Hello,

I execute the following and get the error that follows.  The $IDs vaiable is a PSCustomObject object, but Get-Aduser wants a type of ADUser object.  So how can a pass a CSV file of PSCustomObjects to a Get-ADuser cmdlet?

$IDs = import-csv testids.csv
foreach ($Account in $IDs) {
$IDAttrs = get-aduser $Account -properties *
The CSV file has SamAccount Names as follows:
ID
__
AU
DU
Joe

Get-ADUser : Cannot bind parameter 'Identity'. Cannot convert the "@{ID=AU}" value of type "System.Management.Automation.PSCustomObject" to type "Microso
ft.ActiveDirectory.Management.ADUser".		

Try like this way :

IDs = import-csv testids.csv
foreach ($Account in $IDs) {
$IDAttrs = get-aduser $Account.ID -properties * 
}

Thanks Tarique....that works, but why?

The $Account.ID is a System.String object type, but the Get-Aduser wants a ADUser object type?  Im confused.

becouse in your csv   you have  ID header   and you are passing the value from CSV .

see help on Get-aduser :

PS C:\Temp> Get-Help Get-ADUser -Parameter identity
