Setup Shibboleth
Federate Keystone (SP) and an external IdP.
Once you have your Keystone vhost (virtual host) ready, it's then time to configure Shibboleth and upload your Metadata to the Identity Provider.
If new certificates are required, they can be easily created by executing:
$ shib-keygen -y <number of years>
The newly created file will be stored under
/etc/shibboleth/sp-key.pem
You should fetch your Service Provider's Metadata file. Typically this can be achieved by simply fetching a Metadata file, for example:
$ wget --no-check-certificate -O <name of the file> https://service.example.org/Shibboleth.sso/Metadata
Upload your Service Provider's Metadata file to your Identity Provider. This step depends on your Identity Provider choice and is not covered here.
Configure your Service Provider by editing
/etc/shibboleth/shibboleth2.xml
file. You are advised to
examine Shibboleth
Service Provider Configuration documentation
An example of your /etc/shibboleth/shibboleth2.xml
may

Keystone enforces external
authentication when environment variable REMOTE_USER
is
present so make sure Shibboleth doesn't set the REMOTE_USER
environment variable. To do so, scan through the
/etc/shibboleth/shibboleth2.xml
configuration file and
remove the REMOTE_USER
directives.
Examine your attributes map file
/etc/shibboleth/attributes-map.xml
and adjust your
requirements if needed. For more information see attributes
documentation
Once you are done, restart your Shibboleth daemon:
$ service shibd restart
$ service apache2 restart
