2.5, AttributeExtractor, from Metadata

[Steven Carmody]

I added this element to my shibboleth2.xml config file:

<AttributeExtractor type="Metadata" errorURL="errorURL" 
DisplayName="displayName"/>

the log files indicate that, at startup, Shib is recognizing this 
element ....

but when I hit my target site, I don't see anything in the log files 
related to processing this...

all my SP does is dump out the received info -- it prints out the 
attributes seent by my IDP, but I don't see either of the elements I was 
expecting from the IDP's metadata ....

maybe I just mis-understand this new feature -- I thought these values 
would be provided to my app in the usual way ? Or are they only 
available via the templates used by the AttributeChecker ?
