SAML 1 Base64 Attribute Encoder

The SAML 1 Base64 attribute encoder creates SAML 1 <Attribute> elements from resolved attributes with an <AttributeValue> element for each value. The content of the <AttributeValue> element is a Base64 encoded byte array. This encoder is only used for SAML 1 messages and will be ignored when the IdP is answering other protocol messages.

Please Note

The LDAP data connector will Base 64 encode values of attributes that are marked as binary (see Other Connection Properties) so you should use a normal string attribute encoder for such attributes.
This encoder only operates on attributes whose values are byte arrays. It will not attempt convert values of other types into a byte array.

Define the Encoder

Attribute encoders are defined in a <resolver:AttributeDefinition> after all <resolver:Dependency>.

To define a new SAML 1 Base64 attribute encoder, create a <resolver:AttributeEncoder xsi:type="SAML1Base64" xmlns="urn:mace:shibboleth:2.0:attribute:encoder"> with the following required attribute:

name: Becomes the AttributeName attribute on the created SAML 1 <Attribute> element.

and the following optional attribute:

namespace: Becomes the AttributeNamespace attribute on the created SAML 1 <Attribute> element. Defaults to urn:mace:shibboleth:1.0:attributeNamespace:uri.

SAML 1 Base64 Attribute Encoder within a Simple Attribute Definition

<resolver:AttributeDefinition id="UNIQUE_ID" xsi:type="ad:Simple">

     <resolver:Dependency ref="DEFINITION_ID_1" />
     <resolver:Dependency ref="CONNECTOR_ID_2" />

     <resolver:AttributeEncoder xsi:type="SAML1Base64" xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
                                name="ATTRIBUTE_NAME_1" />

</resolver:AttributeDefinition>

Defining more than one attribute encoder allows a deployer to transform a single attribute into multiple <Attribute> with different names and/or namespaces.
