Following document instructs how to install Shibbolized Tiqr (or "tiqrshib") in the IdP environment. Please feel free to contact us (tiqr at meatmail.jp) if you have any difficulty while installing thisduring installation.

About Enviroment

This instruction is for Shibbolized Tiqr 2.2. Shibbolized Tiqr is tested under the following environment.

• CentOS 7.35
• httpd 2.4
• PHP 5.4
• Oracle JDK 1.8
• Apache Maven 3.2
• Tomcat 89.0
• Shibboleth IdP 3.34.10
• Shibboleth SP 23.60

This document assumes Shibboleth IdP and SP are configured and ready for SAML SSO; IdP should be able to authenticate users per SP's authn request, and supply users' attributes back to SP appropriately. Some attributes must be supplied to SP because Shibbolized Tiqr implicitly requires them:

...

This document assumes they are installed based on the following document provided by GakuNin. If you installed them in a different way, consider modifying some of our proceduresmodify the procedure below as your system requires.

Installation

Install

...

Dependent Yum Packages

To install depending packages, run the following command:

...

Here, sqlite is installed as our sample configuration requires it. If you want to use MySQL for the backend DB, consider installing "mysql-connector-odbc" and "php-mysql" instead.

Deploy "tiqrzend" server

...

Checkout Source Code for Shibbolized Tiqr

Checkout the source code from the repository.

...

It should contain two projects, "tiqrzend" and the Shibboleth IdP extension. Here  

Deploy "tiqrzend" server

 Here we setup "tiqrzend" first.

...

$ mkdir -p /opt/tiqrzend/db/
$ sqlite3 /opt/tiqrzend/db/secrets.db
sqlite> CREATE TABLE IF NOT EXISTS tiqrshibsecrets (
...> `id` integer NOT NULL PRIMARY KEY AUTOINCREMENT,
...> `uid` text NOT NULL UNIQUE,
...> `secret` text DEFAULT NULL,
...> `isActive` integer DEFAULT NULL);
sqlite> (exit)
$ sudo chown -R ,
...> `loginattempts` integer DEFAULT NULL,
...> `isBlocked` integer DEFAULT NULL);
sqlite> (exit)
$ sudo chown -R apache: /opt/tiqrzend/db
$ sudo chmod -R go-rwx /opt/tiqrzend/db

Configure httpd

Modify /etc/httpd/conf.d/ssl.conf (or whatever httpd config file you prefer) so httpd contain the following settings:

Alias /tiqr/ "/opt/tiqrzend/public/"
<Location /tiqr>
  RewriteEngine On
  RewriteBase /tiqr
  RewriteCond %{REQUEST_FILENAME} -s [OR]
  RewriteCond %{REQUEST_FILENAME} -l [OR]
  RewriteCond %{REQUEST_FILENAME} -d
  RewriteRule ^.*$ - [NC,L]
  RewriteRule ^.*$ /tiqr/index.php [NC,L]
  require all granted
</Location>
<Location /tiqr/shib/enroll/process>
  AuthType shibboleth
  ShibRequestSetting requireSession 1
  require valid-user
</Location>

Confirm "tiqrzend

...

" is Working

With the modifications above, tiqr authentication flow should be ready for evaluation.

...

What you should check here is if the redirect happens at this point. If the redirect does not happen and some other problem happens, you will need to trouble-shoot it here.

Checking "tiqrzend

...

" Log

There are multiple logs to be checked when there are some errors.

• httpd's logs in /var/log/httpd
• PHP's logs in syslog or whatever you configured at /etc/php.ini
• tiqrzend's login logs /opt/tiqrzend/application/logs/

Deploy the Shibboleth IdP extension

Build the

...

Extension

Building the IdP extension requires Apache Maven. You can build the extension outside where IdP resides, but you need the same Java environment to build the extenion extension there.

Here is how to install Apache Maven 3.5.0 in /opt/ directory.

...

$ ls
pom.xml  src
$ mvn -DskipTests=false clean package
... (a lot of logs) ...
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------
[INFO] Total time: 1.683 s
[INFO] Finished at: 2017-09-05T16:41:39+09:00
[INFO] Final Memory: 24M/361M
[INFO] ------------------------------------------------------------------------
$ ls
pom.xml  src  target
$ ls target/
classes  maven-archiver  tiqrshibauthn-2.02.jar

Here, tiqrshibauthn-2.0x.jar in target/ is what we want.

If you are outside the host where IdP resides, copy the jar file to the server.

Install the

...

Extension into

...

Shibboleth IdP

From this step, we assume you logged in the host where IdP resides as root. You should also prepare IdP's installation package unpacked somewhere.

...

...

# pwd
/root/shibboleth-identity-provider-3.3.1

Before going forward, we recommend to stop Tomcat.

# systemctl stop tomcat

Place tiqrshibauthn-2.0x.jar in IdP installer's /opt/shibboleth-idp/edit-webapp/WEB-INF/lib/ directory.

<servlet>
#   cp <servlet-name>TiqrShibAuthnHandler</servlet-name>
    <servlet-class>jp.gakunin.tiqrshib.TiqrShibAuthnServlet</servlet-class>
    <load-on-startup>4</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>TiqrShibAuthnHandler</servlet-name>
    <url-pattern>/Authn/TiqrShib</url-pattern>
</servlet-mapping>

Install the modified IdP using bin/install.sh as usual IdP installation.

