Azure AD Connect
164 TopicsDo the Entra sync/connect apps ever successfully update themselves?
Last week I had to download and install version 2.5.79.0 of the Entra Connect Sync Agent app on our Entra Connect server because I discovered the installed version was 2.4.21.0 and that version reaches end of support on November 15. Today, I happened to check on the version of the Entra Private Network Connector app on the two servers where we have that installed, and both are running version 1.5.3925.0, which was the latest available version at the time I installed it back in March. That version was from July 2024, and there have been three new releases since then, two of which "may perform auto-update of your connector". One of those servers was a new install, but the other one was an upgrade of the installed version of the Azure Application Proxy client, and while I don't recall which version specifically was installed, I know it was quite out of date. I'm curious: Has anyone ever actually seen either the Entra Connect Sync Agent or Entra Private Network Connector successfully upgrade themselves automatically?Solved42Views1like1CommentMicrosoft Entra Connect sync stopped, request upgrade and library not found
Hello, I have the latest (for our company, present on Entra blade) version of Microsoft Entra Connect Sync: 4 days ago I noticed on Synchronization Service Manager that there is no sync of data; I have started the Microsoft Entra Connect Sync and found a big button with "Upgrade" word; I tried to execute the upgrade but when the it arrives to the Connect to Microsoft Entra ID step, I fill with my global administrator account but found a stop error: An error occured while retrieving the Active Directory schema. The error was: Could not load file or assembly 'file:///C:\Program Files\Microsoft Azure AD Sync\Bin\Microsoft.IdentityModel.Clients.ActiveDirectory.dll' or one of its dependencies. The system cannot find the file specified. and when I click again on Next I have the same request of global administrator user and password and the same error. Now, the library is not present but I verified, in a test tenant where I have a working Entra Connect Sync system, that the files is not present even there (and also when I start Microsoft Connect Entra Sync I haven't the upgrade button there); I also tried to repair the installation, but obviously the file is no there. What can I do? Are there other people with the same issue? Any idea is appreciated.146Views0likes3CommentsAzure AD Health Failing
I am on the latest version of Azure AD Connect (2.5.79.0)... There are no network/DNS/connectivity issues at our site, it seems to me that Azure AD Health Service is having trouble because the endpoint is experiencing a service issue.. Is anyone else having the same problem with failure alerts/etc? I checked by running "Test-MicrosoftEntraConnectHealthConnectivity -Role SYNC" command, the stack trace throws an undocumented error number and complains of rate limiting issues... smells like the server is being overwhelmed or there are other issues slowing down the endpoint/service with the consequence that connections are piling up causing this error: Connectivity Test Step 1 of 2: Testing dependent service endpoints begins ...

We have configured API-driven provisioning for on-premises Active Directory, along with Azure AD Connect, to synchronize on-premises AD users with Azure Entra ID. As part of the provisioning setup, we have used a separate Organizational Unit (OU) in on-premises AD (designated as the default OU for new users) while configuring API-driven provisioning. We are attempting to make some changes to the API field mapping, specifically the ‘UserPrincipalName’ regular expression (custom domain) and the ‘manager’ field, and saving the configuration. Upon attempting to save, a prompt appears (as highlighted below screenshot), indicating that this action will resynchronize all users and groups. Could you please clarify: Will this resynchronization update any existing users outside the default provisioning Organizational Unit (OU)? Specifically, what does the resynchronization operation update? For instance, will it modify the 'UserPrincipalName' and 'manager' attributes for all users including old users outside of provisioning Organizational Unit (OU)?

We are planning on demoting old DC server. When doing checkups I noticed that Entra Connect keeps connecting to this specific DC we'ew planning to demote everytime it connect to Active Directory. So now I'm wondering does this need any additional configuration to keep sync working after DC Demote. I found out that there is option to "Only use preferred domain controllers" but I'm not sure if that's what I want do do. There were the red line is is the old DC to be demoted. "Only use preferred domain controllers" setting. If I enable this setting I got this kind of notice. I don't feel like this is the right way to do it so I canceled at this point.Solved133Views0likes2CommentsMy Azure login is stuck at MFA and cannot proceed
In August, I was still able to log in to Azure, and by logging in through GitHub I could bypass 2FA. But now, no matter how I try, logging in via GitHub always requires 2FA. I can’t access my Azure account anymore—nothing works. The system prompts me to use Microsoft Authenticator to confirm a two-digit code in real time. My Microsoft Authenticator on my iPhone is logged into the same Microsoft account, but I’m not receiving any verification requests for Azure login. No matter how much I refresh, nothing shows up. I’ve already updated the Microsoft Authenticator app to the latest version from the App Store. However, my personal Microsoft account works fine and can log in without any issues.124Views0likes1CommentThe salt sizes required for signing with RSAPSS do not match those used by TPM.
Good evening everyone. I'm getting this error when I try to perform the first sync on my Windows Server 2022. I'm trying to sync the entire directory to manage my employees' licenses. I already have a tenant with users who can stay there without any problems. I had already synced the tenant with my old server in the past. For business reasons, the infrastructure has changed, and so has the server. In Entra ID, I don't see any old syncs, but in Admin Center, I do. Could this be the problem? Any advice is invaluable, as I'm at my wits' end.171Views0likes2CommentsOU list incomplete in AAD connect
We're facing a strange issue while configuring EntraID Connect. At the point of selecting the OU we want to synchronize the list we see in the EntraID application is not complete in respect of what we see in ADUC. We miss an OU at first level, which by the way is ont of the OU we need to sync. Any idea ?Solved144Views0likes4CommentsUser Identities in EntraID - how to remove?
I have a user that shows up with multiple identities. No other users are like this and we believe its stopping him from logging in with his alias email address. When i run get-entrauser it returns the following under Identities: {@{signInType=federated; issuer=MicrosoftAccount; issuerAssignedId=}, @{signInType=federated; issuer=MicrosoftAccount; issuerAssignedId=}, @{signInType=userPrincipalName; issuer=OURPRIMARYDOMAIN.onmicrosoft.com; issuerAssignedId=UPN}} Every other account just has this @{signInType=userPrincipalName; issuer=OURPRIMARYDOMAIN.onmicrosoft.com; issuerAssignedId=UPN}} How would i go about removing those identies from that user? Struggling to find any info online.114Views0likes1Comment
