Search for specific entry in Get-Aduser - directreports - powershell

Question

I have a list of user samaccount names that I need query for the manager attribute. Then I need to query the results (DN) of the manger account for the accounts directs reports, there will be multiple on each account. Then I need to search for direct report that contains "(admin)" in it (in the DN). I need that full DN and none that dont match (there should only be one)
My input is currently a get-aduser for testing. Everything works up to the "where"
I think I'm very close I just cant seem to get the last step
Get-Aduser -filter {cn -like "ea8f"} -Properties directreports -server domain.com |
select-Object -ExpandProperty directreports | Where $_.directreports -Contains "(admin)"
Where-Object : Cannot validate argument on parameter 'Property'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

Answer 1

Ok, I have not tested this at the moment, but I think this may work:
# read the users SamAccountNames from the file and loop through
$result = Get-Content -Path 'THE LIST.txt' | ForEach-Object {
# get the Manager attribute
$managerDN = Get-ADUser -Identity $_ -Properties Manager | Select-Object -ExpandProperty Manager
if ($managerDN) {
# if set, use Get-ADUser on the manager DN and try and find the DirectReports that contain the string "(admin)"
Get-ADUser -Identity $managerDN -Properties DirectReports |
Select-Object -ExpandProperty DirectReports |
Where-Object { $_ -match '\(admin\)'} |
ForEach-Object {
# output this DN
$directReports
}
}
}
# output to console
$result

This is what ended up working for me 100%, thanks to everyone who contributed I used something from everyone.
$input = Get-Content -Path $path
$results = #()
#Process each account
ForEach ($user in $input)
{
$current = get-aduser -Filter {samaccountname -like $user} -server $server -Properties Directreports |
Select-Object -ExpandProperty DirectReports |
Where-Object { $_ -match '\(admin\)'}
$dr = New-Object -TypeName PSObject
$dr | Add-Member -MemberType NoteProperty -Name SAM -Value $user
$dr | Add-Member -MemberType NoteProperty -Name Password -Value "z,7'*FBU+"
$dr | Add-Member -MemberType NoteProperty -Name TargetOU -Value $current.Substring($current.IndexOf('OU='))
$dr
$results += $dr
}
$results
