Why don't you show us what you're doing?

The docs (http://httpd.apache.org/docs-2.0/mod/mod_ssl.html) say that

    SSLOptions +FakeBasicAuth

..." When this option is enabled, the Subject Distinguished Name (DN)
of the Client X509 Certificate is translated into a HTTP Basic
Authorization username. This means that the standard Apache
authentication methods can be used for access control. The user name
is just the Subject of the Client's X509 Certificate (can be
determined by running OpenSSL's openssl x509 command: openssl x509
-noout -subject -in certificate.crt). Note that no password is
obtained from the user. Every entry in the user file needs this
password: ``xxj31ZMTZzkVA'', which is the DES-encrypted version of the
  word `password''. Those who live under MD5-based encryption (for
instance under FreeBSD or BSD/OS, etc.) should use the following MD5
hash of the same word: ``$1$OXLyS...$Owx8s2/m9/gfkcRVXzgoE/''".

Sounds like you'll need a password file.
