If you already have your SSL Certificate and just need to install it, see
SSL Certificate Installation for Cisco Mobility Server.
For those who may not be familiar with SSL certificate management using an SSL keystore file, Cisco Unified Mobility Servers have a built-in interface to help guide you through your CSR creation process.
During the initial server configuration, you may have created a self-signed certificate. These instructions aim not at creating a self-signed certificate, but a fully functional, CA-signed SSL certificate.
Server Name: Also known as your common name, this is usually the fully qualified domain name through which your server will be accessed externally (e.g., www.yourdomain.com or *.yourdomain.com).
Department Name: The name of your department within your organization. If this is not applicable, go ahead and enter the organization name twice.
Company Name: The full legal name of your organization. For example, if your organization is named Example Company Name, Inc., but goes by Example, enter Example Company Name, Inc.
City: Usually, the main office of your organization. The city does not need to be the city where you or your server is located.
State: Usually the location of your organization's main office. Once again, this does not need to have a bearing on your current location or the location of your server.
Country Code: If this is not familiar to you, you can find your country code here.
Password: You will need your password to modify your keystore later. This password should be a minimum of six characters in length.
Click the button to "Submit".
You will have to select the keystore file that was just created, enter your password, and then click "Submit".
A CSR will usually be saved as a .csr or .txt file.
When asked by DigiCert to select your server type, make sure to select Java.
After you receive your SSL Certificate from DigiCert, you can install it.
