I have done this as a test, with opensso as the idp.
There was nothing special with the metadata file.

But in the SP attribute-map.xml file I uncommented the section:
  <!--Examples of LDAP-based attributes, uncomment to use these... -->

  and added:
     <Attribute name="urn:mace:dir:attribute-def:uid" id="uid"/>
     <Attribute name="urn:oid:0.9.2342.19200300.100.1.1" id="uid"/>

In the shibboleth2.xml file, since OpenSSO does not return a eppn,
but only a uid (unscoped)  I change the REMOTE_USER=

REMOTE_USER="eppn uid persistent-id targeted-id"

So in our case, opensso sends LDAP attrubutes including
givenName, sn, cn and uid.
