Answer:
Active Directory
Explanation:
Active Directory (AD) is a Microsoft product that consists of several services that run on Windows Server to manage permissions and access to networked resources.
Active Directory categorizes objects by name and attributes. For example, the name of a user might include the name string, along with information associated with the user, such as passwords and Secure Shell (SSH) keys.
HTML: Hypertext Markup Language. It's used in conjunction with CSS (Cascading Style Sheets), which implements presentation (adding color, positioning elements, etc.) and JavaScript (you'll often see this referred to as JS), which implements functionality (like clicking on buttons) for webpages.
The PHP code is given below:
<h3>PHP code</h3>
if(isset($_REQUEST['login_btn'])){
$email = filter_var(strtolower($_REQUEST['email']),FILTER_SANITIZE_EMAIL); //strtolower changes email to all lower case
$password = strip_tags($_REQUEST['password']);
The remaining code is in the file attached.
