Looking for an on-prem MFA solution for Active Directory and RDP
Hi everyone, We're reviewing options for adding MFA to our on-premises Active Directory environment. Most of our users authenticate with Active Directory, while administrators also use RDP for managing Windows servers. Because part of our infrastructure is isolated from the Internet, we'd prefer an on-premises MFA solution instead of relying on a cloud-only service. Has anyone implemented something similar recently? I'm interested in hearing: Which solution did you choose? How difficult was the deployment? Did you run into any compatibility or performance issues? Is there anything you'd do differently if you were deploying it again? Any real-world experience or recommendations would be greatly appreciated. Thanks!
MFA Options for Employees without Phones
Hello everbody, we're currently trying to implement MFA in our company, but approximately 1/10 of our employees have a workphone and are not allowed to use their personal phone. Since we also recently introduced Intune, the idea was to just use Windows Hello for Business, but when trying to provision it, we realized that you need to have MFA active for an account to be able to even activate it? Which kinda defeats the purpose. So my question is, is there some way to circumvent the MFA requirement for WHfB? Or what other options do we realistically have? Thanks in Advance!
Introducing the Entra Helpdesk Portal: A Zero-Trust, Dockerized ITSM Interface for Tier 1 Support
Hello everyone, If you manage identity in Microsoft Entra ID at an enterprise scale, you know the struggle: delegating day-to-day operational tasks (like password resets, session revocations, and MFA management) to Tier 1 and Tier 2 support staff is inherently risky. The native Azure/Entra portal is incredibly powerful, but it’s complex and lacks mandatory ITSM enforcement. Giving a helpdesk technician the "Helpdesk Administrator" role grants them access to a portal where a single misclick can cause a major headache. To solve this, I’ve developed the Entra Helpdesk Portal (Community Edition)—an open-source, containerized application designed to act as an isolated "airlock" between your support team and your Entra ID tenant. Why This Adds Value to Your Tenant Instead of having technicians log into the Azure portal, they log into this clean, Material Design web interface. It leverages a backend Service Principal (using MSAL and the Graph API) to execute commands on their behalf. Strict Zero Trust: Logging in via Microsoft SSO isn’t enough. The app intercepts the token and checks the user’s UPN against a hardcoded ALLOWED_ADMINS whitelist in your Docker environment file. Mandatory ITSM Ticketing: You cannot enforce ticketing in the native Azure Portal. In this app, every write action prompts a modal requiring a valid ticket number (e.g., INC-123456). Local Audit Logging: All actions, along with the actor, timestamp, and ticket number, are written to an immutable local SQLite database (audit.db) inside the container volume. Performance: Heavy Graph API reads are cached in-memory with a Time-To-Live (TTL) and smart invalidation. Searching for users or loading Enterprise Apps takes milliseconds. What Can It Do? Identity Lifecycle: Create users, auto-generate secure 16-character passwords, revoke sign-in sessions, reset passwords, and delete specific MFA methods to force re-registration. Diagnostics: View a user's last 5 sign-in logs, translating Microsoft error codes into plain English. Group Management: Add/remove members to Security and M365 groups. App/SPN Management: Lazy-load raw requiredResourceAccess Graph API payloads to audit app permissions, and instantly rotate client secrets. Universal Restore: Paste the Object ID of any soft-deleted item into the Recycle Bin tab to instantly resurrect it. How Easy Is It to Setup? I wanted this to be universally deployable, so I compiled it as a multi-architecture Docker image (linux/amd64 and linux/arm64). It will run on a massive Windows Server or a simple Raspberry Pi. Setup takes less than 5 minutes: Create an App Registration in Entra ID and grant it the necessary Graph API Application Permissions (e.g., User.ReadWrite.All, AuditLog.Read.All). Create a docker-compose.yml file. Define your feature toggles. You can literally turn off features (like User Deletion) by setting an environment variable to false. version: '3.8' services: helpdesk-portal: image: jahmed22/entra-helpdesk:latest container_name: entra_helpdesk restart: unless-stopped ports: - "8000:8000" environment: # CORE IDENTITY - TENANT_ID=your_tenant_id_here - CLIENT_ID=your_client_id_here - CLIENT_SECRET=your_client_secret_here - BASE_URL=https://entradesk.jahmed.cloud - ALLOWED_ADMINS=email address removed for privacy reasons # CUSTOMIZATION & FEATURE FLAGS - APP_NAME=Entra Help Desk - ENABLE_PASSWORD_RESET=true - ENABLE_MFA_MANAGEMENT=true - ENABLE_USER_DELETION=false - ENABLE_GROUP_MANAGEMENT=true - ENABLE_APP_MANAGEMENT=true volumes: - entra_helpdesk_data:/app/static/uploads - entra_helpdesk_db:/app volumes: entra_helpdesk_data: entra_helpdesk_db: 4.Run docker compose up -d and you are done! I built this to give back to the community and help secure our Tier 1 operations.

