Certain Aruba Mobility Controller configurations may require a SSL certificate. If you need to install or update an existing SSL certificate follow these steps.

1. Download the certificate from your provider. Make sure you grab any intermediate and root certificates applicable.
2. Merge the server, intermediate(s), and root certificates into a single .crt file.
3. Convert the .crt certificate to a PKCS#12 (.pfx) file. You'll need the private key password to complete this conversion and don't forget to apply an export password or Aruba ClearPass will refuse the import.
4. Navigate to "Configuration", "Management", "Certificates" and import the certificate.
5. Once uploaded navigate to "Configuration", "Management", "General" and apply the certificate under the WebUI Management Authentication Method via the Server Certificate form.
6. Once complete set a calendar reminder for when the certificate expires.
