Hi, I am setting up a new ftp server, which is pureftpd on my linux machine. I am trying to setup a dual ssl certificate authentication with it. I have been successful in setting up a server certificate and client gets to view and verify it. However, i would also like the client to verify itself to the server. For this, i would like to enable REQUIRE_VALID_CLIENT_CERTIFICATE macro in pureftpd configuration. I tried changing the "config.h.in" and configured pureftpd, this reflected the changes in config.h file. However, when i try to start pureftpd with "-Y 2" option (enabling ssl/tls), pureftpd doesn't start. Could you suggest, how exactly REQUIRE_VALID_CLIENT_CERTIFICATE macro is to be enabled ?
