MappedAttributeDefinition

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

Overview

The Mapped AttributeDefinition performs a many-to-one mapping from source attributes values to a return value according to a series of mapping statements. If an input value matches no mapping rule, then a default can be provided.

Description

<DefaultValue>

0 or 1

Describes the action to be taken if any input value does not match one of the <ValueMap>'s <SourceValue> elements that follow. If the passThru attribute is set to "true", then the input value is passed through untouched, otherwise the contents of the element are used as the default value.

<ValueMap>

1 or more

The <ValueMap> element supports two child elements: <ReturnValue> and <SourceValue>, see below

The <ValueMap> element’s content consists of:

XML Element Name

Cardinality

Description

<ReturnValue>

1

The content is used as the output value if any of the source values match. Replacement rules from Matcher.replaceAll(String) apply.

<SourceValue>

1 or more

The content is matched against each input value and if it matches, then the mapped <ReturnValue> is output. The mapping process depends on the value of the partialMatch attribute, which defaults to false.

If partialMatch is set to true, then the source value is checked for containment within the input value, and if so, the return value replaces the original.

If partialMatch is set to false, then the source value is a Java Regular Expression applied to the input value, and if a match, then the return value is applied as a replacement, with all matches replaced by the return value.

Setting the caseSensitive attribute (default true) to false allows case insensitive comparisons to be made. This is only valid for regular expression matching (i.e., when partialMatch is false).

At least one dependency element is required.
