## How to Generate Customized Certificate? 

There are several tools available to create self-signed certificates. This tutorial lets you create a self-signed certificate for Active Directory by using OpenSSL.

* Get started to generate a certification file

  * Download Freeradius code from the link below: <https://github.com/FreeRADIUS/freeradius-server/tree/master/raddb/cert>
  * cd to **raddb/cert/**&#x20;
  * Adjust customized information in the .cnf file, e.g., domain name, expiration duration, location, etc.
  * **./bootstrap**
  * zip cert.zip **server.pem dh ca.pem**

* Click Import and upload cert.zip to the EnGenius Cloud

* Export ca.pem and install it on the client device if requested.

Note: Some browsers might pop up a Not-Trusted warning message for self-signed certificates. If this is the case, the user must search for an official Certificate Authority (CA) to apply for a (CA) certificate to avoid the warning message.

## Supported Operating Systems and Models

EAP-PEAP/MSCHAPV2 and TLS 1.2+ are essential on client devices for Active Directory authentication. The following operating systems have native support and get verified working with EnGenius Cloud AP: (updated on 4/20/2022)&#x20;

* iOS version 13 and higher.&#x20;
* Google Chrome OS&#x20;
* Android version 6 and higher
* Microsoft Windows 8 and higher&#x20;
* macOS 11 and higher&#x20;
