Groovy as scripting language in Shibboleth-IdPv3

The default language to write ScriptedAttributeDefinition is EcmaScript, but it's easy to switch to groovy.

First of all download latest groovy, unzip it, locate the groovy-x.x.x.jar and groovy-jsr223-x.x.x.jar and copy the in the webapp/WEB-INF/lib/ dir of the unpacked shibboleth-idp source. Install again shibboleth-idp.

As proof of concept, just rewrite the "email" attribute definition which is, in the distribution attribute-resolver.xml, a template attribute.

Modify attribute-resolver.xml to include:

The included script file is:

Copy it in the $IDP_HOME/script/ directory

In order to test it, just add: <logger name="org.example.idp.scripted.groovy" level="DEBUG"/> to logback.xml, be sure to reload both attribute-resolver (./bin/reload-service.sh -id shibboleth.AttributeResolverService) and logger (./bin/reload-service.sh -id shibboleth.LoggingService), and run a aacli call.

DEBUG [org.example.idp.scripted.groovy.email:13] - value: [a_user@example.org]

A pure ruby Attribute Authority client

Even if you can query IdP Attribute Authority with resolvertest, and you can test the tiny details with a curl call, a ruby attribute authority client is handy should you desire, for instance, to bulk load the IdP with many parallel requests.

Moreover, the curl approach is very slow because you need to modify the request xml file to put a timely IssueInstant and a unique RequestID.
