Hello Everybody,
I try to configure identity federation between 2 Keystones and I have
some difficulties. I mainly followed this guide
http://docs.openstack.org/developer/keystone/configure_federation.html
<https://exchange-eme3.itn.ftgroup/owa/redir.aspx?REF=T9Q2NhKlOJYyKta69Mjleg2nx0duNoKaJpdWYye5liRiZs0WtEHTCAFodHRwOi8vZG9jcy5vcGVuc3RhY2sub3JnL2RldmVsb3Blci9rZXlzdG9uZS9jb25maWd1cmVfZmVkZXJhdGlvbi5odG1s>
and when I want to test the federated authentication on the Service
Provider (GET
/v3/OS-FEDERATION/identity_providers/master/protocols/saml2/auth), I
have the following response :
Error 500
Unable to locate metadata for identity provider
<http://idp/idp/shibboleth
<https://exchange-eme3.itn.ftgroup/owa/redir.aspx?REF=vo4Mc6JYAdVMJEJHzj2xytyuoUXIFN-Ncj0VpdqxDEtiZs0WtEHTCAFodHRwOi8vaWRwL2lkcC9zaGliYm9sZXRo>>
The only error in keystone.log is:
Unable to locate metadata for identity provider
(http://idp/idp/shibboleth)
I have the following warning in shibd.log:
WARN Shibboleth.SessionInitiator.SAML2 [1]: unable to locate
metadata for provider (http://idp/idp/shibboleth)
Here is the configuration of Shibboleth:
<SPConfig xmlns="urn:mace:shibboleth:2.0:native:sp:config"

What if you try to set IdP FQDN here instead of IP address?
Something like http://idp/idp/Shibboleth.sso/Metadata
Also, make sure that this URI is reachable for your Service Provider
<MetadataProvider type="XML" file="IDP.xml"/>
<AttributeExtractor type="XML" validate="true"
reloadChanges="false" path="attribute-map.xml"/>
<AttributeResolver type="Query" subjectMatch="true"/>
<AttributeFilter type="XML" validate="true"
path="attribute-policy.xml"/>
<CredentialResolver type="File" key="sp-key.pem"
certificate="sp-cert.pem"/>
<ApplicationOverride id="master"
entityID="http://idp/shibboleth";>
<Sessions lifetime="28800" timeout="3600"
checkAddress="false"
relayState="ss:mem" handlerSSL="false">
<SSO entityID="https://idp/idp/shibboleth"; ECP="true">

</SSO>
<Logout>SAML2 Local</Logout>
</Sessions>
<MetadataProvider type="XML"
uri="http://192.168.52.10/Shibboleth.sso/Metadata";
backingFilePath="/var/cache/shibboleth/idp.xml"
reloadInterval="180000" />
</ApplicationOverride>
I m not sure if you need this <ApplicationOverride> object.
</ApplicationDefaults>
<SecurityPolicyProvider type="XML" validate="true"
path="security-policy.xml"/>
<ProtocolProvider type="XML" validate="true"
reloadChanges="false" path="protocols.xml"/>
</SPConfig>
The http://192.168.52.10/Shibboleth.sso/Metadata
<https://exchange-eme3.itn.ftgroup/owa/redir.aspx?REF=jI0ANg_5uqXLZ2PC_HhAlkGcg1eJaTXtg7_2GCWwp8fDx88WtEHTCAFodHRwOi8vMTkyLjE2OC41Mi4xMC9TaGliYm9sZXRoLnNzby9NZXRhZGF0YQ..>
url is working and give me the metadata of the Identity Provider. The
file IDP.xmlwas retrieve from the same URL and put in the directory
/etc/shibboleth.
Both OpenStack servers was installed from DevStack (branch
stable/liberty) on Ubuntutrusty.
Does someone face the same problem?
Cheers.
