01. How to Generate Customized Certificate?

Several tools are available to create self-signed certificates. In this tutorial, we will use OpenSSL to create a self-signed certificate for secure LDAP.

To get started:

1. Generate the certificate:

   • Download FreeRADIUS code from https://github.com/FreeRADIUS/freeradius-server/tree/master/raddb/certs.

   • Navigate to the directory: cd raddb/cert/

   • Adjust the customized information in the .cnf file (e.g., domain name, expiration duration, location, etc.).

   • Run the bootstrap script: ./bootstrap

   • Zip the certificate files: zip cert.zip server.pem dh ca.pem

2. Click Import and Zip File Upload to upload cert.zip to EnGenius Cloud.

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

Note:

Some browsers might complain about the self-signed certificate and display a "Not Trusted" warning message. If so, the user needs to search for an official Certificate Authority (CA) to apply for a formal CA certificate to avoid the warning message.
