Note, this is an advanced configuration feature. Most deployments can rely on the <SSO> shorthand element.

Indicated by type="SAML2", this initiator supports SAML 2.0 authentication requests. As a protocol handler, an entityID must be specified/known, which is then used to check for metadata with an <md:IDPSSODescriptor> role supporting SAML 2.0. The absence of either causes a warning to be logged and the handler otherwise ignores the request.

Attributes

Common Attributes

Specific Attributes

Name	Type	Default	Description

Name	Type	Default	Description
template	local pathname		An HTML template used during transmission of the <samlp:AuthnRequest> message.
outgoingBindings	space delimited list of URLs		List of SAML binding identifiers that determines the order of preferred <md:SingleSignOnService> bindings to use for the request. If this setting is used, failing to list a binding will prevent the use of an IdP that only supports the omitted binding.
acsByIndex	boolean	false	If true, the location of the assertion consumer service to return the assertion to is passed by reference (using an index), rather than passing an explicit URL and binding. Because of the difficulty of ensuring consistent indexing between local configuration and metadata, this is not an advisable feature
postArtifact	boolean	false	If true, the SAML artifact binding is implemented using a form POST rather then a redirect.
isPassive	boolean	false	If true, causes the <samlp:AuthnRequest>'s IsPassive attribute to be "true". Can be overridden by content setting or query string parameter
forceAuthn	boolean	false	If true, causes the <samlp:AuthnRequest>'s ForceAuthn attribute to be "true". Can be overridden by content setting or query string parameter. This asks for forced reauthentication by the IdP (bypassing SSO)
authnContextClassRef	URI		If set, inserts a <samlp:RequestedAuthnContext> element containing the class reference into the <samlp:AuthnRequest>. This can be a whitespace-delimited list of classes to request. Can be overridden by content setting or query string parameter. Tis can also be configured on a per-IdP basis via a RelyingParty setting (only applies if a more general value is not supplied)
authnContextComparison	One of: exact, minimum, maximum, better	exact	If set, inserts a <samlp:RequestedAuthnContext> element containing the comparison operator into the <samlp:AuthnRequest>. Can be overridden by content setting or query string parameter. Ignored unless an authnContextClassRef value is set.