# bin/install.sh

Depending on your Tomcat configuration, you may need to copy `idp.war` in `/usr/java/tomcat/webapps/` and remove `idp/` directory there.

# cp -f /opt/shibboleth-idp/war/idp.war /usr/java/tomcat/webapps/
# rm -rf /usr/java/tomcat/webapps/idp

If you choose to run Tomcat under the user "tomcat", you may also need to review directory permissions in /opt/shibboleth-idp/ again.

# chown -R tomcat:tomcat /opt/shibboleth-idp/logs
# chgrp -R tomcat /opt/shibboleth-idp/conf
# chmod -R g+r /opt/shibboleth-idp/conf
# find /opt/shibboleth-idp/conf -type d -exec chmod -R g+s {} \;
# chgrp tomcat /opt/shibboleth-idp/metadata
# chmod g+w /opt/shibboleth-idp/metadata
# chmod +t /opt/shibboleth-idp/metadata

...

-i .../tiqrshibauthn-2.?.jar /opt/shibboleth-idp/edit-webapp/WEB-INF/lib/

Add the following XML content in `/opt/shibboleth-idp/edit-webapp/WEB-INF/web.xml`. If you don't have the web.xml file, copy from `/opt/shibboleth-idp/webapp/WEB-INF/web.xml` in advance.

<servlet>
    <servlet-name>TiqrShibAuthnHandler</servlet-name>
    <servlet-class>jp.gakunin.tiqrshib.TiqrShibAuthnServlet</servlet-class>
    <load-on-startup>4</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>TiqrShibAuthnHandler</servlet-name>
    <url-pattern>/Authn/TiqrShib</url-pattern>
</servlet-mapping>

Rebuild the modified IdP WAR package using bin/build.sh.

# bin/build.sh

Depending on your Tomcat configuration, you may need to copy `idp.war` in `$CATALINA_BASE/webapps/` and remove `idp/` directory there.

# cp -f /opt/shibboleth-idp/war/idp.war $CATALINA_BASE/webapps/
# rm -rf $CATALINA_BASE/webapps/idp

Also depending on your Tomcat version, you may need to remove temporary files.

# rm -r $CATALINA_BASE/webapps/idp $CATALINA_BASE/work/Catalina/localhost/idp

Configure IdP for the Extension

Move to `/opt/shibboleth-idp/` and modify relevant configuration files.

...

Create `flows/authn/tiqrshib/` directory and copy some relevante relevant XML files. Then edit copied files so they become ready for tiqrshib authentication.

...

<bean id="authn/tiqrshib" parent="shibboleth.AuthenticationFlow"
    p:nonBrowserSupported="false">
    <property name="supportedPrincipals">
        <list>
            <bean parent="shibboleth.SAML2AuthnContextClassRef        <bean parent="shibboleth.SAML2AuthnContextClassRef"
                c:classRef="urn:oasis:names:tc:SAML:2.0:ac:classes:MobileTwoFactorUnregistered" />
        </list>
    </property>
</bean>

You probably want to modify `classRef` settings, depending on what authnContext you want to use for the tiqrshib authn.

Modify `conf/idp.properties` so `idp.authn.flows` contain "tiqrshib"

idp.authn.flows=Password|tiqrshib

Add sessionCookiePath="/" in Context element in `$CATALINA_BASE/conf/Catalina/localhost/idp.xml` in order to be able to check JSESSIONID in PHP side. E.g.:

<Context docBase="/opt/shibboleth-idp/war/idp.war"
                c:classRef="urn:oasis:names:tc:SAML:2.0:ac:classes:MobileTwoFactorUnregistered" />
   privileged="true"
         </list>antiResourceLocking="false"
    </property>
</bean>

You probably want to modify `classRef` settings, depending on what authnContext you want to use for the tiqrshib authn.

Modify `conf/idp.properties` so `idp.authn.flows` contain "tiqrshib"

idp.authn.flows=Password|tiqrshib     swallowOutput="true"
         sessionCookiePath="/">

...
</Context>

Finally, start Tomcat.

# systemctl start tomcat

...

<Location /shibtiqr_protected>
    AuthType shibboleth
    ShibRequestSetting requireSession 1
    ShibRequestSetting authnContextClassRef urn:oasis:names:tc:SAML:2.0:ac:classes:MobileTwoFactorUnregistered
    Require valid-user
</Location>

...

Configuration

Now that you confirmed Shibbolized Tiqr works on your server, we recommend reviewing your tiqrshib settings. Check your application.ini and review your settings. If you copied it from application.example.ini, you will see prenty of comments that describe each configuration and some recommendations.

...

Change secrets shared between tiqrzend and the IdP extentionextension.

• On tiqrzend side, modify resources.tiqrshib.encryption.key and resources.tiqrshib.encryption.iv.
• On the extension side, modify AES_KEY and AES_IV in TiqrShibConstants.java in the IdP extension.

Note that the modification requires recreating jar file and IdP package re-installationbuild.

Metadata for Tiqr Server

...

• resources.tiqr.identifier
• resources.tiqr.name
• resources.tiqr.logoUrl

Consult to the officitial official document (https://tiqr.org/tiqr-simplesaml-integration-guide) for more information.

...

You may want some redundancy or possibly more performance, in which case consider using MySQL instead of SQLite3. There are descriptions in the example config how to achieve it.
