AdHelper.ps1

function Get-ADObject($adspath){
    $obj = new-object System.DirectoryServices.DirectoryEntry "LDAP://$adspath";
    new-object PSObject -Property:$obj.Properties;
}

function Find-ADUserByLogin($login){
    $ds = new-object System.DirectoryServices.DirectorySearcher
    $ds.Filter = "(samAccountName=$login)";
    $result = $ds.FindOne();
    if($result){
        $memberof = $results.Properties.memberof;
        $obj = new-object psobject -Property $result.Properties
        Add-Member -InputObject:$obj -MemberType:ScriptMethod -Name:GetGroups -Force:$true -Value:{
            $memberof | % { Get-ADObject $_ };
        }.GetNewClosure();
        
        $obj;
    }
}

function Find-ADUserByName($firstName, $lastName){
    $ds = new-object System.DirectoryServices.DirectorySearcher
    $ds.Filter = "(&(objectCategory=user)(givenName=$firstName)(sn=$lastName))";
    $result = $ds.FindOne();
