About
This page describes the concept of Authentication Materials used in the Context Data Model 1.1. Authentication Materials are needed to open a Context.
Authentication Materials are classes which implement the IdAS IAuthNMaterials interface. This is only a marker interface without methods.
Authentication Material Types
The interface IAuthNMaterials defines the following string identifiers for common types of Authentication Materials:
public static final String AUTHNMATERIALS_TYPE_ANONYMOUS = "urn:udi:authnmaterials:1.0:anonymous"; public static final String AUTHNMATERIALS_TYPE_LEASTPRIVILEGED = "urn:udi:authnmaterials:1.0:leastPrivileged"; public static final String AUTHNMATERIALS_TYPE_IMPLIED = "urn:udi:authnmaterials:1.0:implied"; public static final String AUTHNMATERIALS_TYPE_USERNAMEPASSWORD = "urn:udi:authnmaterials:1.0:usernamePassword"; public static final String AUTHNMATERIALS_TYPE_PINFOCARD = "urn:udi:authnmaterials:1.0:p-infocard"; public static final String AUTHNMATERIALS_TYPE_MINFOCARD = "urn:udi:authnmaterials:1.0:m-infocard"; public static final String AUTHNMATERIALS_TYPE_SAMLPOLICY = "urn:udi:authnmaterials:1.0:samlpolicy";
- This is needed in scenarios when you do not know a priori what type(s) of Authentication Materials a Context accepts.
- For example, for R-Cards we use UDIs to point to Higgins Contexts and Entities. When a UDI is resolved, we need to know what type of Authentication Materials is needed for opening the Context it points to.
- The above identifiers can have a query string for passing additional information (e.g. constraints on the accepted Authentication Materials)
- In the case of urn:higgins:authmethod:1.0:m-infocard this additional information could be a base64 encoded I-Card <object> element.
urn:higgins:authmethod:1.0:m-infocard?policyhere
- The special identifier urn:higgins:authmethod:1.0:implied means that the party trying to open the Context must somehow know by itself what Authentication Materials to use. E.g. in SSO scenarios, that party may already have a session established with the user, or in some other way know their credentials.
