usage "AttributeRequesterString" in attribute-resolver.xml

[Björn Urbanek]

Hello!

I want to use the "AttributeRequesterString" Variable for publish an
attribute based on this string to create a own SAML attribute with the
following syntax:

username at requester

Currently I have only found a usage case of the "AttributeRequesterString"
in the attribute-filter.xml.


A part of the attribute-resolver.xml :

<!-- The username is my sAMAaccountname of  my LDAP directory. -->

<resolver:AttributeDefinition
    id="eduPersonPrincipalName"
    xsi:type="Simple"
    xmlns="urn:mace:shibboleth:2.0:resolver:ad"
    sourceAttributeID="sAMAccountName">
        <resolver:Dependency ref="myLDAP" />

        <resolver:AttributeEncoder
    xsi:type="SAML1String"
    xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
    name="urn:mace:dir:attribute-def:eduPersonPrincipalName" />

        <resolver:AttributeEncoder
    xsi:type="SAML2String"
    xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
    name="urn:oid:1.3.6.1.4.1.5923.1.1.1.6"
    friendlyName="eduPersonPrincipalName" />
</resolver:AttributeDefinition>


<!-- Try to get the RequesterString -->

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

     <resolver:AttributeEncoder xsi:type="SAML2String"
xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
                                name="AttributeRequesterString" />
</resolver:AttributeDefinition>


A part of the attribute-filter.xml:

<!-- try to publish the requester for testing -->

  <afp:AttributeFilterPolicy id="SPrequester">
    <afp:PolicyRequirementRule xsi:type="basic:ANY" />
    <afp:AttributeRule attributeID="SPrequester">
        <afp:PermitValueRule xsi:type="basic:ANY"/>
    </afp:AttributeRule>
  </afp:AttributeFilterPolicy>



Currently no value will be published. 
(How) Can I use the requester attribute or a similar value to create a new
attribute for publishing to the SP?

Many thanks so far!


Best regards
