When accessing EPM Workspace servers running on HTTPS protocols, the server's security certificate must be issued by a trusted company. To avoid unnecessary prompts when importing documents, you must add the security certificate into the Internet Explorer certificate path on the Smart View client's machine.
To add security certificates:
In Internet Explorer, connect to EPM Workspace; for example:
https://<workspace_webserver>:<port>/workspace/index.jsp.
If prompted with the warning message, “The security certificate was issued by a company you have not chosen to trust,” select View Certificate.
Ensure that all certificates in the certification path have been trusted.
