Powershell DirectorySearcher Null Output - powershell

Question

I'm writing a powershell script that searches for users inside an Active Directory OU and allows me to reset passwords by choosing matches from a list. I found a Tutorial that uses the System.DirectoryServices.DirectoryEntry and System.DirectoryServices.DirectorySearcher, and modified it like so:
$objDomain = New-Object System.DirectoryServices.DirectoryEntry("LDAP:\\[REDACTED]")
##ReadSTDIN
$strSearch = Read-Host -Prompt "Search"
$strCat = "(&(objectCategory=User)(Name=*" + $strSearch + "*))"
## Search Object
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.PageSize = 1000
$objSearcher.Filter = $strCat
$objSearcher.SearchScope = "Subtree"
#Load Required Properties into the dynObjLink
$objSearcher.PropertiesToLoad.Add("name")
$objSearcher.PropertiesToLoad.Add("userPrincipalName")
$objSearcher.PropertiesToLoad.Add("SamAccountName")
##Magical Search Function
$colResults = $objSearcher.FindAll()
$colResults.PropertiesLoaded
#for every returned userID add them to a table
ForEach ($objResult in $colResults)
{$a++
$objResult.count
$objItem = $objResult.Properties
$objItem.name
$objItem.userPrincipalName
$results.Add($a, $objItem.name + $objItem.userPrincipalName + $objItem.SamAccountName)
}
#Print Table
$results | Format-Table -AutoSize
This works well enough, but when it prints data I can only get the "first name" value of anything that comes back. Everything else becomes NULL and I can't figure out why.
Name Value
---- -----
3 {James3 [REDACTED], $null, $null}
2 {James2 [REDACTED], $null, $null}
1 {James1 [REDACTED], $null, $null}
I've tried different kinds of authentication and manipulating values, but the DirectorySearcher object only seems to collect the "name" value of any record it returns, no matter what I load into it. Help?

Answer 1

Here's a bit shorter (and PowerShell v2-compatible) way of doing this:
#requires -version 2
param(
[Parameter(Mandatory=$true)]
[String] $SearchPattern
)
$searcher = [ADSISearcher] "(&(objectClass=user)(name=$SearchPattern))"
$searcher.PageSize = 1000
$searcher.PropertiesToLoad.AddRange(#("name","samAccountName","userPrincipalName"))
$searchResults = $searcher.FindAll()
if ( $searchResults.Count -gt 0 ) {
foreach ( $searchResult in $searchResults ) {
$properties = $searchResult.Properties
$searchResult | Select-Object `
#{Name = "name"; Expression = {$properties["name"][0]}},
#{Name = "sAMAccountName"; Expression = {$properties["samaccountname"][0]}},
#{Name = "userPrincipalName"; Expression = {$properties["userprincipalname"][0]}}
}
}
$searchResults.Dispose()
Note that there's no need to build a list and output afterwards. Just output each search result. Put this code in a script file and call it:
PS C:\Scripts> .\Searcher.ps1 "*dyer*"
If you omit the parameter, PowerShell will prompt you for it (because the parameter is marked as mandatory).

Answer 2

try using Properties matching to the PropertiesToLoad
$entry = new-object -typename system.directoryservices.directoryentry -ArgumentList $LDAPServer, "ldap", "esildap"
$entry.Path="LDAP://OU=childOU,OU=parentOU,DC=dc1,DC=dc2"
$searcher = new-object -typename system.directoryservices.directorysearcher -ArgumentList $entry
$searcher.PropertiesToLoad.Add('samaccountname')
$searcher.PropertiesToLoad.Add('mail')
$searcher.PropertiesToLoad.Add('displayname')
$objs = $searcher.findall()
foreach($data in $objs)
{
$samaccountname = $data.properties['samaccountname'][0] + ''
$mail = $data.properties['mail'][0] + ''
$displayname = $data.properties['displayname'][0] + ''
}
when accessing the properties of the resultset you get a System.DirectoryServices.ResultPropertyValueCollection type for each property
to get a string value for passing to a database the property value access the zero index of the object
