shibboleth_django-freeradius_login

This project implements a JAAS LoginModule of Java which permits a Shibboleth idp server to authenticate with the module django-freeradius.

Requirements

This project works with a Shibboleth idp server and django-freeradius module, so see the following links for the documentations:

Furthermore, this module use the Unirest library so it's necessary have a .jar file of this. See this page for generate it from the library: install unirest-java.

Seup

Clone the repository of the project in the /usr/local/src folder of the Shibboleth idp server:

git clone https://github.com/AlessiaVe/shibboleth_django-freeradius_login.git

Move into the sources directory:

cd shibboleth_django-freeradius_login/src/Django/jaas

jaas.config

Open the file /conf/authn/password_authn_config.xml, and modify as following:

 <import resource="jaas-authn-config.xml">
 <!-- <import resource="krb5-authn-config.xml" /> -->
 <!-- <import resource="ldap-authn-config.xml" /> -->

to disable ldap authenticator and enable jaas authenticator.

Create or replace the file jaas.config under /conf/authn use the following content:

ShibUserPassAuth {
 Django.jaas.DjangoLoginModule sufficient
   djangoUrl="http://ip:port/api/authorize/";
};

This file sets up the DjangoLoginModule as sufficient for the authentication of the user. The option djangoUrl is the url of the Django REST framework to the authorize page:

ip is the ip of the machine where there is the django server;
port is the port where we have set up the REST interface of Django.

Unirest library

After generate the .jar file, raname it like unirest.jar and copy it in the src folder.

Build the project

This code has to be compiled and moved to the principal directory of the Java enviroment. So I suggest to use a build.sh in the src folder to do it automatically. The file is like the following, please adjust JAVA_HOME and Shibboleth installation folder according to your environment:

JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/jre
SHIBBOLETH_FOLDER=/opt/shibboleth-idp

cp unirest.jar              $JAVA_HOME/lib/ext/

javac -cp unirest.jar DjangoLoginModule.java
javac DjangoPrincipal.java
jar cvf Django.jar *.class

cp Django.jar               $JAVA_HOME/lib/ext/

This file copies the unirest.jar into the JAVA_HOME directory, compiles the two java files with the dependency and copies the jar files into the JAVA_HOME.

Run the project

To start use the module run the build.sh file with:

./build.sh

and restart Tomcat or Jetty.

After that, the idp authenticates only the Django users. Hope you enjoy!
