Note that in connections:
n
to an endpoint, the VCS acts as the TLS server
n
to an LDAP server , the VCS is a client
n
between two VCS systems, either VCS may be the client with the other VCS being the TLS server
n
via HTTPS, the web browser is the client and the VCS is the server
TLS can be difficult to configure. For example, when using it with an LDAP server we recommend that you
confirm that your system is working correctly before you attempt to secure the connection with TLS. You are
also recommended to use a third party LDAP browser to verify that your LDAP server is correctly configured
to use TLS.
