Going through the documentation it states that Kiwi Syslog Server does not check client certificate and accepts TLS connection from any client. Why? Is there a plan to check the client certificate in the future?
Certificates:
TLS relies on certificate-based authentication. A proper certificate has to be selected from certificate store before any client will be able to successfully connect to Kiwi Syslog Server using TLS secured TCP channel. "Select Certificate" button allows the user to browse local certificate stores and pickup a suitable certificate. The selected certificate is used to prove identity of Kiwi Syslog Server to the client. The server itself does not check client certificate and accepts TLS connection from any client.
