Install shibboleth DiscoveryService1.1.1

Instructions are ok, but I tripped on some pitfalls.

1) when deploying service, service name has to be
discovery
, so the URL in tomcat should be /discovery and deployment fragment in /etc/tomcat5.5/Catalina/localhost should look like:

<Context docBase="/opt/shibboleth-ds/war/discovery.war"
privileged="true"
antiResourceLocking="false"
antiJARLocking="false"
unpackWAR="false"
swallowOutput="true" />

this should be obvious from war name, but not to me.
2) before doing install.sh I had to remove servlet-api-2.3.jar from directory /lib. Otherwise I had an error in tomcat:
INFO:
validateJarFile(/var/lib/tomcat5.5/webapps/discovery/WEB-INF/lib/servlet-api-2.3.jar)
- jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class:
javax/servlet/Servlet.class
3) no log starts, unless you hit the url of the discoveryService, which is https://my-server.com/discovery/WAYF
4) session initiator of shibboleth-sp should look like:

<SessionInitiator acsByIndex="false" type="Chaining"
Location="/discovery" id="discovery" relayState="cookie">
<SessionInitiator type="SAML2" defaultACSIndex="1"
template="bindingTemplate.html"/>
<SessionInitiator type="Shib1" defaultACSIndex="5"/>
<SessionInitiator type="SAMLDS"
URL="https://my-server.com/discovery/WAYF"/>
</SessionInitiator>

With the SP packeged with debian/lenny, i had to add
acsByIndex="false" in the first line.
5) with the same shibboleth-sp I had to regenerate metadata from Shibboleth.sso/Metadata, as it was missing:

<md:Extensions>
<DiscoveryResponse
xmlns="urn:oasis:names:tc:SAML:profiles:SSO:idp-discovery-protocol"
Location="http://bacedifo.cesia.unimo.it/Shibboleth.sso/discovery"
index="1"/>
</md:Extensions>

before the keys section (<md:KeyDescriptor use="signing">), inside md:SPSSODescriptor section.
