Accessing Attributes from LoginHandler via attribute-resolver.xml

[Paul Hethmon]

I do this and had to create a custom principal to hold the info. The login handler pushes the data into it during authentication. Then I have a separate data resolver that pulls the info out as attributes during that phase. So the principal is my data transport between the two distinct plug ins.

Hi all-
So, I’ve been googling and searching the mailing list for a bit with minimal look, and figured it was about time for me to give up and ask for help.

Anyway, we’re developing a custom login handler for a project, and it will pretty much be the only way for us to get attributes about the user (the data store we are using isn’t something we can access over LDAP or SQL). The login handler plugin should be able to return them in the requestContext, which I know I could probably use somewhere in the DataConnector pieces, but I need to use it in the AttributeDefinition piece instead. For example, let’s say parallel to principalName it returns another value “fullName”. I’d like to do something like the following, but it doesn’t work:

    <resolver:AttributeDefinition xsi:type="Script" xmlns="urn:mace:shibboleth:2.0:resolver:ad" id="EtanFullName" >
     <Script><![CDATA[
      importPackage(Packages.edu.internet2.middleware.shibboleth.common.attribute.provider);
      EtanFullName = new BasicAttribute("EtanFullName");
      EtanFullName.getValues().add($requestContext.fullName);
     ]]></Script>
    </resolver:AttributeDefinition>

I get the following error (trimmed up a bit for here) in the idp-process.log:

12:37:24.988 - ERROR [edu.internet2.middleware.shibboleth.common.attribute.resolver.provider.attributeDefinition.ScriptedAttributeDefinition:135] - ScriptletAttributeDefinition EtanFullName unable to execute script
com.sun.phobos.script.util.ExtendedScriptException: org.mozilla.javascript.EcmaError: ReferenceError: "$requestContext" is not defined. (<Unknown Source>#3) in <Unknown Source> at line number 3

Any ideas?

Thanks in advance.
