You can set up TLS between the JFrog Platform and external services by trusting external service certificates. JFrog services will not allow a SSL/TLS connection with an external service without a validation of the trusted CA certificate.
For example, you may want to connect to remote repositories, your LDAPS, internal proxy, OAuth server, or other external services over HTTPS. To that end, you may need to trust a certificate (for example, a self signed certificate) that was not signed by a trusted Certificate Authority (CA) and is used by the external service.
