Introduction
|
|
============
|
|
|
|
IdPC is an implementation of a `Liberty Alliance`_ Identity Provider in the form
|
|
of several CGI C programs.
|
|
|
|
It supports the following IDFF-1.2 profiles:
|
|
|
|
- Single Sign-On and Federation (Liberty Artifact and Liberty-Enabled Client
|
|
and Proxy)
|
|
- Single Logout (SOAP, initiated by SP)
|
|
- Federation Termination (SOAP, initiated by SP)
|
|
|
|
It will complete existing profiles and implement other core profiles in the
|
|
future.
|
|
|
|
IdPC can authenticate users through several means including HTTP authentication
|
|
and client certificates.
|
|
|
|
|
|
Download
|
|
========
|
|
|
|
IdPC releases can be downloaded from
|
|
http://labs.libre-entreprise.org/project/showfiles.php?group_id=55
|
|
|
|
Development code is available using CVS::
|
|
|
|
export CVSROOT=:pserver:anonymous@cvs.labs.libre-entreprise.org:/cvsroot/idpc
|
|
cvs login # press enter
|
|
cvs -z3 checkout idpc
|
|

.. _INSTALL:
|
|
.. include:: ../INSTALL

IdPC Configuration
|
|
==================
|
|
|
|
IdPC needs a configuration file to work; its location depends of compilation
|
|
options; IdPC will tell you the correct path if you call one of the CGI with
|
|
the ``--help`` argument::
|
|
|
|
$ /usr/lib/cgi-bin/idpc/soapEndpoint --help
|
|
This is IdPC; it is meant to be used as a CGI
|
|
|
|
Config file should be installed as:
|
|
/etc/idpc/config.xml
|
|
|
|
The configuration file must be a valid XML file and its root element should be
|
|
named "idpc" and placed in the following namespace
|
|
``http://www.entrouvert.org/namespaces/idpc``.
|
|
|
|
metadataFilePath:
|
|
path to the Liberty Alliance IdP metadata file
|
|
|
|
idpPublicKey:
|
|
path to the IdP public key (PEM encoded)
|
|
|
|
idpPrivateKey:
|
|
path to the IdP private key (PEM encoded)
|
|
|
|
idpCertificate:
|
|
path to the IdP certificate (PEM encoded) (?)
|
|
|
|
serviceProvider:
|
|
element that should contains three other elements; metadataFilePath,
|
|
spPublicKey and spCaCertificate. You can of course have more than one
|
|
<serviceProvider> element.
|
|
|
|
authenticationMethod:
|
|
authentication method to use, detailed below
|
|
|
|
reauthenticationDelay:
|
|
The time at, or after which the service provider must reauthenticate
|
|
the user against the IdP. (in seconds) (default is 7200, 2 hours)
|
|
|
|
dbhost:
|
|
hostname where the IdPC database is installed (optional)
|
|
|
|
dbport:
|
|
port where the IdPC database is listening (optional)
|
|
|
|
dbname:
|
|
name of the IdPC database
|
|
|
|
dblogin:
|
|
login to connect to the IdPC database
|
|
|
|
dbpassword:
|
|
password to connect to the IdPC database
|
|
|
|
ocspUrl:
|
|
URL to the OCSP service for certificate validation (optional)
|
|
|
|
ocspIssuer:
|
|
path to the OCSP issuer certificate (PEM encoded)
|
|
|
|
|
|
Authentication Methods
|
|
----------------------
|
|
|
|
HTTP authentication
|
|
```````````````````
|
|
|
|
Keyword: ``http``
|
|
|
|
HTTP authentication is handled by the web server; it should pass a REMOTE_USER
|
|
environment variable to the CGI. Apache allows many sources for HTTP
|
|
authentication including LDAP directory and PostgreSQL and MySQL databases.
|
|
|
|
The REMOTE_USER will be used as key to identify users in the database.
|
|
|
|
Certificate authentication
|
|
``````````````````````````
|
|
|
|
Keyword: ``certificate``
|
|
|
|
This authentication relies on Apache ``mod_ssl`` to set several environment
|
|
variables; your Apache configuration must contains a ``SSLVerifyClient``
|
|
option with ``optional`` or ``require`` as value.
|
|
|
|
The certificate serial will be used as key to identify users in the database.
|
|
|
|
.. note:: (this is subject to change)
|
|
|
|
Additionally if you have set OCSP options in the configuration file, a OCSP
|
|
connection will be made to check certificate validity.
|
|
|
|
|
|
Apache Configuration
|
|
====================
|
|
|
|
Imagine ``soapEndPoint`` has been installed in ``/usr/lib/cgi-bin/idpc/`` and
|
|
``singleSignOn`` in ``/usr/lib/cgi-bin/idpc/auth/``. Apache configuration will
|
|
look as follow::
|
|
|
|
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
|
|
|
|
<Directory /usr/lib/cgi-bin/>
|
|
AllowOverride None
|
|
Options ExecCGI -MultiViews +SymLinksIfOwnerMatch
|
|
Order allow,deny
|
|
Allow from all
|
|
</Directory>
|
|
|
|
<Directory /usr/lib/cgi-bin/idpc/auth>
|
|
AuthType Basic
|
|
AuthName "IdPc"
|
|
AuthUserFile /etc/apache/passwd
|
|
Require valid-user
|
|
</Directory>
|
|
|
|
|
|
Database configuration
|
|
======================
|
|
|
|
PostgreSQL
|
|
----------
|
|
|
|
.. include:: ../create-db.sql
|
|
|
|
Be sure it is possible to connect using TCP/IP to the database; somethink like
|
|
the next line will do (you may have to disable ``ident`` authentication first)::
|
|
|
|
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
|
|
host idpc idpc 127.0.0.1 255.255.255.255 password
|
|
|
|
|
|
MySQL
