If a server certificate is signed by a CA that is not trusted by iPads and iPhones that run Horizon Client for iOS, you can configure the device to trust the root and intermediate certificates. You must distribute the root certificate and all intermediate certificates in the trust chain to the devices.


  1. Send the root certificate and intermediate certificates as email attachments to the iPad.
  2. Open the email attachment for the root certificate and select Install.
    The certificate displays the following message:
    Unverifiable Profile. The authenticity of Certificate name cannot be verified. Installing this profile will change settings on your iPad.
    Root Certificate. Installing the certificate Certificate name will add it to the list of trusted certificates on your iPad.
  3. Select Install again.
  4. Repeat steps 2 and 3 for all intermediate certificates in the trust chain.
