The Prescoped attribute definition turns a simple string-valued attribute into a two-part scoped attribute by splitting the input attribute into three parts, the value, a (fixed) delimiter, and the scope/suffix. Such attributes can be used as input to the SAML2ScopedStringEncoder and SAML1ScopedStringAttributeEncoder  attribute encoders.

The prescoped attribute definition is useful when a data connector returns attributes with values which already have an appropriate scope appended in the source system.

Schema Name and Location

This xsi:type is defined in the urn:mace:shibboleth:2.0:resolver namespace 3.3, the schema for which can be located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver.xsd

Prior to V3.3 supplied plugins were defined by a schema type in the urn:mace:shibboleth:2.0:resolver:ad namespace, the schema for which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-resolver-ad.xsd. This is still supported, but every element or type in the old namespace has an equivalently named (but not necessarily identical) version in the urn:mace:shibboleth:2.0:resolver namespace. The use of the urn:mace:shibboleth:2.0:resolver namespace also allows a relaxation of the ordering requirements of child elements to reduce strictness.

Attributes

Any of the common attributes can be specified. In addition, the optional scopeDelimiter attribute defines the delimiter which separates the value from the scope. The default is "@".

Child Elements

Any of the common child elements can be specified.

Example

<AttributeDefinition xsi:type="Prescoped" id="eduPersonPrincipalName">
    <InputDataConnector ref="myLDAP" attributeNames="eduPersonPrincipalName" />
    <AttributeEncoder xsi:type="SAML1ScopedString" name="urn:mace:dir:attribute-def:eduPersonPrincipalName" encodeType="false" />
    <AttributeEncoder xsi:type="SAML2ScopedString" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.6" friendlyName="eduPersonPrincipalName" encodeType="false" />
