The SAML2ScopedString attribute encoder encodes an IdPAttribute with "scoped" string values as a SAML 2 Attribute. This encoder typically combines the value and scope strings, adds a delimiter, and produces a simple string-valued element.

Schema Name and Location

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

Prior to V3.3 supplied plugins were defined by a schema type (xsi:type) in the urn:mace:shibboleth:2.0:encoder schema , which is located at http://shibboleth.net/schema/idp/shibboleth-attribute-encoder.xsd.  This is still supported, but every element or type in the  urn:mace:shibboleth:2.0:encoder schema has an identically named version in the urn:mace:shibboleth:2.0:resolver  schema.

Attributes

Common Attributes

NameTypeDefaultDescription

encodeType

booleantrueControls 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. For compatibility with V2, the default is to continue to output the information, but we suggest disabling it in newer deployments and after testing against existing services.

Bean Reference

Bean ID of a condition bean that determines whether the encoder should be active, described further here.

Specific Attributes

NameTypeReq?DefaultDescription
name
StringY
Value to put into the "Name" attribute of the output <AttributeValue> elements
nameFormat
String
urn:oasis:names:tc:SAML:2.0:attrname-format:uri
Value to put into the "NameFormat" attribute of the output <AttributeValue> elements
friendlyName
String

Value to put into the "FriendlyName" attribute of the output <AttributeValue> elements
scopeAttribute
String
ScopeIf scopeType is "attribute", then the scope is passed an XML attribute inside the <AttributeValue> elements with this name while the (unscoped) value is passed in the content of the element
scopeDelimiter
String
@If scopeType is "inline", then the output <AttributeValue> element content is constructed by concatenating the unscoped value, the value of this attribute, and the scope
scopeType
"attribute" or "inline"
inlineDefines what format the attribute is to be encoded in, generally should be left alone
