AttributeEncoderPluginConfiguration

Namespace: urn:mace:shibboleth:2.0:resolver
Schema: http://shibboleth.net/schema/idp/shibboleth-attribute-resolver.xsd

Overview

Attribute encoders convert the internal representation of an IdPAttribute into a particular protocol format. The supported encoders currently support SAML 1, SAML 2, and CAS representations. The mechanism is inherently limited to XML-based output formats.

Attribute encoders are specified with the xsi:type attribute within the <AttributeEncoder> element.

General purpose attribute encoding is best achieved by using the Attribute Registry. Explicit per-attribute encoding continues to be useful when you want to associate an ActivationCondition with the encoder (though this is also possible via rules in the registry).

Note that a source of confusion is that because of the changes to how this code operates, when you add or remove encoders to your resolver configuration, the changes won't take effect until/unless the AttributeRegistryConfiguration is reloaded.

AttributeEncoder Plugin Types

xsi:type	Function
SAML2String	Encodes an IdPAttribute with simple string values as a SAML 2 Attibute.
SAML2ScopedString	Encodes an IdPAttribute with scoped values as a SAML 2 Attibute.
SAML2DateTime	Encodes an IdPAttribute with date/time values as a SAML 2 Attribute.
SAML2XMLObject	Encodes an IdPAttribute with complex XML-based values as a SAML 2 Attribute.
SAML2Base64	Encodes an IdPAttribute with binary values as a SAML 2 Attribute.
SAML1String	Encodes an IdPAttribute with simple string values as a SAML 1 Attibute.
SAML1ScopedString	Encodes an IdPAttribute with scoped values as a SAML 1 Attibute.
SAML1XMLObject	Encodes an IdPAttribute with complex XML-based values as a SAML 1 Attribute.
SAML1Base64	Encodes an IdPAttribute with binary values as a SAML 1 Attribute.

Reference

Common XML Attributes

The following attributes are common to all encoders:

Name	Type	Default	Description
encodeType	boolean	true	Controls whether the output form will contain an encoder-specific indication of the data type of the values. In XML, this takes the form of `xsi:type` attributes, which greatly bloat the size and generally should be avoided for string-valued data. The default is to continue to output the information, but we suggest disabling it in newer deployments and after testing against existing services.
activationConditionRef	Bean Reference		Bean ID of a condition bean that determines whether the encoder should be active, described further here. Mutually exclusive with `relyingParties` attribute and `<ActivationConditionScript>` element
relyingParties	whitespace-delimited list		List of entity IDs for which this Attribute Encoder should be active. Mutually exclusive with `activationConditionRef` attribute and `<ActivationConditionScript>` element

Common XML Elements

The following child element is common to all encoders:

Name	Cardinality	Description
<ActivationConditionScript>	0 or 1	Optional embedded script to supply an activation condition for the encoder. Mutually exclusive with the activationConditionRef and relyingParties XML Attributes.
