Subject [users@httpd] Problem with Apache 2.2.13 and "SSLOptions +FakeBasicAuth"
Date Sat, 12 Sep 2009 21:39:45 GMT

We are using Apache as a reverse-proxy in front of a WebLogic server.

In our older configuration, using Apache 2.0.5x, when we enable client-authenticated SSL,
and uncomment the following line in ssl.conf:

SSLOptions +FakeBasicAuth +ExportCertData +CompatEnvVars +StrictRequire

we get the "Authorization" HTTP header, containing the BASE64-encoded certificate subject
string (actually, <cert subject string>:password, BASE64-encoded).

We are now moving to Apache 2.2.x, and I'm testing a configuration on Windows, and it looks
like, when we uncomment the SSLOptions line in extra/httpd-ssl.conf, the "Authorization" HTTP
header is no longer being sent by Apache to WebLogic.

I also tried changing the SSLOptions directive to just:

SSLOptions +FakeBasicAuth

and I still don't see the "Authorization" header.

According to the docs:

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:

Does anyone know why I might not be getting the "Authorization" HTTP header, or, more importantly,
how I can get that working again?
