Hi folks - I realize this has been asked once or twice and forgive me I haven't looked at Shibboleth config recently... I'm looking to add a specific attribute that is resolved for each user in the audit log. I see the skeletal example in the wiki, but I just don't understand what I am to use as a value. It mentions the value should be a "Function<ProfileRequestContext,Object> instance" - but quite honestly I don't know exactly what that means. Specifically I'd like to put the uid attribute in the audit log (which is different than the %u already present.) Thanks for any guidance.
