This is the primary element of an IdP.xml file and is the container for every other element. It must appear once and only once. For most deployments, all the xmlns attributes, which specify the handlers for different aspects of internal IdP operation, should remain unchanged. The mandatory attributes must be changed before the IdP will successfully interoperate with other sites.

defaultRelyingParty: This specifies the relying party to use for a request when no RelyingParty element's name attribute matches the policy URI of an incoming request. Typically, this will be populated with the URI of a federation. This must have a corresponding RelyingParty element or the IdP will fail to start.
providerID: The IdP uses this unique name to identify itself and the assertions it issues. This will usually be assigned by a federation.
AAUrl is provided for backward compatibility with Shibboleth 1.1. It directly specifies the URL used to access the attribute query handler (the AA) for older versions of Shibboleth. Versions 1.2 and higher retrieve this information from metadata.
authHeaderName: If the local user name is passed to the SSO handler using an HTTP header variable other than the default, REMOTE_USER, the name of the variable may be specified here.

defaultAuthMethod: This specifies the authentication method that will be assumed if none is passed through in the SAMLAuthenticationMethod header variable and there is no overriding defaultAuthMethod specified for this particular service provider using a RelyingParty element. If not specified using one of these mechanisms, a default value of urn:oasis:names:tc:SAML:1.0:am:unspecified will be used. Some common authentication methods and corresponding URI's are listed below; for a complete list, please consult section 7.1 of the SAML 1.1 core specifications or your federation's guidelines.

`urn:oasis:names:tc:SAML:1.0:am:password`	The authentication was performed using a password.
`urn:ietf:rfc:1510`	The authentication was performed using Kerberos.
`urn:oasis:names:tc:SAML:1.0:am:X509-PKI`	The authentication was performed using a certificate and key issued to the end user. More specific forms of PKI authentication such as SPKI and XKMS are also assigned URN's in the SAML specs.

maxSigningThreads: This attribute places a limit on the number of threads the IdP will spawn and may be useful for limiting the load of signing and other operations and improving performance. This should be correlated with similar throttles in Apache and Tomcat.
passThruErrors: This boolean attribute determines whether the IdP will relay errors in flows to SP's for use in displaying these errors to the browser in the case of an unsuccessful transaction.
resolverConfig specifies the location of the configuration file for the resolver the IdP uses to build attributes and if unspecified defaults to /conf/resolver.xml. Detailed information is available on configuring resolver.xml itself.

Protocol Handlers

The Shibboleth Identity Provider's capability to handle requests is divided into a set of protocol handlers that respond to different types of external calls to support the Shibboleth architecture and requests from other SAML-based applications. There are four main protocol handlers bundled with Shibboleth 1.3, each of which must be called out in a ProtocolHandler element to be functional. Each of these elements in turn contains one or more Location element specifying the URL's which that particular protocol handler will respond on. Some of these locations specified must match those protected by Apache and passed through mod_jk in order to function properly in some deployment setups.

A separate handler has been written to handle SSO requsts for eAuth compliance.

<ProtocolHandler implementation="classname">

Example:

<ProtocolHandler implementation="edu.internet2.middleware.shibboleth.idp.provider.ShibbolethV1SSOHandler">
	<Location>https?://[^:/]+(:(443|80))?/$IDP_WEBAPP_NAME$/SSO</Location>
</ProtocolHandler>

This element defines an individual protocol handler referenced by the classname of the Java class implementing it. Additional attributes may be specified for particular protocol handlers as part of this element. The following protocol handlers are bundled with Shibboleth v1.3:

edu.internet2.middleware.shibboleth.idp.provider.SAMLv1_AttributeQueryHandler : Requests for attribute release based on handles or other principal identification are handled by the attribute query handler. The contained <Location> element must be protected by https:// and Apache in order to properly authenticate requesting entities.
edu.internet2.middleware.shibboleth.idp.provider.SAMLv1_1ArtifactQueryHandler : Artifacts are created, stored, and passed by the artifact query handler. The contained <Location> element defines the base URL at which artifacts will be stored and must be protected by https:// for a variety of security and confidentiality reasons.
edu.internet2.middleware.shibboleth.idp.provider.ShibbolethV1SSOHandler : The SSO handler is responsible for generating authentication assertions and handles in response to authentication requests. The contained <Location> should always be protected by https:// and Apache in order to protect login information from various attacks. The credentials used to do this may differ from those used to handle interactions with other Shibboleth components due to the browser interaction required.
edu.internet2.middleware.shibboleth.idp.provider.E_AuthSSOHandler : This special protocol handler allows for backward compatibility with SAML 1.0, is eAuth compliant, and interoperates successfully with all other eAuth compliant products.

<Location>URL</Location>

This element specifies a URL on which the encapsulating <ProtocolHandler> will listen.
