I was just going through the various permissions in the security tab of a user in active directory. I came across the permission "Create all child objects." I thought Users cannot have other objects within them as they are not a container. Then
what does this permission mean?

'Create all child objects' in the security tab of a user? Users have child objects?

Purpose of Distribution groups in Active Dirctory.
When mails could be distributed even using security groups, why do w need distribution groups in active directory? Every post I see only lists the differences between Security and Distribution groups, but why distribution groups are needed in the first
place when the same function can be achieved through security groups

Difference between 'Never expire' and 'Not Defined' with regard to the Maximum password age field.
So I read that the value 0 in the Maximum password age field refers to the option of never expire, while a value of negative 1 refers to the option of not defined. What is the difference between the two? What happens when a value is not defined?

Extending Active Directory into China (Data privacy and regulatory concerns)
We are a North American company with head office in China (China office already a different forest and domain). However, we want to extend the North American domain and Active Directory into China. The employees of China office will be using ~80% of the services
currently utilized globally. This includes all the SSO, Exchange, same O365 Tenant, etc.
There have been some concerns raised about replicating non-Chinese employee's AD data (and other regulatory considerations like GDPR) through the Great Firewall of China. The new cybersecurity laws in China allow PKI and AD traffic encryption but not without the ability for the government to have access to this information.
I am wondering what have other companies in North America and Europe done to overcome this challenge?
We chatted shortly about a stand alone forest with a trust but this may or may not be the best solution.

Active Directory 2019 - did something change with how member, memberOf, and whenChanged operate?
I have the following scenario.
I recently installed a fresh Windows Server 2019 with Active Directory Domain Services enabled. So far so good.
I have user accounts in my active directory.
I have groups in my active directory.
I then use an LDAP Python library ldap3 to add a user to a group:
def add_group_members(ldap_host, ldap_domain, ldap_user, ldap_password, group_dn, members):
tls_configuration = Tls(validate=ssl.CERT_NONE, version=ssl.PROTOCOL_TLSv1)
server = Server(ldap_host, use_ssl=True, get_info=ALL, tls=tls_configuration)
conn = Connection(server, user="{}\\{}".format(ldap_domain, ldap_user), password=ldap_password, authentication=NTLM)
conn.bind()
conn.modify(group_dn, {'member': [(MODIFY_ADD, members)]})My user now has a memberOf attribute with the DN of the group.
And my group has a member attribute with the DN of the user. Great.
Now I remove the user from the group:
def remove_group_members(ldap_host, ldap_domain, ldap_user, ldap_password, group_dn, members):
tls_configuration = Tls(validate=ssl.CERT_NONE, version=ssl.PROTOCOL_TLSv1)
server = Server(ldap_host, use_ssl=True, get_info=ALL, tls=tls_configuration)
conn = Connection(server, user="{}\\{}".format(ldap_domain, ldap_user), password=ldap_password,
authentication=NTLM)
conn.bind()
conn.modify(group_dn, {'member': [(MODIFY_DELETE, members)]})The group and user object no longer have memberOf or member attributes as expected.
The group object's whenChanged is modified with the timestamp of when the group membership of the user changed.
But the user's whenChanged attribute is *not* modified.
This did not seem to be how Active Directory worked on my previous Windows Server 2016 setup.
The user object did change. The memberOf was removed. I expect the whenChanged to be updated to respect that.
Why am I seeing this behavior?

PowerShell script for Event ID LDAP
Hi all,
according to the upcoming changes by LDAP we have to perform some audit of the logs and find the connections and accounts.
From what I've see there will be Event ID 3040 and 3041 which will collect the information every 24 hours. I've tried to test so far with the current Event IDs but with Directory Service logs and then export to cvs didn't worked very well.
Did someone already to create a powershell script to export the information from the events and save them readable in scv?

Windows 2016 BPA error - Cannot find directory server with identity: 'UServer$'
Hi Support,
When run the BPA in the Windows 2016 DC, we found one of the DC have many error as below:
Issue:
The Active Directory Domain Services Best Practices Analyzer (AD DS BPA) is not able to collect data about the hostname DNS A/AAAA records from the DNS servers.
Impact:
The AD DS BPA will not be able to validate configuration data about the hostname DNS A/AAAA records.
Resolution:
Troubleshoot the DNS servers to determine the root cause of the problem.
When check the DirectoryServices_EngineRe

I checked DNS have the server record. Try to use ntdsutil and the server can be found. The replication on all DC is healthly.
Any idea?

