I'm trying to know if a specific user is member of a specific OU.
Use the -SearchBase parameter with the Get-ADUser cmdlet from the ActiveDirectory RSAT module to narrow your query to a specific subtree:
$ADUser = Get-ADUser -Filter "SamAccountName -eq 'lmontoya'" -SearchBase "OU=TargetOU,DC=domain,DC=tld"
Beware that it will default to a recursive subtree search by default, so if you need to test whether the user is present directly under that OU (as opposed to just somewhere under the OU), you need to specify a -SearchScope as well:
$ADUser = Get-ADUser -Filter "SamAccountName -eq 'lmontoya'" -SearchBase "OU=TargetOU,DC=domain,DC=tld" -SearchScope OneLevel
If the user isn't found with the specified criteria, $ADUser will be empty
The SearchBase/SearchScope parameters work with all the query cmdlets in the module, so you can use the same approach for computers or OUs or whatever else you need to find in a specific container:
# Query all the computer account objects residing at "OU=TargetOU,DC=domain,DC=tld"
Get-ADComputer -Filter * -SearchBase "OU=TargetOU,DC=domain,DC=tld" -SearchScope OneLevel

I receive task on studies to create command that will find a specific users in specific OU in Active Directory.
More precise, find all persons that name is A* and are located in OU *es.
After hours of researching I created such commands:
For finding all A* users:
Get-ADUser -filter {name -like "A*"}
For finding all *es OU
Get-ADObject -filter {OU -like "*es"}
And I don't have idea how to connect those outputs.
I was thinking about such resolutions, but they don't work for me.
$var = Get-ADObject -filter {OU -like "*es"} | Select DistinguishedName
Get-ADUser -filter {name -like "A*"} -SearchBase $var
Or
Get-ADUser -filter {name -like "A*" -and OU -like "*es"}
I'm lost, please advice.
You could first use the server filter to get all A*users and then filter the OU on the client using the Where-Object cmdlet:
Get-ADUser -filter {Name -like 'A*'} | Where-Object DistinguishedName -like '*OU=*es*'
If you know all your OU you want to filter, consider using the -SearchBase Parameter. More information here.
I am testing powershell with active directory,
have created list of OU in particular domain, but unable to remove all the OU from AD, Want to remove all OU except built in from AD
below is the script i am using, but it is giving access denied-
using administrator id
Get-ADOrganizationalUnit -Filter {Name -notlike "Domain Controllers"} -SearchBase (Get-ADDomain).Distinguishedname -SearchScope OneLevel | Remove-ADOrganizationalUnit -Recursive -Confirm:$false
OU's are protected by default, you have to remove that flag before deleting:
Set-ADObject -ProtectedFromAccidentalDeletion $false
I'm trying to remove all the principal group memberships starting with the name of all computer accounts in one specific ou.
I've tried browsing to the OU with the AD provider, typing gci and getting a list of all the computers in the ou to find their ADPrincipalGroupMembership which works. Also, using get-adcomputer -searchbase <ou> -filter * works too. But I can't then remove every group that each machine is a member of.
When I then try to expand on that with remove-ADPrincipalGroupMembership, my input for the groups to remove are system.string and remove-ADPrincipalGroupMembership won't accept that. I have something like this so far/
Get-ADComputer -SearchBase 'OU=blahblah' -Filter * |
Remove-ADPrincipalGroupMembership -MemberOf (Get-ADGroup -Filter 'name -like "17"')
I've read help and examples but I can't find how to do this. I don't want to give up and just use the gui :)
thank you
You can try this...I am not able to test it to confirm it works, but I think it should.
$Comps = Get-ADComputer -SearchBase 'OU=blahblah' -Filter * -Prop MemberOf
Foreach ($Comp in $Comps)
{
$Groups = $Comp.MemberOf | ? {$_ -like "CN=17*"}
if ($Groups)
{
Remove-ADPrincipalGroupMembership -Identity $Comp -MemberOf $Groups -Whatif #-Confirm $False
}
}
Assuming it works with the -whatif statement, by default I believe that command will prompt you if you're sure about each removal which could be a pain so you could uncomment -confirm $false to try and avoid that.
Also it is assuming the distinguished name of each group is going to be something along the lines of
CN=17groupA,OU=Computer Groups,OU=Computer,DC=TEST,DC=NET
So I have a script with the purpose of scanning devices that start with a certain name, then return results of computers missing a group. My problem is, the device I need it to run from turns out not to be in the same tree. I have seen some commands, but I wanted to be sure I had the syntax right. I will include part of the script for context:
Import-Module ActiveDirectory
$Group = "A-Certain-Group"
$Groupname = (Get-ADGroup $Group).distinguishedName
$Computers = Get-ADComputer -filter "name -like 'Big*'" -Prop MemberOf | Where{$_.MemberOf -notcontains $Groupname}
So let's say I am running it from "company.net", and it needs to perform the above script on "companynet.net" instead. What is the proper method?
The AD cmdlets all have a -server parameter which lets you specify other domains. Just use it to specify the other domain assuming there is a trust.
$Groupname = (Get-ADGroup $Group -Server companynet.net).distinguishedName
$Computers = Get-ADComputer -Server companynet.net -filter "name -like 'Big*'" -Prop MemberOf | Where{$_.MemberOf -notcontains $Groupname}
Note that if you don't have permission to perform actions in the domain you will also need to use the -credential parameter.
How do you search multiple OU's in Active Directory. Say if there are 4 OU's for different users, and need to search only 3 of the 4.
Currently I am using the below to search one path, how would I expand that to search multiple OU's.
$OU='AD Path'
Get-ADUser -SearchBase $OU -Properties Lastlogondate -filter {lastlogondate -lt $DisableDays}
It looks like -searchbase takes <string>, so you would need to loop through OUs.
The following query would get users in each OU:
$OU=#('cn=users,dc=xyz,dc=com','ou=companyusers,dc=xyz,dc=com')
$ou | foreach { get-aduser -searchbase $_ ...}
