Yes I have that as well
SSLVerifyClient require
SSLVerifyDepth 10
I also have FIPS enabled (not sure if that matters).
Well, it should be working if everything is in the right place.
Increase debug level to trace7 and check the mod_ssl traces to see what is really going on.
You can do this with LogLevel ssl:trace7
It is a good practice to share the configuration you have within its own context, you can see what you really have, we can't. As in, you could have SSLVerifyClient require in a path and the request going for another and then that directive having no effect, etc.
Also turn "SSLOCSPOverrideResponder off" for these tests.
