Trust GlobalSign-validated Signatures in Kofax PowerPDF

Issue

When signing a document with the help of Kofax SignDoc Cloud, the signature might be shown as problematic when viewing the document with Kofax PowerPDF.

The message that is shown states "This document is signed. At least one signature has problems."

Cause

The GlobalSign Root Certificate is not installed and trusted by default.
