  • 0

I’m trying to list everyone in a security group in an active directory without using CmdLets in PowerShell. The weird thing with my script is that it works if I list the entire directory but if I try and specify with an ldap query what I want to be listed it does not work. I know my ldap query is correct because I have used it in another similar vbs and it works. The commented lines are where i have tried to put in the query.

$strFilter = "(&(objectCategory=person)(objectClass=user))"
#$strFilter = "(&(objectCategory=person)(objectClass=user)(memberOf=CN=Common Name,OU=User Groups,...,DC=ad,DC=domain,DC=com))" #... is just left out part of query

#$objDomain = New-Object System.DirectoryServices.DirectoryEntry
$objDomain = New-Object System.DirectoryServices.DirectoryEntry("LDAP://CN=Common Name,OU=User Groups,...,DC=ad,DC=domain,DC=com") #... is just left out part of query

$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.PageSize = 1000
$objSearcher.Filter = $strFilter
$objSearcher.SearchScope = "Subtree"

$colProplist = "name"
foreach ($i in $colPropList){$objSearcher.PropertiesToLoad.Add($i)}

$colResults = $objSearcher.FindAll()

foreach ($objResult in $colResults)
    {$objItem = $objResult.Properties; $objItem.name}

    Here is something working in an Active-Directory 2003 SP2 and 2008 R2. I use ADSI and Microsoft LDAP_MATCHING_RULE_IN_CHAIN. It Search recursively (but in one query) all the users from a group (be careful it return users from security and distributions group)

    Clear-Host
$dn = New-Object System.DirectoryServices.DirectoryEntry ("LDAP://WM2008R2ENT:389/dc=dom,dc=fr","jpb@dom.fr","PWD")

# To find all the users member of groups "MonGrpPlusSec"  : 
# Set the base to the groups container DN; for example root DN (dc=societe,dc=fr)  
# Set the scope to subtree 
# Use the following filter : 
# (member:1.2.840.113556.1.4.1941:=CN=MonGrpPlusSec,OU=ForUser1,DC=dom,DC=fr) 

$dsLookFor = new-object System.DirectoryServices.DirectorySearcher($dn)
$dsLookFor.Filter = "(&(memberof:1.2.840.113556.1.4.1941:=CN=MonGrpPlusSec,OU=ForUser1,DC=dom,DC=fr)(objectCategory=user))"; 
$dsLookFor.SearchScope = "subtree"; 
$n = $dsLookFor.PropertiesToLoad.Add("cn"); 
$n = $dsLookFor.PropertiesToLoad.Add("distinguishedName");
$n = $dsLookFor.PropertiesToLoad.Add("sAMAccountName");

$lstUsr = $dsLookFor.findall()
foreach ($usrTmp in $lstUsr) 
{
  Write-Host $usrTmp.Properties["samaccountname"]
}
