Does Azure AD has a mechanism to detect if the target system is down during SCIM synch? For example a user is added to AD and this user has to be provisioned to some other target system that also supports SCIM, however the target system is down due to whatever reason. Can Azure AD detects once the target system is up so the changes can be synched with the target system?
They will be marked as process escrow and it will retry exporting later:
https://learn.microsoft.com/en-us/azure/active-directory/manage-apps/check-status-user-account-provisioning
Process escrow events - Process escrows occur when the provisioning service encounters a failure while attempting an operation, and begins to retry the operation on a back-off interval of time. An "escrow" event is recorded each time a provisioning operation was retired.
Azure AD will postpone the sync for some time and retry. For this reason it's mandatory to check the Audit Logs once in a while to make sure to detect and correct errors.

Looking for any documentation or reference for Azure AD Conditional Access Audit\Sign-In Logs. For example, i'd like to generate a report of all users who have been blocked due to a defined Conditional Access Policy.
It seems that events (such as blocking users through policy) do not appear in the Azure Active Directory Sign-In or Audit logs. Are these events recorded anywhere within OMS \ Azure Reporting?
If you go to Sign-ins logs, you can see a dropdown for Conditional Access where you can check if users are blocked.
In a multi-domain-setting, I want to collect security file access audit events at a central place.
In ActiveDirectory, it is possible to enable file access auditing at the Domain Controller by creating a GPO.
Additionally, at a different 'file server' computer, that is a member of one of the domains, a SACL has to be configured at the file system objects that I want to be audited (and that are included in a network share).
Once this is done, the file access events are recorded and somehow magically transfered to the event log of the domain controller.
I would really like to know:
How and when are these events transfered? Is the transfer
encrypted?
Is it possible to directly select another (additional) receiver of those events, apart from the domain controller? I know that it is possible to forward those log events later on, but are they by default forwarded to the Domain Controller? Is there an implicit forwarding configured?
How much traffic is going to be generated, with respect to network load?
First thing domain controller is server having Active Directory(a kind of organisation database). Active directory identified every component/resources connected into domain whether logical(user) and physical(computer and printer) as a object. This object has properties known as Schema. This schema has been catalog in repositories known as GC(Global catalogue) but gc has only partial information so that resources can be located.
Now, coming to this policies. There is two thing GPO and OU. GPO is set of policies that you can apply on OU or higher grouping unit.
Let's see how communication happen. Again, there is two widely used term 1. replication and 2. LDAP Query.
Replication is done between controller so that network traffic can be reduced and for higher availability for resources connected to server. In replication, all resource information has synchronized with server. To ensure security integrity, there is certificate(which gives identification as well encryption mechanism) and delegation(providing rights).
LDAP is protocol through which user has been authenticated. So LDAP has query which quiet similar to other query language. Well all this query has been logged ultimately to server.
GPO has been replicated on resources or you can apply forcibly. If you want to do it immediately.
I create a service which is defined to Log On as Administrator.
This service performs system("net use Z: \... /user:user password") and completes successfully.
If I (as Administrator) run "net use" I see Z: indeed added, but with status - unavailable.
I tried adding ImpersonateLoggedOnUser to the service, but that didn't help.
OS: Win XP
What am I missing?
ImpersonateLoggedOnUser doesn't impersonate the logon session from the user token, just the security context. CreateProcessAsUser, however, should be able to create a new process in the logon session associated with the specified user token.
Note that calling LogonUser to get a user token for CreateProcessAsUser won't work, because this token won't be in the same logon session as the logged-on user. You have to find one of the user's processes and duplicate its token.
Logon sessions are not well documented, but all you really need to know that each time a user is authenticated a distinct logon session is created, and that each such logon session has a distinct set of network drive mappings. Logon sessions are not the same as terminal services sessions.
In Windows Vista and above, two logon sessions are created when an administrative user logs in, one associated with the restricted token and one associated with the elevated token.
You can look up the logon session associated with a token using the GetTokenInformation function with the TokenStatistics option. The logon session is identified by the AuthenticationId LUID.
To make this work, your service would need to first figure out when a user has logged in, wait for a process associated with the new session to start, make sure it's not an elevated process, then duplicate the access token.
Instead, your best option is going to be to split the application into two components. One component will run as the user (you would probably launch this automatically using the Run key) and be responsible for mapping the network drive. It can contact the service to obtain any information it needs, either via a named pipe or a registry key.
