Password Expiration notification
I have a number of users who have recently transitioned to Azure joined devices and are authenticating directly through AAD, though their accounts were originated in On-prem AD. When their passwords expire, they aren't getting notification but finding out when certain on-prem services aren't connecting. We are using AD Sync and it's going both ways AAD to OP and OP to AAD . I guess my question is 2 fold: Is it possible that AD is still expiring the password and if not, where can I find where it is expiring? Is there any way to turn on expiration notification for Azure AD users? Thanks,Active Directory Vs Azure Active Directory
Active Directory (AD) and Azure Active Directory (AAD) are both identity management solutions from Microsoft, but they serve different purposes. In this blog post, we’ll explore the differences between AD and AAD and when you might want to use one over the other. Active Directory (AD) Active Directory is a service provided by Microsoft that is used to manage users, computers, and other resources in a Windows-based network. It was first introduced in Windows 2000 and has since evolved into the core identity management solution for most organizations that use Windows-based systems. AD is a domain-based directory service, which means that it is designed to work within a single organization’s network. AD stores user and computer account information, authentication and authorization data, and security policies. It also provides services such as Group Policy, which allows administrators to configure and enforce policies for users and computers in the domain. AD is typically deployed on-premises and requires a domain controller to operate. Domain controllers are servers that store and manage AD data and provide authentication and authorization services to users and computers in the domain. Azure Active Directory (AAD) Azure Active Directory is a cloud-based identity management solution that is used to manage users and groups, control access to cloud-based applications, and integrate with other cloud-based services. It is a multi-tenant directory service, which means that it can be used by multiple organizations at the same time. AAD provides many of the same features as AD, such as user and group management, authentication and authorization, and security policies. However, AAD is designed to work with cloud-based applications and services, and it does not require a domain controller. AAD is often used in conjunction with other cloud-based services, such as Office 365, Azure, and other SaaS applications. AAD provides a single sign-on (SSO) experience for users, which means that users only need to log in once to access all of the cloud-based applications and services that they have access to. When to use AD vs AAD AD is still the go-to solution for managing identity and access in on-premises Windows-based networks. If you are running a Windows-based network and you need to manage users, computers, and other resources within your organization, then AD is the right choice. AAD is best suited for organizations that are using cloud-based services and applications. If you are using Office 365 or other cloud-based services and you need to manage users and control access to those services, then AAD is the right choice. It is also possible to use both AD and AAD in a hybrid environment. In this scenario, AD is used to manage on-premises resources, while AAD is used to manage cloud-based resources. This allows organizations to maintain a consistent identity and access management strategy across their on-premises and cloud-based environments. Active Directory and Azure Active Directory are both powerful identity management solutions, but they serve different purposes. AD is designed for on-premises Windows-based networks, while AAD is designed for cloud-based services and applications. Depending on your organization’s needs, you may choose to use one or the other, or a combination of both in a hybrid environment.
Resolution of Active Directory Replication Error 8606 &1988
Scenario DC is Virtualized in VMware, I got it restored from Veeam backup, meaning it is not in the current state, that caused https://bit.ly/3tHlhlE Broken, how could I get it fixed? I forced replication between 2 DCs it failed. Here and there we got several PCs that have the error: “The trust relationship between this Workstation and the primary Domain failed” Based on above use case, identified certain errors. Investigation So first, a piece of advice that, you should never restore a domain controller in a multi-domain controller environment. Instead, you should stand up a new DC and start replication, it will take time but will replicate from a fully healthy DC. Then we ran the below command-lets and collected the logs for review. Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log repadmin /showrepl >C:\repl.txt ipconfig /all > C:\dc1.txt ipconfig /all > C:\dc2.txt ipconfig /all > C:\problemworkstation.txt Errors Observed in DC Diagnostic Report & Replication Summary We found following two errors in DC diagnostic report and Replication summary : Active Directory Replication Error 8606: Insufficient attributes were given to create an object. Active Directory Replication Error 1988: The local domain controller has attempted to replicate the following object from the following source domain controller. This object is not present on the local domain controller because it may have been deleted and already garbage collected. Logging Conditions for Error 8606 Upon further research, we found out that Error 8606 is logged when the following conditions are true: A source domain controller sends an update to an object (instead of an originating object create) that has already been created, deleted, and then reclaimed by garbage collection from a destination domain controller's copy of Active Directory. The destination domain controller was configured to run in strict replication consistency. Cause of Error 8606 The error is caused by one of the following: A permanently lingering object whose removal will require admin intervention. A transient lingering object that will correct itself when the source domain controller performs its next garbage-collection cleanup. Introduction of the first domain controller in an existing forest and updates to the partial attribute set are known causes of this condition. An object that was undeleted or restored at the cusp of tombstone lifetime expiration. Key Points to Remember for Troubleshooting Error 8606 When you troubleshoot 8606 errors, think about the following points: Although error 8606 is logged on the destination domain controller, the problem object that is blocking replication resides on the source domain controller. Additionally, the source domain controller or a transitive replication partner of the source domain controller potentially did not inbound-replicate knowledge of a deleted tombstone lifetime number of days in the past. Remember to search for potentially lingering objects by object GUID versus DN path so that objects can be found regardless of their host partition and parent container. Searching by objectguid will also locate objects that are in the deleted objects container without using the deleted objects LDAP control. The NTDS Replication 1988 event identifies only the current object on the source domain controller that is blocking incoming replication by a strict mode destination domain controller. There are likely additional objects "behind" the object that is referenced in the 1988 event that is also lingering. The presence of lingering https://bit.ly/3CdDCd2 prevents or blocks strict mode destination domain controllers from inbound replicating "good" changes that exist behind the lingering object in the replication queue. Because of the way that domain controllers individually delete objects from their deleted object containers (the garbage-collection daemon runs every 12 hours from the last time each domain controller last started), the objects that are causing 8606 errors on destination domain controllers could be subject to removal in the next garbage-collection cleanup execution. Lingering objects in this class are transient and should remove themselves in no more than 12 hours from problem start. The lingering object in question is likely one that was intentionally deleted by an administrator or application. Factor this into your resolution plan, and beware of reanimating objects, especially security principals that were intentionally deleted. Resolution Resolution For our need, to check the replication status in between only 2 DCs (The affected one and a healthy one), we have also tried disabling “Strict Replication Consistency” that prevents destination domain controllers from replicating in lingering objects, but it is highly recommended not to disable “Strict Replication Consistency”, there can be a risk that lingering objects could be replicated to a domain controller or many where this setting is not enabled. Reference Microsoft Documentation for enabling this setting: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2008-R2-and-2008/cc816938(v=ws.10)?redirectedfrom=MSDN As an actual fix, we must have to remove the lingering objects from the recovered DC for the smooth replication. While many methods exist to remove lingering objects, there are two primary tools commonly used: Lingering Object Liquidator (LoL) and repadmin.exe. Lingering Object Liquidator (LoL) The easiest method to clean up Lingering Objects is to use the LoL. The LoL tool was developed to help automate the cleanup process against an Active Directory Forest. The tool is GUI-based and can scan the current Active Directory Forest and detect and cleanup lingering objects. The tool is available on https://www.microsoft.com/en-us/download/details.aspx?id=56051. Repadmin.Exe The following command in REPADMIN.EXE can remove lingering objects from directory partitions: Repadmin.Exe /RemoveLingeringObjects Repadmin / RemoveLingeringObjects can be used to remove lingering objects from writable and read-only directory partitions on source domain controllers. The syntax is as follows: c:\>repadmin /removelingeringobjects <Dest_DSA_LIST> <Source DSA GUID> <NC> [/ADVISORY_MODE] Where: <Dest_DSA_LIST> is the name of a domain controller that contains lingering objects (such as the source domain controller that is cited in the NTDS Replication 1988 event). <Source DSA GUID> is the name of a domain controller that hosts a writable copy of the directory partition that contains lingering objects to which the domain controller in <Dest_DSA_LIST> has network connectivity. The DC to be cleaned up (first DC specified in the command) must be able to connect directly to port 389 on the DC that hosts a writable copy of the directory partition (specified second in the command). <NC> is the DN path of the directory partition that is suspected of containing lingering objects, such as the partition that is specified in a 1988 event. Monitoring Active Directory Replication Health Daily If error 8606 / Event 1988 was caused by the domain controller's failing to replicate Active Directory changes in the last tombstone lifetime number of days, make sure that Active Directory replication health is being monitored on a day-to-day basis going forward. Replication health may be monitored by using a dedicated monitoring application or by viewing the output from the one inexpensive but effective option to run "repadmin /showrepl * /csv" command in a spreadsheet application such as Microsoft Excel. Thus, keeping tabs on Active Directory Health overall is significant. In order to do that, its important for an IT Professional to have an understanding of https://bit.ly/3EjPtYX?
Windows server 2025 Forest and Domain functional levels.
As many will no doubt have noticed, there is a 2025 forest and domain functional level introduced in build 25941. The schema updates suggest these are delegated managed service accounts (dMSA) and 32k pagesize for the active directory database. Is there any documentation on these?
Migrate on-prem AD to azure AD having ADDS
I have to move legacy apps from on-prem to azure. What I read is to use ADDS for legacy apps authentication is the only option since some of my legacy apps are using SSO and some has service accounts at on-prem AD. the goals are below: Migrate on-prem active directory to azure active directory and have azure active directory domain services. Migrate local group policies to azure active directory domain services migrate all services accounts from azure managed identities so those can be used on legacy applications. Migrate all user profiles seamlessly. Completely demote on-prem active directory. The environment is having 956 users and 20+ applications. currently have on-prem AD and azure AD and users are hybrid joined. Please guide through the process and best practice for above scenario.
PIM License requirement
Hello Team, I have a doubt regarding Azure AD PIM Licensing. According to the documentation: "Licenses you must have Ensure that your directory has at least as many Azure AD Premium P2 licenses as you have employees that will be performing the following tasks: Users assigned as eligible to Azure AD or Azure roles managed using PIM Users who are assigned as eligible members or owners of privileged access groups Users able to approve or reject activation requests in PIM Users assigned to an access review Users who perform access reviews " In my tenant, The Azure AD P2 (Microsoft Entra ID P2) license is assigned at the tenant level. Now my question is - 1. I have 30 users that will be added to some privileged role and will be managed via PIM. In My tenant I have 40 E5 licenses. Do 30 Azure AD E5(P2 will get automatically provisioned) licenses need to be assigned to these individual 30 users who will be in scope of PIM? or no need to assign as the tenant has already Azure AD P2 license activated at tenant level. 2. If I do not assign the license to the users individually, will I breach any compliance policy from Microsoft? Please help me here.
