How to create AD Object "RID Set" in PowerShell? - powershell

I have a question. In AD structure I find AD object RID Set which placed as child of ADComputer object.
If I create new ADComputer object, how can I create RID set object in Powershell? Is it possible?

Is it possible?
No
The RID-Set class is marked System-Only, meaning that only a DSA (iow. the DC itself) can create such an object.
You can verify this by looking at the schema with Get-ADObject:
Get-ADObject "CN=RID-Set,$((Get-ADRootDSE).schemaNamingContext)" -Properties systemOnly
You'll find that the systemOnly attribute is set to $true

How can I set the owner attribute (not managed by) from an AD group by Powershell?

I'm looking for some help on how to get and set the owner attribute (not managed by) on an AD group by Powershell.
After seeing a lot of documentation on Google and other websites, I only find some solutions for the Managed By property...
Do you have some information to help me on my path to the solution?
Thank you in advance for any help.
The Set-ADGroup cmdlet doesn't have an Owner parameter, so it's a little more tricky. But as is the case with all the AD cmdlets, you can use the -Clear and -Replace parameters to work with any attributes that aren't exposed as parameters, and -Add and -Remove for multi-value attributes.
The owner attribute must be set to the distinguished name of the owner account. So you can use Get-ADUser to find the user and use the DistinguishedName property from it.
For example, setting MyUser as the owner of MyGroup would look like this:
Set-ADGroup MyGroup -Replace #{owner = (Get-ADUser MyUser).DistinguishedName}

ADSI Search for DistinguishedName of the primary group based on primarygroupid

Because we don't have the active directory module available on all our systems we're using ADSI instead. The following code retrieves a user object from AD by using the AdsiSearcher:
$ADUser = ([AdsiSearcher]"(samaccountname=$SamAccountName)").FindOne()
This results in finding the property primarygroupid which represents the domain primary group for user, usually number 513. When we have this number we would like to find the distinguishedName of the group. However, the code below does that just fine I was wondering if there is a better filter that can be used instead of filtering after the FindAll() method?
$searcher = [adsisearcher]'objectclass=group'
$searcher.PropertiesToLoad.Add('primarygrouptoken')
$searcher.PropertiesToLoad.Add('distinguishedName')
$searcher.FindAll() |
Where-Object { $_.Properties.primarygrouptoken -eq 513}
Something like this would be great but it's not possible:
([adsisearcher]”(&(objectCategory=group)(primaryGroupid=513))”).FindOne()
The primaryGroupToken is a constructed attribute, meaning that it's not actually materialized in the database, and can't be filtered using LDAP.
In order to build an equivalent filter we'll need to look at how it is constructed - and the primary group token in Active Directory is always the same as the group's RID part (the relative identifier) of the objectSid attribute.
So, if we want to search by it, we can simply filter by objectSid instead:
# Obtain domain SID
$dncDN = ([adsi]"LDAP://RootDSE").defaultNamingContext
$dnc = [adsi]"LDAP://$dncDN"
$domainSID = [System.Security.Principal.SecurityIdentifier]::new($dnc.objectSid.Value, 0)
# Set the group ID we're looking for
$RID = 513
# Search for group by objectSid value:
([adsisearcher]"(&(objectCategory=group)(objectSid=${domainSID}-${RID}))").FindOne()

Adding Active Directory resource groups to a checkedlistbox in Powershell Studio

Right now I have successfully queried active directory to get a list of all of the resource groups avaiable as such:
$AD_ResourceGroups = Get-ADGroup -filter * -SearchBase "OU=Resource Groups,OU=Groups,OU=Paper Transport,DC=papertransport,DC=com"
This is stored in the $AD_ResourceGroups variable. I am then attempting to add that list of the resource groups into the checklist itself like such:
$chklistGroups.Items.Add($AD_ResourceGroups,'Unchecked')
When I launch the GUI, the only thing that shows up in the checkedlistbox is one single entry: Object[]Array
What am I doing wrong here?
Add is used to add a single item. If you're using an array you need to use AddRange which will add the array as single items to your checklistbox.
The issue is that you are adding 1 thing to the list, an array. What you want to do is iterate through the array, and add each item to the list.
$AD_ResourceGroups | ForEach-Object { $chklistGroups.Items.Add($_,'Unchecked') }
Edit: Use Jason Snell's answer, it's better. I forgot about the AddRange method.

Find and replace custom attribute values in AD using Powershell

So I have an interesting script I am trying to figure out, basically I need to change a custom attribute value to a new one. The problem is its for both users and computers and not specific to the groups. So for instance the value might be Billing1 for several users in an OU and this need to be Billing2. So I need to find any instance of the Value of Billing1 and change it to Billing2 not knowing the user or computer object. I can successfully change one at a time if I know who the user is by using Set-ADUser, Set-ADComputer and even with Set-AdObject but I need to figure out a Find and replace function.
I have searched for this and I have found examples of where I can use CSV for users and computers but again I don't know who has what since the value in the attribute can vary and also changes if a reorg happens.
got the correct script...
Get-ADComputer -Properties enterattributename -Filter {enterattributename -like "value to search" } |Set-ADComputer –replace #{ enterattributename =”value to change”}
this also can be applied to Get-ADUser and Get-ADObject

Retrieving an RDN from an Active Directory User Object

Is it possible to retrieve the RDN of a user object in Active Directory with the attribute intact.
I've done a lot of reading on this and found that an AD user object stores the RDN in an property called "name". Supposedly the value of the name (rdn) property should be something like name = "cn=Smith, Joe". The cn attribute is part of what should be returned. However whenever I retrieve the name property of an object the "cn=" always seems to be missing. For instance
$foo = get-aduser -filter 'Name -like "Smith, Joe"'
$foo.name
will return "Smith, Joe" not "cn=Smith, Joe". Is there someway to query and get the full RDN to return?
An alternative, is to grab the full DN of the object, split the DN, and display the first element in the resulting array, which will be the RDN, either CN= or otherwise, object dependent
$((foo.distinguishedname).split(","))[0]
Not really an answer but informations :
First the attributeId of the RDN attribute is fixed by the schema :
On the RDN point of view Active-Directory inherit from X500 standard. That is to say that you don't choose the attribute you want to create the RDN (in other LDAP directories you can). In Active-Directory the RDN attribute is given in the class schema by rDNAttID, it specifies the attributeId of the RDN attribute. If you look the schema for the class user it's CN.
So you can use :
"CN=$((get-aduser 'Smith, Joe').Name)"
Second do the following experiment :
In an OU create a user called 'Mananegement' you have the following DN CN=MAnagement,OU=MyOU,... now try to create, in the same OU, an OU named 'Mananegement' it should create an object with the following DN OU=MAnagement,OU=MyOU,..., but you receive an error. This error makes me beleive that somehow Active-Directory consider 'Mananegement' as the RDN and not 'CN=Mananegement' like others directories.
$current.Substring($current.IndexOf('OU='))
