+
+Above snippet defines two service providers for shibboleth under two different entity id's. 
+
+Default application as {{{ entityID="https://wp.Your-Domain/shibboleth" }}} and the second as an override with id mdl {{{ <ApplicationOverride id="mdl" entityID="https://mdl.Your-Domain/shibboleth"> }}}
+
+Both entities will have common features like metadata providers, attribute maps. But they will have two different certificate sets.
+
+Now lets create those certificate pairs.
+
+* {{{ /usr/sbin/shib-keygen -n wp-signing -e https://wp.YOUR-DOMAIN/shibboleth }}}
+* {{{ /usr/sbin/shib-keygen -n wp-encrypt -e https://wp.YOUR-DOMAIN/shibboleth }}}
+* {{{ /usr/sbin/shib-keygen -n mdl-signing -e https://mdl.YOUR-DOMAIN/shibboleth }}}
+* {{{ /usr/sbin/shib-keygen -n mdl-encrypt -e https://mdl.YOUR-DOMAIN/shibboleth }}}
+
+Then check the shibboleth configuration for errors by, 
+
+{{{ shibd -t /etc/shibboleth/shibboleth2.xml }}}
+
+Next, enable apache shibboleth module and restart apache.
+
+{{{
+#!bash
+    a2enmod shib2
+    systemctl reload apache2.service
+}}}
