The installation instructions provided in this guide are specific to a deployment without Apache httpd, using Apache Tomcat both as Java Servlet Container and as TLS/SSL-enabled webserver. Do not follow these installtion instructions if you're determined to use Apache
httpd (which is also possible, but sufficiently documented elsewhere) – though you can still follow the rest of our documentation (for metadata, resolver, filter, etc. configuration).
There is no point in duplicating the existing Shibboleth IDP 3.x documentation. The installation part of this guide is complete but the guide for configuration of a Shibboleth IDP is necessarily incomplete, as deployments can vary significantly and the IDPv3 has tons of (optional) advanced features. Please use the upstream documentation for further steps or more advanced configurations, as hinted at below.
Until more steps/topics are covered in the instructions in this wiki please refer to the upstream documentation and engage with the community:
