Installation Instructions

Install software requirements

  1. Become ROOT:

    • sudo su -
  2. Change the default mirror with the GARR ones:

    • nano /etc/apt/sources.list
    • CTRL+W (search)
    • CTRL+R (replace)
    • Text to search: 'it.archive.ubuntu.com'
    • Text to replace: 'ubuntu.mirror.garr.it'
    • CTRL+X (save and exit)
    • apt-get update && apt-get upgrade
  3. Install the packages required:

    • apt-get install vim default-jdk ca-certificates openssl apache2 ntp expat
  4. Check that Java is working:

    • update-alternatives --config java

Configure the environment

  1. Modify your /etc/hosts:

    • vim /etc/hosts

      127.0.1.1 idp.example.org idp

    (Replace idp.example.org with your IdP Full Qualified Domain Name)

  2. Be sure that your firewall doesn't block the traffic on port 443 (or you can't access to your IdP)

  3. Define the costant JAVA_HOME and IDP_SRC inside /etc/environment:

    • vim /etc/environment

      JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
      IDP_SRC=/usr/local/src/shibboleth-identity-provider-3.2.1
    • source /etc/environment

    • export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre

    • export IDP_SRC=/usr/local/src/shibboleth-identity-provider-3.2.1

  4. Move the Certificate and the Key file for HTTPS server from /tmp/ to /root/certificates:

    • mkdir /root/certificates
    • mv /tmp/idp-cert-server.crt /root/certificates
    • mv /tmp/idp-key-server.key /root/certificates
    • mv /tmp/DigiCertCA.crt /root/certificates
    • chmod 400 /root/certificates/idp-key-server.key
    • chmod 644 /root/certificates/idp-cert-server.crt
    • chmod 644 /root/certificates/DigiCertCA.crt

    (OPTIONAL) Create a Certificate and a Key self-signed for HTTPS if you don't have the official ones provided by DigiCert:

    • openssl req -x509 -newkey rsa:4096 -keyout /root/certificates/idp-key-server.key -out /root/certificates/idp-cert-server.crt -nodes -days 1095
  5. Configure /etc/default/jetty:

    • update-alternatives --config java (copy the path without /bin/java)

    • update-alternatives --config javac

    • vim /etc/default/jetty

      JETTY_HOME=/usr/local/src/jetty-src
      JETTY_BASE=/opt/jetty
      JETTY_USER=jetty
      JETTY_LOGS=/var/log/jetty
      TMPDIR=/opt/jetty/tmp
      JAVA_OPTIONS="-Djava.awt.headless=true -XX:+DisableExplicitGC -XX:+UseParallelOldGC -Xms256m -Xmx2g -Djava.security.egd=file:/dev/./urandom -Didp.home=/opt/shibboleth-idp"

      (This settings configure the memory of the JVM that will host the IdP Web Application. The Memory value depends on the phisical memory installed on the machine. Set the "Xmx" (max heap space available to the JVM) at least to 2GB)

Install Jetty 9 Web Server

  1. Become ROOT:

    • sudo su -
  2. Download and Extract Jetty:

    • cd /usr/local/src
    • wget http://repo1.maven.org/maven2/org/eclipse/jetty/jetty-distribution/9.3.11.v20160721/jetty-distribution-9.3.11.v20160721.tar.gz
    • tar xzvf jetty-distribution-9.3.11.v20160721.tar.gz
  3. Create an useful-for-updates jetty-src folder:

    • ln -s jetty-distribution-9.3.11.v20160721 jetty-src
  4. Create the user jetty that can run the web server:

    • useradd -r -m jetty
  5. Create your custom Jetty configuration that override the default ones:

    • mkdir /opt/jetty

    • cd /opt/jetty

    • vim /opt/jetty/start.ini

      #===========================================================
      # Jetty Startup
      #
      # Starting Jetty from this {jetty.home} is not recommended.
      #
      # A proper {jetty.base} directory should be configured, instead
      # of making changes to this {jetty.home} directory.
      #
      # See documentation about {jetty.base} at
      # http://www.eclipse.org/jetty/documentation/current/startup.html
      #
      # A demo-base directory has been provided as an example of
      # this sort of setup.
      #
      # $ cd demo-base
      # $ java -jar ../start.jar
      #

  6. Create the TMPDIR directory used by Jetty:

    • mkdir /opt/jetty/tmp ; chown jetty:jetty /opt/jetty/tmp
    • chown -R jetty:jetty /opt/jetty/ /usr/local/src/jetty-src
  7. Create the service loadable from command line:

    • cd /etc/init.d
    • ln -s /usr/local/src/jetty-src/bin/jetty.sh jetty
    • update-rc.d jetty defaults
  8. Create the JETTY_LOG folder:

    • mkdir /var/log/jetty
    • chown jetty:jetty /var/log/jetty
  9. Check if all settings are OK:

    • service jetty check
    • service jetty start

    (If you receive an error likes "Job for jetty.service failed because the control process exited with error code. See "systemctl status jetty.service" and "journalctl -xe" for details.", try this:

    • rm /var/run/jetty.pid
    • service jetty start

Install Shibboleth Identity Provider v3.2.1

  1. Become ROOT:

    • sudo su -
  2. Download the Shibboleth Identity Provider v3.2.1:

    • cd /usr/local/src
    • wget http://shibboleth.net/downloads/identity-provider/3.2.1/shibboleth-identity-provider-3.2.1.tar.gz
    • tar -xzvf shibboleth-identity-provider-3.2.1.tar.gz
    • cd shibboleth-identity-provider-3.2.1
  3. Run the installer install.sh:

    • ./bin/install.sh
    root@idp:/usr/local/src/shibboleth-identity-provider-3.2.1# ./bin/install.sh
    Source (Distribution) Directory: [/usr/local/src/shibboleth-identity-provider-3.2.1]
    Installation Directory: [/opt/shibboleth-idp]
    Hostname: [localhost.localdomain]
    idp.example.org
    SAML EntityID: [https://idp.example.org/idp/shibboleth]
    Attribute Scope: [localdomain]
    example.org
    Backchannel PKCS12 Password: ###PASSWORD-FOR-BACKCHANNEL###
    Re-enter password:           ###PASSWORD-FOR-BACKCHANNEL###
    Cookie Encryption Key Password: ###PASSWORD-FOR-COOKIE-ENCRYPTION###
    Re-enter password:              ###PASSWORD-FOR-COOKIE-ENCRYPTION###

    From this point the variable idp.home refers to the directory: /opt/shibboleth-idp

  4. Import the JST libraries to visualize the IdP status page:

    • cd /opt/shibboleth-idp/edit-webapp/WEB-INF/lib
    • wget https://build.shibboleth.net/nexus/service/local/repositories/thirdparty/content/javax/servlet/jstl/1.2/jstl-1.2.jar
    • cd /opt/shibboleth-idp/bin ; ./build.sh -Didp.target.dir=/opt/shibboleth-idp
  5. Change the owner to enable jetty user to access on the following directories:

    • cd ..
    • chown -R jetty logs/ metadata/ credentials/ conf/ system/ war/

Configuration Instructions

Configure SSL on Apache2 (Jetty front-end)

  1. Modify the file /etc/apache2/sites-available/default-ssl.conf as follows:

    <IfModule mod_ssl.c>
       SSLStaplingCache        shmcb:/var/run/ocsp(128000)
       <VirtualHost _default_:443>
         ServerName idp.example.org:443
         ServerAdmin admin@example.org
         DocumentRoot /var/www/html
         ...
         SSLEngine On
         
         SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
         SSLCipherSuite "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH"
    
         SSLHonorCipherOrder on
    
         # Disable SSL Compression
         SSLCompression Off
         
         # OCSP Stapling, only in httpd/apache >= 2.3.3
         SSLUseStapling          on
         SSLStaplingResponderTimeout 5
         SSLStaplingReturnResponderErrors off
         
         # Enable HTTP Strict Transport Security with a 2 year duration
         Header always set Strict-Transport-Security "max-age=63072000;includeSubDomains;preload"
         ...
         SSLCertificateFile /root/certificates/idp-cert-server.crt
         SSLCertificateKeyFile /root/certificates/idp-key-server.key
         SSLCertificateChainFile /root/certificates/DigiCertCA.pem
         ...
       </VirtualHost>
    </IfModule>
  2. Enable proxy_http, SSL and headers Apache2 modules:

    • a2enmod proxy_http ssl headers alias include negotiation
    • a2ensite default-ssl.conf
    • service apache2 restart
  3. Configure Apache2 to open port 80 only for localhost:

    • vim /etc/apache2/ports.conf

      # If you just change the port or add more ports here, you will likely also
      # have to change the VirtualHost statement in
      # /etc/apache2/sites-enabled/000-default.conf
      
      Listen 127.0.0.1:80
      
      <IfModule ssl_module>
        Listen 443
      </IfModule>
      
      <IfModule mod_gnutls.c>
        Listen 443
      </IfModule>
  4. Configure Apache2 to redirect all on HTTPS:

    • vim /etc/apache2/sites-enabled/000-default.conf
    <VirtualHost *:80>
         ServerName "idp.example.org"
         Redirect "/" "https://idp.example.org/"
    </VirtualHost>
  5. Verify the strength of your IdP's machine on:

Configure Jetty

  1. Become ROOT:

    • sudo su -
  2. Create the Apache2 configuration file for IdP:

    • vim /etc/apache2/sites-available/idp.conf

      <IfModule mod_proxy.c>
          ProxyPreserveHost On
          RequestHeader set X-Forwarded-Proto "https"
          ProxyPass /idp http://localhost:8080/idp retry=5
          ProxyPassReverse /idp http://localhost:8080/idp retry=5
      
          <Location /idp>
             Require all granted
          </Location>
      </IfModule>
  3. Enable the new site:

    • cd /etc/apache2/sites-available/ ; a2ensite idp.conf
    • service apache2 restart
  4. Configure IdP Context Descriptor

    • vim /opt/jetty/webapps/idp.xml

      <Configure class="org.eclipse.jetty.webapp.WebAppContext">
        <Set name="war"><SystemProperty name="idp.home"/>/war/idp.war</Set>
        <Set name="contextPath">/idp</Set>
        <Set name="extractWAR">false</Set>
        <Set name="copyWebDir">false</Set>
        <Set name="copyWebInf">true</Set>
      </Configure>
  5. Restart Jetty:

    • service jetty restart

Configure Shibboleth Identity Provider v3.2.1 to release the persistent-id (Stored mode)

  1. Become ROOT of the machine:

    • sudo su -
  2. Test IdP by opening a terminal and running these commands:

    • cd /opt/shibboleth-idp/bin
    • ./status.sh (You should see some informations about the IdP installed)
  3. Install MySQL Connector Java and other useful libraries used by Jetty for MySQL DB (if you don't have them already):

    • apt-get install mysql-server libmysql-java libcommons-dbcp-java libcommons-pool-java
    • cd /opt/jetty/lib/ext
    • ln -s /usr/share/java/mysql.jar mysql-connector-java.jar
    • ln -s /usr/share/java/commons-pool.jar commons-pool.jar
    • ln -s /usr/share/java/commons-dbcp.jar commons-dbcp.jar
  4. Rebuild the idp.war of Shibboleth with the new libraries:

    • export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
    • cd /opt/shibboleth-idp/bin ; ./build.sh -Didp.target.dir=/opt/shibboleth-idp
  5. Create and prepare the "shibboleth" MySQL DB to host the values of the several persistent-id and StorageRecords MySQL DB to host other useful information about user consent:

    • Modify the shibboleth-db.sql by changing the username and password of the user that has write access to the "shibboleth" DB.

