(Sorry for my terrible English)
I need to do a search with Ldap in AD that finds users who have at least one group, any suggestion?
Thanks a lot
Ended up as simple as it can be.
(&(objectCategory=user)(memberOf=*))
The reason is, memberOf LDAP filter does not count for "primary" group membership, which for AD DS is normally "Domain Users" and all users are normally members of that group. Therefore, if memberOf is populated, then the user is a member of any other group but primary.

I have a security group called SecurityGroupParent and another security group called SecurityGroupChild. I want to add SecurityGroupChild as a member to SecurityGroupParent. But I cannot see the option Group Memberships as explained here although I have the right role.
You'll need the Groups Administrator or User Administrator role to
edit group membership.
Also please check if you have logged into correct tenant or account in
which you have above roles before adding membership.
Also please note that there are some limits while using nesting of groups.
For example: We cannot add group which is synced with on-premises Active Directory.
See Limitations - groups - Azure Active Directory - Microsoft Entra | Microsoft Docs
You can also try to add child security group as a member to the parent security group from members blade:
If the groups are set to role assignable or IsAssignableToRole is
set to $True, then the groups are private and only members can view
the content of the group.
Also check , if HiddenMembership is enabled. reference: visibility
I am querying Active Directory from SQL Server via a Linked Server called LDAP.
The linked server was created thus, authenticating through a specially created service account myDomain\ServiceAccountWithNoPermissions.
exec master.dbo.sp_addlinkedserver #server = N'LDAP', #srvproduct=N'Active Directory Service Interfaces', #provider=N'ADSDSOObject', #datasrc=N'adsdatasource'
exec master.dbo.sp_addlinkedsrvlogin #rmtsrvname=N'LDAP',#useself=N'False',#locallogin=NULL,#rmtuser=N'myDomain\ServiceAccountWithNoPermissions',#rmtpassword='########'
And I'm querying the members of a specific Active Directory Group with the following:
select *
from OpenQuery (LDAP, '
select objectGUID, sAMAccountName
from ''LDAP://myServer.myDomain.com/DC=myDomain,DC=com''
where MemberOf=''CN=Some Group,OU=Folder,DC=myDomain,DC=com''
order by sAMAccountName asc
');
Here's my problem. The above system is working correctly for some Active Directory Groups and not others.
By default I think Authenticated Users is supposed to be able to query any User or Group objects in Active Directory. And as a test I verified that the effective permissions of myDomain\ServiceAccountWithNoPermissions includes "Read all properties" on Groups for which the members are both queryable and non-queryable.
What could be the difference between Groups that are queryable and non-queryable?
You didn't describe what you mean by it working incorrectly, so I can only guess. But the most obvious thing I can see is that you're querying the membership of a group by using memberOf. Depending on how your environment is setup, that may not give you all the results you hope for. I wrote about this, but here's the important part:
Groups only get added to memberOf if they have a Group Scope of:
Universal and are in the same AD forest as the user, or
Global and are on the same domain.
Groups do not get added to memberOf if they have a Group Scope of Global and are on another domain (even if in the same forest).
On top of that, memberOf will only include Domain Local groups from the same domain of the server you are retrieving results from. (if you are working in a multi-domain environment and reading from a Global Catalog, this may not be the same domain the user is from)
It will also not report the user’s primary group (usually Domain Users), if that’s important to you, nor will it include groups on external trusted domains.
The most reliable way to find all the members of a group is to read the member attribute of the group itself. But if the group is used as the primary group for any users, then you would also have to use a different way to find those.
I have a question similar to: On premise Active Directory ObjectId is different than Azure Active Directory ObjectId
We used objectGUID in AD to uniquely identify the users and groups. We also maintain the group memberships using objectGUID. When querying Microsoft tenant using Microsoft Graph, what we see for the id from User or Group objects is different from what we get from the on-prem AD. This makes it difficult to correlate the AAD and AD resources.
I tried to use onPremisesImmutableId using the request below, only to find that this id is my employee id.
/v1.0/me?$select=id,userPrincipalName,onPremisesSecurityIdentifier,displayName,onPremisesImmutableId
Any idea how to retrieve the same objectGUID in the AAD world? I could not find anything close by looking at the User documentation.
Also for Group objects, I could not find the property onPremisesDomainName, similar to that in User objects. Is this by design?
That was the correct answer back when was written but things have changed a bit since then. There is an excellent blog post at Azure AD Connect: objectGUID vs. mS-DS-ConsistencyGuid that discusses this change. Specifically this bit:
Before Azure AD Connect version 1.1.524.0, Azure AD Connect (but also Azure AD Sync and DirSync) defaulted to the objectGUID attribute for objects as the source anchor. Azure AD Connect version 1.1.553.0, and beyond, defaults to the mS-DS-ConsistencyGuid for user objects, but objectGUID for groups and computer objects.
In your case, it sounds like your particular tenant mapping was configured differently (i.e. your employee id).
Given the issues raised in the blog post, I'd recommend against using objectGUID for this purpose altogether. If you're looking for a single property across both User and Group resources, I'd suggest looking at onPremisesSecurityIdentifier instead. This holds the SID from your on-prem AD.
i have a ldap query that only searchs for active users.
The query is the following:
"(&(objectclass=user)(objectcategory=person)(!userAccountControl:1.2.840.113556.1.4.803:=2)(whenchanged>=#LAST_DAYS#))"
I assumed that i only had to remove the "!" to get the inactive users, but i was wrong. Any ideas?
Are you sure that (whenchanged>=#LAST_DAYS#) is correct? If yes, try to query accounts without using userAccountControl and see if it returns more accounts than when you use =2. 2 stands for UF_ACCOUNT_DISABLE and corresponds to "Account is disabled" flag in the Account Properties (user may not login to the domain). You can also go to AD and see if accounts have that flag enabled.
I need a LDAP query for windows server 2012 AD starting from the username of a user and getting all his collegues. In my AD collegues ad identified with the same PRIMARY group.
Is it possibile or should I need a two step query?
Thank you.
Unfortunately, LDAP filtering syntax does not allow for sub-queries within the expression.
You'd have to break this into two parts - first get the user's DirectoryEntry record, then use his PrimaryGroupID in a separate filter, something like :
(&(objectClass=user)(sAMAccountName=JSmith)
Now let's say JSmith is part of the default "Domain Users" group (513) :
(&(objectCategory=person)(objectClass=user)(primaryGroupID=513))
This will return all users that share that same PrimaryGroupID.
