I have SSO working with apache responding to a "splunk" cname. But when splunk emails search results the URL is https://hostname:port/... How can I configure splunk to just use a "https://splunk" url so connections will pass through apache?
I solved this problem in my Apache SSO setup - Splunk e-mail alerts contained http://hostname:8000/app/ rather than https://hostname/app/. I was unable to convince Splunk to change its URL, but I was successful in configuring Apache to redirect the broken URLs to the correct location.
First I configured Splunk to listen only on the loopback address in /usr/local/splunk/etc/system/local/web.conf:
server.socket_host = 127.0.0.1
Then I added a VirtualHost to Apache listening on the public IP, port 8000 to redirect to the correct URL. In RHEL/CENTOS' /etc/httpd/conf.d/vhost-splunk-redirect.conf:
