Accessing the logout feature

[Stapleton, Steven J. (James)]

I'm trying to setup my SP to provide a sign out option, using this:
https://wiki.shibboleth.net/confluence/display/SHIB2/NativeSPLogoutInitiator

Setup:
Installation:
Apache: 2.2.3
Shibboleth: 2.4.3
OS: RHEL 5

I am getting a configuration error - I'm guessing I put something in incorrectly. Does anyone have some sample code I could follow, or advice on what I've done wrong?

My default configuration had the following under the "SPConfig"-=>"ApplicationDefaults"->"Sessions" space in my shibboleth2.xml
==========START ORIGINAL==========
            <Logout type="SAML2">SAML2 Local</Logout>
==========END ORIGINAL==========

==========START NEW==========
            <Logout type="SAML2">SAML2 Global</Logout>
            <LogoutInitiator>
              <Location>/Shibboleth.logout</Location>
            </LogoutInitiator>
==========END NEW==========

Thanks,
-Jim Stapleton
