The cacert.pem file

This file is used to validate the Verify server certificate when secure TLS connections are made from IcbLdapSync.exe to Verify.

A sample certificate authority file is provided, cacert.pem.samplethat is copied to cacert.pem during the installation process. This file contains a list of all major certificate authority certificates.
To increase security, remove all certificate authority entries from cacert.pem that are not involved with the signing of your Verify server certificate.
