When Identity runs in
apache-httpd, you can use external
authentication methods that differ from the authentication provided by
the identity store back end. For example, you can use an SQL identity
back end together with X.509 authentication and Kerberos, instead of
using the user name and password combination.
Web servers, like Apache HTTP, support many methods of authentication.
Identity can allow the web server to perform the authentication. The web
server then passes the authenticated user to Identity by using the
REMOTE_USER environment variable. This user must already exist in
the Identity back end to get a token from the controller. To use this
method, Identity should run on
The following Apache configuration snippet authenticates the user based on a valid X.509 certificate from a known CA:
<VirtualHost _default_:5000> SSLEngine on SSLCertificateFile /etc/ssl/certs/ssl.cert SSLCertificateKeyFile /etc/ssl/private/ssl.key SSLCACertificatePath /etc/ssl/allowed_cas SSLCARevocationPath /etc/ssl/allowed_cas SSLUserName SSL_CLIENT_S_DN_CN SSLVerifyClient require SSLVerifyDepth 10 (...) </VirtualHost>