Hi, We are experiencing a catch-22 scenario during user onboarding related to MFA. New users are required to install the Microsoft Authenticator app via our Company Portal. However, they are prompted to complete MFA registration before they can access or download anything from the Company Portal. Since they do not yet have the Authenticator app installed, they are effectively blocked from completing the MFA setup. From our investigation, it appears that the Multi-Factor Authentication registration policy is enforcing MFA registration for new users. In our scenario, this creates a circular dependency. We have attempted to exclude our office network from MFA using Conditional Access, but this does not resolve the issue because the MFA registration policy is triggered before Conditional Access policies are evaluated. Our questions: Is there a recommended way to handle MFA onboarding in this type of scenario? Can Conditional Access policies be used instead of the MFA registration policy for initial MFA enrollment?
NPS Extension for azure MFA and multiple tenants?
Hi, is it possible to setup one NPS server with the Extension for Azure MFA to authenticate against multiple tenants? The onprem AD has azure ad connector for each domain and the users are in sync with there tenants. Its a RDS setup with one RD Gateway and one NPS server and multiple RD servers. I need email address removed for privacy reasons and email address removed for privacy reasons etc. to authenticate with MFA, but i can only get the users on the tenant thats linked in the NPS Extension for Azure MFA to work. I dont think its possible to setup more than one tenant in one NPS server (Extension for azure MFA). I get this error in the NPS log NPS Extension for Azure MFA: CID:xxxxxxxxxxxxxxx : Access Rejected for user email address removed for privacy reasons with Azure MFA response: AccessDenied and message: Caller tenant:'xxxxxxxxxxxxxxxxxxxxxxx' does not have access permissions to do authentication for the user in tenant:'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',,,xxxxxxxxxxxxxxxxxxxxxx The ID in the Caller tenant and the user tenant in the error is correct, so something have to work? I cat find a way to allow the Caller tenant to access users in the user tenant.
Disabling PIN-based login on Entra-joined PCs
Hi guys. Yesterday I took two machines off the domain and Entra joined them. The goal was 1) remove their access to domain resources 2) have tenant users login to the machine and get enriched tokens every time. this works as desired. The problem is every user gets prompted to set a pin. these are both shared secondary/tertiary PC's - there is no point to having a 6 digit PIN on them. I thought the new Authentication Methods tools had controls for this, but apparently not. A script was run to change certain related Reg Keys (by my onsite tech) but this had no change on reboot. textreg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork" /v Enabled /t REG_DWORD /d 0 /freg add "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork" /v DisablePostLogonProvisioning /t REG_DWORD /d 1 /f HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\PassportForWork Enabled key was set to 0, and DisablePostLogonProvisioning was set to 1. These are from various help threads I found here and other resources. Unfortunately, they do not work. Not sure what to do here. I've read there are InTune controls for this - but I don't really have the time to work out WindowsPC ennrollment profiles for 2 machines. The site has InTune, but only for iOS mobile management.

{ "error": "access_denied", "error_description": "AADSTS55203: Configuring multi-factor authentication method is blocked. Trace ID: Correlation ID: Timestamp: 2025-09-17 20:48:30Z", "error_codes": [ 55203 ], "timestamp": "2025-09-17 20:48:30Z", "trace_id": "", "correlation_id": "", "suberror": "provider_blocked_by_rep" } SMS authentication method was previously configured in our B2C Entra and was functioning correctly until last week, when it suddenly stopped working. Currently, users can only authenticate via email. Conditional Access policy is also in place that requires Multi-Factor Authentication (MFA).Grant Just-in-Time Admin Access with Microsoft Entra PIM
In my lab, I worked with Microsoft Entra Privileged Identity Management (PIM) to grant Just-in-Time admin access. Instead of permanent assignments, users become eligible for roles and must activate them only when needed. Steps I tested: - Configured roles as eligible rather than permanent - Required MFA and approval for role activation - Verified access automatically expired after the time window This approach reduces standing privileges and aligns with Zero Trust by securing privileged access. Curious — does your org still keep permanent Global Admins, or have you moved to JIT with PIM?
Entra External Authentication Method giving AADSTS900144 missing externalAuthenticationMethodId
Hi All, Has anyone else noticed in the last couple of days if EAM (External Authentication Method) is configured for MFA end users are getting: AADSTS900144: The request body must contain the following parameter: 'externalAuthenticationMethodId' Its been working for us fine for months/years but the last couple of days we are seeing heaps of the error above. I have raised a support case but zero response so far Regards, Daniel
