+Mod_auth_kerb is an Apache module designed to provide Kerberos
+authentication to the Apache web server. The module also supports
+the Negotiate authentication method, which performs full Kerberos
+authentication based on ticket exchanges, and does not require
+users to insert their passwords to the browser.
+
+This requires heimdal.
+
+You will need to add the following line to /etc/httpd/httpd.conf:
+  Include /etc/httpd/extra/mod_auth_kerb.conf
+
+Mod_auth_kerb can be further configured through the Apache configuration
+file; see the README in the package's documentation directory for details.
