Root certificate

This section describes how the master Qlik Sense Repository Service (QRS) on the central node in a site handles the root certificate when a Qlik Sense service starts.

The root certificate is located in the following places in the Microsoft Windows certificate store:

Current User>Trusted Root Certification Authorities>Certificates

Local Computer>Trusted Root Certification Authorities>Certificates

When a Qlik Sense service starts, the QRS searches the certificate store to see if there are any Qlik Sense certificates. Depending on the results of the search, the QRS does the following:

• If no root certificate is found, the QRS creates a new certificate.
• If only one root certificate is found, the QRS checks if it is valid. If it is not valid, the QRS logs a fatal error that an invalid root certificate was found, which means that the service is shut down and that the administrator manually has to delete any unwanted certificates. In addition, the QRS logs information on the certificates that are affected by this.
• If more than one root certificate is found, the QRS logs a fatal error that an invalid root certificate was found, which means that the service is shut down and that the administrator manually has to delete any unwanted certificates. In addition, the QRS logs information on the certificates that are affected by this.