Windows logs on Administrator and uses the logon token to start the service. If you logon interactively Windows creates a logon token for you. The two tokens are not related to each other. Mapped devices are mapped for one session/logon token, therefore if the service maps a device you do not see it in your logon session.
We have a system using two machines to do some processing. Let's call the machine that does the processing PROCESSOR, and the machine giving it items to process SERVER. Both are running Windows Server 2008. We have one Windows Service running on SERVER which needs to use MSMQ to send messages to a public queue PROCESSOR.
On PROCESSOR, we have another Windows Service which pulls items from the queue for processing.
The two machines are in the same domain, and all works fine if we run both services under accounts with domain admin privileges. However, we need the accounts to have the minimum privileges possible (particularly for the service on SERVER).
Before elevating the rights of the account we're using for the service on PROCESSOR, I tried giving it full rights to MSMQ. However, this didn't seem to be enough, and as soon as the service tried to do anything with MSMQ (first thing it does on starting is to check if relevant queues exist), I got an exception saying "Access to Message Queuing is denied".
Does anybody know what permissions need to be granted to an AD account in order for it to be able to use MSMQ?
Thanks,
Andrew
Run your service under a defined system account, like (I believe Network), then set the permissions on the MSMQ to full control for that.
When I've used this in the past I just cheated and allowed access to "Everyone". But in a domain setting the best way is to create a domain user and set that for the service and permissions on the MQ.
You need to set permissions on the objects in Active Directory.
So you'll need Get Properties permission if you are querying objects, for example.
This should be on the MSMQ object under the computer object and the queue object(s) under the MSMQ object.
Also, the defaults are going to be restricted to allowing everyone to send but not receive so you will need to add that access for the domain account you are using to be able to read messages.
We use merge replication in one of our programs and I would like to allow our users to force synchronization of their laptops with the publisher on an as-needed basis (we are using push subscriptions). I got this working using REPLMERG.EXE (see my previous question).
However, when the users trid to run the script they received the following error message:
Only members of the sysadmin or db_owner roles can perform this operation.
...
exec sp_MSreplcheck_subscribe
...
If I add the users' group login as a db_owner on their local subscription database then the script works correctly. The problem is that they also end up with full access to every table in their local database, which is not something we can live with.
Allowing users in a merge replication topology to synchronize their local push subscriptions on-demand without giving them full-blown control of the db seems like a pretty straightforward use case, but I can't get it working.
From Replication Agent Security Model:
Merge Agent for a pull subscription
The Windows account under which the
agent runs is used when it makes
connections to the Subscriber. This
account must at minimum be a member of the db_owner fixed database role in
the subscription database.
The account that is used to connect to the Publisher and Distributor must:
Be a member of the PAL.
Be a login associated with a user in the publication database.
Be a login associated with a user in the distribution database. The
user can be the Guest user.
Have read permissions on the snapshot share.
Therefore is a documented requirement of Merge replication that the account running the replication agent (replmerge.exe) be member of db_owner. If you this does not work for you situation, then Merge replication is not the right technology to use, since it has a requirement you cannot fill.
Now int theory an application can do whatever REPLMERGE does from another application, and you can leverage the power of code signing to run a set of wrapper procedures that are granted dbo privileges via code signing, thus not needing the elevated login, but that's just theory since the replication procedures are not exactly easy to use nor are they documented at the level one needs to re-implement the agents...
The suscriber must have the right to replicate data definition instructions sent on the publisher. Some of these instructions might even lead to the reinitialisation of the subscriber, which requires the right to a drop\recreate the corresponding database. In these conditions, security requirements as set by Microsoft sound quite sensible.
As Remus and Philippe have pointed out, db_owner on the subscription db is a hard requirement for synchronizing a merge push subscription. However, we really wanted to allow our users to synchronize their own laptop without giving them full db_owner rights to the database.
Our solution was to enable mixed mode authentication on the subscribers and add a SQL Server user whose sole purpose was to enable our end users to synchronize their laptops. The SQL Server user, 'syncuser', was given the db_owner role on the local subscription database. Then, when we called replmerg.exe from within the program, we specified the following switches:
-SubscriberSecurityMode 0 -SubscriberLogin syncuser -SubscriberPassword 4w3$0m3_P4$$w0Rd
