Script not working to query a certain query

I am trying to query users in AD and only receive output that have a certain group that start with 'IT-'

I am not getting anything in the output, any reasons why?

Const ADS_SCOPE_SUBTREE = 2

Set objFSO = CreateObject("Scripting.FileSystemObject")
strDomain = "dc=domain,dc=com"
strUsers = "c:\Users.txt"

Set objOutput = objFSO.CreateTextFile("c:\output.txt")

aryUsers = Split(objFSO.OpenTextFile(strUsers).ReadAll, vbNewLine)
For Each strUser In aryUsers
  Set objConnection = CreateObject("ADODB.Connection")
  Set objCommand = CreateObject("ADODB.Command")
  objConnection.Provider = "ADsDSOObject"
  objConnection.Open "Active Directory Provider"
  Set objCommand.ActiveConnection = objConnection
  objCommand.Properties("Page Size") = 1000
  objCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE
  objCommand.CommandText = _
    "SELECT ADsPath FROM 'LDAP://" & strDomain & "' WHERE objectCategory='user' " & _
        "AND samAccountName = '" & strUser & "'"
  
  Set objRecordSet = objCommand.Execute
  objRecordSet.MoveFirst
  If Not objRecordSet.EOF Then 
    Do Until objRecordSet.EOF
      strADsPath = objRecordSet.Fields("ADsPath").Value
      Set objUser = GetObject(strADsPath)
      objOutput.WriteLine objUser.Name & " is a member of the following groups:"
     For Each strGroup In objUser.memberOf
     If mid(strGroup,4,4)="IT-" Then  
      Set objGroup = GetObject("LDAP://" & strGroup)
      objOutput.WriteLine objGroup.CN
    End If
 Next
      objOutput.WriteLine
      objRecordSet.MoveNext
    Loop
  Else 
     objOutput.WriteLine strUser & " does not have an AD account!"
  End If

Next

objOutput.Close
Set objOutput = Nothing
Set objGroup = Nothing
Set objUser = Nothing
Set objFSO = Nothing
