SSL authentication (apache) similar to ssh (authorized_keys)?

Question

Apache HTTP Server

Hello.
I am tormented by the question, is it possible to implement user authentication on a web server using certificates, but without organizing a CA? Those. as in the case of ~.ssh/authorized_keys2, we add the user's certificate to some analogue on Apache and authenticate it, i.e. some local database of "trusted certificates"?
I know it's conceptually wrong and breaks the coherent PKI architecture, don't ask me why I need it. We need an analogue of authorized_keys, but for apache. Is there one, friends?
