= Shibboleth IdP v3.3.2 on Ubuntu Linux LTS 18.04 = Installation assumes you have already installed Ubuntu Server 18.04 with default configuration and has a public IP connectivity with DNS setup Lets Assume your server hostname as '''idp.instXY.ac.lk''' All commands are to be run as root and you may use `sudo su` to become root 1. Install the packages required: {{{ apt-get install vim default-jdk ca-certificates openssl tomcat8 apache2 ntp expat }}} 2. Add to or Modify `/etc/hosts`: {{{ vim /etc/hosts }}} {{{ 127.0.0.1 idp.instXY.ac.lk idp }}} (Replace `idp.instXY.ac.lk` with your IdP FQDN) 3. Define the costants `JAVA_HOME` and `IDP_SRC` inside `/etc/environment`: * {{{ update-alternatives --config java }}} (copy the path without /bin/java) * {{{ vim /etc/environment }}} {{{ JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 IDP_SRC=/usr/local/src/shibboleth-identity-provider-3.3.2 }}} * {{{ source /etc/environment }}} * {{{ export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64 }}} * {{{ export IDP_SRC=/usr/local/src/shibboleth-identity-provider-3.3.2 }}} 4.

It is recommand to customize this page to have the proper institution logo and name. To give a consistent professional look, institution may customize the graphics to match the style of their, * login pages * onsent pages * logout pages * error pages Those pages are created as Velocity template under `/opt/shibboleth-idp/views` Therefore, it is recommended to customize the Velocity pages, adding supplementary images and CSS files as needed Also the Velocity templates can be configured through message properties defined in message property files on `/opt/shibboleth-idp/system/messages/messages.properties` '''which should NOT be modified''' because of that, any customizations should be inserted into `/opt/shibboleth-idp/messages/messages.properties` least configurations: `idp.title` - HTML TITLE to use across all of the IdP page templates. We recommend settings this to something like University of Example Login Service `idp.logo` - relative path to the logo to render on the templates. E.g., /images/logo.jpg. The logo image has to be installed into /opt/shibboleth-idp/edit-webapp/images and the web application WAR file has to be rebuilt with /opt/shibboleth-idp/bin/build.sh `idp.logo.alt-text` - the ALT text for your logo. Should be changed from the default value (where the text asks for the logo to be replaced). `idp.footer` - footer that displays on (almost) all pages. `root.footer` - footer that displays on some error pages. Eg: {{{ idp.title = University of Example Login Service idp.logo = /images/logo.jpg idp.logo.alt-text = University of Example logo idp.footer = Copyright University of Example root.footer = Copyright University of Example }}} Depending on branding requirements, it may be sufficient to edit the CSS files in /opt/shibboleth-idp/edit-webapp/css, or it may be necessary to start editing the template pages. Please note that the login page and most other pages use /opt/shibboleth-idp/edit-webapp/css/main.css, the consent module uses /opt/shibboleth-idp/edit-webapp/css/consent.css with different element names. Besides the logo, the login page (and several other pages) display a toolbox on the right with placeholders for links to password-reset and help-desk pages, these can be customized by adding following to the `/opt/shibboleth-idp/messages/messages.properties` {{{ idp.url.password.reset = http://helpdesk.instXY.ac.lk/ChangePassword/ idp.url.helpdesk = http://help.instXY.ac.lk/ }}} Alternatively, it is also possible to hide the whole toolbox (the whole element) from all of the relevant pages (essentially, login.vm and all (three) logout pages: logout.vm, logout-complete.vm and logout.propagate). This can be easily done by adding the following CSS snippet into /opt/shibboleth-idp/edit-webapp/css/main.css: {{{ .column.two { display: none; } }}} For your simplisity in developing, temporary add the following to Apache idp.conf file ( /etc/apache2/sites-available/idp.conf ) to server the requests directly by Apache (avoiding going through Tomcat and thus avoiding having to rebuild the WAR file after every change):insert the following right above the '''ProxyPass /idp''' directive: {{{ ProxyPass /idp/images ! ProxyPass /idp/css ! Alias /idp/images /opt/shibboleth-idp/edit-webapp/images Alias /idp/css /opt/shibboleth-idp/edit-webapp/css }}} And, as default permissions on Apache 2.4 are more restrictive, grant also explicitly access to the /opt/shibboleth-idp/edit-webapp directory: insert this at the very top of /etc/httpd/conf.d/idp.conf: {{{ Require all granted }}} When done with changes to the images and css directories, remember to rebuild the WAR file and restart Tomcat: {{{ /opt/shibboleth-idp/bin/build.sh service tomcat restart }}} Then remove the temporary additions on idp.conf and restart the apache service. == Appendix: Useful logs to find problems == 1.
