When configuring a Certificate Security Provider in a published app environment (Citrix, RemoteApp, XenApp) as a Security Provider, the user who will run Remote Desktop Manager in the RemoteApp environment (Citrix) will require a Read permission on the certificate. If the Read permission is not correctly set, Remote Desktop Manager will generate the CryptographicException - Keyset does not exist error dialog.
Step-by-step guide
These steps require that the certificate has been successfully installed on the machine on which Remote Desktop Manager will run.
- Open Local Machine Certificate Manager on the machine (certlm.msc).
- Locate the Certificates.
- Right click on Certificates - All Tasks - Manage Private Keys.
- Grant the Read permission over the certificate file to the proper group(s) or user(s).