    • Import the SQL modified to your MySQL Server: mysql -u root -p##PASSWORD-DB## < shibboleth-db.sql

    • Restart mysql service: service mysql restart

  6. Enable the generation of the persistent-id (this replace the deprecated attribute eduPersonTargetedID)

    • vim /opt/shibboleth-idp/conf/saml-nameid.properties (the sourceAttribute MUST BE an attribute, or a list of comma-separated attributes, that uniquely identify the subject of the generated persistent-id. It MUST BE: Stable, Permanent and Not-reassignable)

      idp.persistentId.sourceAttribute = uid
      ...
      idp.persistentId.salt = ### result of 'openssl rand -base64 36'###
      ...
      idp.persistentId.generator = shibboleth.StoredPersistentIdGenerator
      ...
      idp.persistentId.dataSource = MyDataSource
      ...
      idp.persistentId.computed = shibboleth.ComputedPersistentIdGenerator
    • Enable the SAML2PersistentGenerator:

      • vim /opt/shibboleth-idp/conf/saml-nameid.xml

        • Remove the comment from the line containing:

          <ref bean="shibboleth.SAML2PersistentGenerator" />
      • vim /opt/shibboleth-idp/conf/c14n/subject-c14n.xml

        • Remove the comment to the bean called "c14n/SAML2Persistent".
  7. Enable JPAStorageService for the StorageService of the user consent:

    • vim /opt/shibboleth-idp/conf/global.xml and add this piece of code to the tail (before </beans> tag):

      <!-- A DataSource bean suitable for use in the idp.persistentId.dataSource property. -->
      <bean id="MyDataSource" class="org.apache.commons.dbcp.BasicDataSource"
            p:driverClassName="com.mysql.jdbc.Driver"
            p:url="jdbc:mysql://localhost:3306/shibboleth?autoReconnect=true"
            p:username="##USER_DB_NAME##"
            p:password="##PASSWORD##"
            p:maxActive="10"
            p:maxIdle="5"
            p:maxWait="15000"
            p:testOnBorrow="true"
            p:validationQuery="select 1"
            p:validationQueryTimeout="5" />
      
      <bean id="shibboleth.JPAStorageService" class="org.opensaml.storage.impl.JPAStorageService"
            p:cleanupInterval="%{idp.storage.cleanupInterval:PT10M}"
            c:factory-ref="shibboleth.JPAStorageService.entityManagerFactory"/>
      
      <bean id="shibboleth.JPAStorageService.entityManagerFactory"
            class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
            <property name="packagesToScan" value="org.opensaml.storage.impl"/>
            <property name="dataSource" ref="MyDataSource"/>
            <property name="jpaVendorAdapter" ref="shibboleth.JPAStorageService.JPAVendorAdapter"/>
            <property name="jpaDialect">
              <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
            </property>
      </bean>
      
      <bean id="shibboleth.JPAStorageService.JPAVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="database" value="MYSQL" />
      </bean>

      (and modify the "##USER_DB_NAME##" and "##PASSWORD##" for your "shibboleth" DB)

    • Modify the IdP configuration file:

      • vim /opt/shibboleth-idp/conf/idp.properties

        idp.consent.StorageService = shibboleth.JPAStorageService
        idp.replayCache.StorageService = shibboleth.JPAStorageService
        idp.artifact.StorageService = shibboleth.JPAStorageService

        (This will indicate to IdP to store the data collected by User Consent into the "StorageRecords" table)

  8. Connect the openLDAP to the IdP to allow the authentication of the users:

    • vim /opt/shibboleth-idp/conf/ldap.properties

      (with TLS solutions we consider to have the LDAP certificate into /opt/shibboleth-idp/credentials).

      • Solution 1: LDAP + STARTTLS:

        idp.authn.LDAP.authenticator = bindSearchAuthenticator
        idp.authn.LDAP.ldapURL = ldap://ldap.example.org:389
        idp.authn.LDAP.useStartTLS = true
        idp.authn.LDAP.useSSL = false
        idp.authn.LDAP.sslConfig = certificateTrust
        idp.authn.LDAP.trustCertificates = %{idp.home}/credentials/ldap-server.crt
        idp.authn.LDAP.baseDN = ou=people,dc=example,dc=org
        idp.authn.LDAP.userFilter = (uid={user})
        idp.authn.LDAP.bindDN = cn=admin,dc=example,dc=org
        idp.authn.LDAP.bindDNCredential = ###LDAP_ADMIN_PASSWORD###
      • Solution 2: LDAP + TLS:

        idp.authn.LDAP.authenticator = bindSearchAuthenticator
        idp.authn.LDAP.ldapURL = ldaps://ldap.example.org:636
        idp.authn.LDAP.useStartTLS = false
        idp.authn.LDAP.useSSL = true
        idp.authn.LDAP.sslConfig = certificateTrust
        idp.authn.LDAP.trustCertificates = %{idp.home}/credentials/ldap-server.crt
        idp.authn.LDAP.baseDN = ou=people,dc=example,dc=org
        idp.authn.LDAP.userFilter = (uid={user})
        idp.authn.LDAP.bindDN = cn=admin,dc=example,dc=org
        idp.authn.LDAP.bindDNCredential = ###LDAP_ADMIN_PASSWORD###
      • Solution 3: plain LDAP

        idp.authn.LDAP.authenticator = bindSearchAuthenticator
        idp.authn.LDAP.ldapURL = ldap://ldap.example.org:389
        idp.authn.LDAP.useStartTLS = false
        idp.authn.LDAP.useSSL = false
        idp.authn.LDAP.baseDN = ou=people,dc=example,dc=org
        idp.authn.LDAP.userFilter = (uid={user})
        idp.authn.LDAP.bindDN = cn=admin,dc=example,dc=org
        idp.authn.LDAP.bindDNCredential = ###LDAP_ADMIN_PASSWORD###

        (If you decide to use the Solution 3, you have to remove (or comment out) the following code from your Attribute Resolver file:

        UTILITY FOR OPENLDAP ADMINISTRATOR:

        • ldapsearch -H ldap:// -x -b "dc=example,dc=it" -LLL dn
          • the baseDN ==> ou=people, dc=example,dc=org (branch containing the registered users)
          • the bindDN ==> cn=admin,dc=example,dc=org (distinguished name for the user that can made queries on the LDAP)
  9. Enrich IDP logs with the authentication error occurred on LDAP:

    • vim /opt/shibboleth-idp/conf/logback.xml

      <!-- Logs LDAP related messages -->
      <logger name="org.ldaptive" level="${idp.loglevel.ldap:-WARN}"/>
      
      <!-- Logs on LDAP user authentication -->
      <logger name="org.ldaptive.auth.Authenticator" level="INFO" />
  10. Define which attributes your IdP can manage into your Attribute Resolver file. Here you can find the attribute-resolver-v3-idem.xml provided by IDEM GARR AAI as example:

    • Download the attribute resolver provided by IDEM GARR AAI: wget http://www.garr.it/idem-conf/attribute-resolver-v3-idem.xml -O /opt/shibboleth-idp/conf/attribute-resolver-v3-idem.xml

    • Modify services.xml file: vim /opt/shibboleth-idp/conf/services.xml

      <value>%{idp.home}/conf/attribute-resolver.xml</value>

      must become:

      <value>%{idp.home}/conf/attribute-resolver-v3-idem.xml</value>
  • Configure the LDAP Data Connector to be compliant to the values put in ldap.properties. (See above suggestions)
  1. Translate the IdP messages in your language:

    • Get the files translated in your language from Shibboleth page for:
      • login page (authn-messages_it.properties)
      • user consent/terms of use page (consent-messages_it.properties)
      • error pages (error-messages_it.properties)
    • Put all downloaded files into /opt/shibboleth-idp/messages directory
    • Restart Jetty: service jetty restart
  2. Enable the SAML2 support by changing the idp-metadata.xml and disabling the SAML v1.x deprecated support:

    • vim /opt/shibboleth-idp/metadata/idp-metadata.xml
      <IDPSSODescriptor> SECTION:

  3. Obtain your IdP metadata here:

    • https://idp.example.org/idp/shibboleth
  4. Register you IdP on IDEM Entity Registry (your entity have to be approved by an IDEM Federation Operator before become part of IDEM Test Federation):

    • https://registry.idem.garr.it/
  5. Configure the IdP to retrieve the Federation Metadata:

    • cd /opt/shibboleth-idp/conf

    • vim metadata-providers.xml

            xsi:type="FileBackedHTTPMetadataProvider"
            backingFile="%{idp.home}/metadata/idem-test-metadata-sha256.xml"
            metadataURL="http://md.idem.garr.it/metadata/idem-test-metadata-sha256.xml">
      
            <!--
                Verify the signature on the root element of the metadata aggregate
                using a trusted metadata signing certificate.
            -->
            <MetadataFilter xsi:type="SignatureValidation" requireSignedRoot="true" certificateFile="${idp.home}/metadata/federation-cert.pem"/>
      
            <!--
                Require a validUntil XML attribute on the root element and
                make sure its value is no more than 10 days into the future.
            -->
            <MetadataFilter xsi:type="RequiredValidUntil" maxValidityInterval="P10D"/>
      
            <!-- Consume all SP metadata in the aggregate -->
            <MetadataFilter xsi:type="EntityRoleWhiteList">
              <RetainedRole>md:SPSSODescriptor</RetainedRole>
            </MetadataFilter>
      </MetadataProvider>
    • Retrieve the Federation Certificate used to verify its signed metadata:

      • wget https://md.idem.garr.it/certs/idem-signer-20220121.pem -O /opt/shibboleth-idp/metadata/federation-cert.pem
    • Check the validity:

      • cd /opt/shibboleth-idp/metadata

      • openssl x509 -in federation-cert.pem -fingerprint -sha1 -noout

        (sha1: D1:68:6C:32:A4:E3:D4:FE:47:17:58:E7:15:FC:77:A8:44:D8:40:4D)

      • openssl x509 -in federation-cert.pem -fingerprint -md5 -noout

        (md5: 48:3B:EE:27:0C:88:5D:A3:E7:0B:7C:74:9D:24:24:E0)

  6. Reload service with id shibboleth.MetadataResolverService to retrieve the Federation Metadata:

    • cd /opt/shibboleth-idp/bin
    • ./reload-service.sh -id shibboleth.MetadataResolverService
  7. The day after the IDEM Federation Operators approval your entity on IDEM Entity Registry, check if you can login with your IdP on the following services:

        - Remove all ":8443" from the existing URL (such port is not used anymore)
  5. Restart Jetty:

    • service jetty restart
  6. Don't forget to update your IdP Metadata on IDEM Entity Registry to apply changes on the federation IDEM! For any help write to idem-help@garr.it

Appendix B: Import persistent-id from a previous database

  1. Create a DUMP of shibpid table from the previous DB userdb on the OLD IdP:

    • cd /tmp
    • mysqldump --complete-insert --no-create-db --no-create-info -u root -p userdb shibpid > /tmp/userdb_shibpid.sql
  2. Move the /tmp/userdb_shibpid.sql of old IdP into /tmp/userdb_shibpid.sql on the new IdP.

  3. Import the content of /tmp/userdb_shibpid.sql into the DB of the new IDP:

    • cd /tmp ; mysql -u root -p shibboleth < /tmp/userdb_shibpid.sql
  4. Delete /tmp/userdb_shibpid.sql:

    • rm /tmp/userdb_shibpid.sql

Appendix C: Useful logs to find problems

  1. Jetty Logs:

    • cd /opt/jetty/logs
    • ls -l *.stderrout.log
  2. Shibboleth IdP Logs:

    • cd /opt/shibboleth-idp/logs
    • Audit Log: vim idp-audit.log
    • Consent Log: vim idp-consent-audit.log
    • Warn Log: vim idp-warn.log
    • Process Log: vim idp-process.log

Appendix D: Issues

  1. The <ResultCache>, an LDAP Data Connector child element, in IdP versions before 3.3.0 has a serious security issue, as described in security advisory 20161027.

If you are using a vulnerable version of the IdP then you should not use this element in new deployments, and you should remove it from existing deployments.

The element can be used safely starting with IdP version 3.3.0.