Authentication failure - Bad password
I have a lot of the following event for multiple user
--------------------------------------------------
Kerberos pre-authentication failed.Account Information:
Security ID: Domain\xxxx
Account Name: xxxx
Service Information:
Service Name: krbtgt/Domain
Network Information:
Client Address:::ffff:X.X.X.X
Client Port: 37430
Additional Information:
Ticket Options:0x40810010
Failure Code: 0x18
Pre-Authentication Type:2
Certificate Information:
Certificate Issuer Name:
Certificate Serial Number:
Certificate Thumbprint:
Certificate information is only provided if a certificate was used for pre-authentication.
Pre-authentication types, ticket options and failure codes are defined in RFC 4120.
If the ticket was malformed or damaged during transit and could not be decrypted, then many fields in this event might not be present.
-------------------------------
The problem with this is that the account lockout policy cannot be applied because user accounts that display this behavior are immediately locked out.
Will you have some reference in this regard?

Microsoft Active Directory paged result is returning less number of records than page size even though the server has more records
We have Microsoft Active Directory which has 1 million entries. We are using ldapjs node module paging search to retrieve entries from the Active Directory. As per our observation in some retrieve calls the results size returned is less than page size. For example if my page size is 100 and expecting to retrieve 100 results but it is not returning 100 results instead it is returning less number of records even though my active directory server has more than page size records available.
This behavior is intermittent and not fixed. Please suggest if anyone facing same behavior while retrieving data from Active Directory.
Thanks in advance.

AD connect + Exchange migration
We have an on prem AD environment. We installed the AD Connect sync software on an on prem domain member server and established a successful sync with an Azure Tenant.
We did this so that we can start offering Sharepoint services to our users.
We also have a hosted Exchange 2013 environment which we would now like to sync into our AD tenant to take advantage of O365 Exchange.
Is there a preferred method to do this Exchange to Tenant migration. We were suggested by our migration partner to stop the AD sync first, do the Exchange 2013 migration to the tenant and start the sync again
We are concerned this may lead to errors/duplication of UPNs etc.? Does anyone know if there is a documented approach on this? Do we need a CLEAN AD tenant before starting Exchange migration ?

User's memberOf attribute versus Group's member attribute - can these get out of sync?
There are 3 possibilities of how AD behaves:
1) the user has a memberOf pointing to a group, but the group does not have a member attribute pointing back to the user.
2) the group has a member attribute pointing to a user, but the user does not have a memberOf attribute pointing back to the group.
3) the group has a member attribute pointing to a user, and the user has a memberOf pointing to a group
If I am seeing scenario #1 and scenario #2 happen on my enterprise system, is this indicative of a problem?
Because this conversation here:
Active Directory 2019 - did something change with how member, memberOf, and whenChanged operate?
says that the User's memberOf record is not even stored. So how would these ever be out of sync?

Server 2019 Domain Controller Does Not Create IPv6 PTR Record
I have a new Server 2019 domain controller running and my network has IPv4 and IPv6 functionality and a static IP address for both protocols has been configured, in DNS I can see the A and AAAA records created for the domain controller and in the reverse lookup zone for IPv4, I can see the PTR record for the IPv4 address created along with a time stamp added on to it matching today's date and the time of it's registration.
But in the reverse lookup zone for IPv6, no PTR record is created, as a result, if I do nslookup domain.contoso.com the Server shows up as UnKnown because it's preferring IPv6 and no PTR record for the IPv6 address exists. I've tried configuring the DNS Client group policies that specify it should register the PTR record regardless, register it if the A record succeeds, including setting the Refresh Interval policy to 6 hours so that it matches the Refresh Interval for DNS scavenging and fiddling with settings in the Network Adapter such as Use This Connection's DNS Suffix in DNS Registration and Register This Connections Addresses in DNS and nothing changes.
Does anyone have any ideas?
