabled MFA via Conditional Access for all external users and guests, enabled for all cloud apps and require MFA to grant access. Until now, I got feedback from two external partners that their existing access doesnt work anymore - and they need to go through MFA (which is expected). The problem is that when they go through MFA set up, it ends up in a "loop" - meaning, they go through all steps but when completing the last step they are returned back to the very 1st step again. So they: scan QR code successfully authenticate get the page that it was successful get back to the 1st step asking to install or use MS Auth app The user tried different browsers also with Incognito tabs... When I am checking sing-in logs: guest account is created fine the status is: "Interrupted" additional details: The user was presented options to provide contact options so that they can do MFA. conditional access forcing MFA is marked as FAILED as MFA was not completed Both external partners that reported this are using MS Entra and I see their IDENTITY as ExternalAzureAD. Have not heard back from anyone else using other than ExternalAzureAD so not sure if there is something extra that needs to be configured. Anyone experienced this issue? Any idea what can be wrong? I do not have any cross-tenant collaboration etc configured...
Failed authentication with SAML Certificate
When I create a new Enterprise application, and I set up SAML-based SSO. The token signing certificate (Base64) I get fails to login my user into my application. I have to re-upload the certificate for successful login request. This has started happening often.User and Permissions Management Issues in Microsoft Entra ID (Assigned Roles)
Hello everyone, I’m encountering some challenges with user and permission management in Microsoft Entra ID. Here are the main issues I'm facing: Revoking Local Administrator Permissions: After removing a user from the Local Device Administrator group in Microsoft Entra, the device continues to recognize the user as an administrator, even after multiple synchronization attempts. What’s the recommended procedure to force a permissions update on the associated devices? Device Join Issue via PowerShell: I'm trying to join a device to Microsoft Entra ID using PowerShell with the command dsregcmd /join to force a policy update, but I'm encountering the following error: Error 0x80041326: "Failed to schedule Join Task. Error: 0x80041326." Does anyone know how to resolve this issue or have suggestions for an alternative approach to join the device or enforce the policy? I’ve checked permissions and task scheduling services, but the problem persists. Has anyone experienced similar issues or have suggestions on how to address these challenges? Any advice would be greatly appreciated! Thanks so much in advance!
