The com.sun.identity.policy.interfaces package contains SPI for writing custom plug-ins to extend the Policy Service. The classes are used by service developers and policy administrators who need to provide additional policy features as well as support for legacy policies.
Provides methods used to constrain a policy to, for example, time-of-day or IP address. This interface allows the pluggable implementation of the conditions.
Defines an interface for registering policy events when a policy is added, removed or changed. PolicyListener is used by the Policy Service to send notifications and by listeners to review policy change events.
Provides methods used to delegate the policy definition or evaluation of a selected resource (and its sub-resources) to another realm or policy server.
Provides methods to determine the hierarchy of the resource names for a determined service type. For example, these methods can check to see if two resources names are the same or if one is a sub-resource of the other.
Defines an interface to allow pluggable response providers into the OpenSSO Enterprise framework. Response providers are used to provide policy response attributes which typically provide attribute values from the user profile.
Provides methods to determine if an authenticated user is a member of the given subject.
OpenSSO Enterprise includes SPIs that work with the Policy Service framework to create and manage policies. You can develop customized plug-ins for creating custom policy subjects, referrals, conditions, and response providers. For information on creating custom policy plug-ins, see Sample Code for Custom Subjects, Conditions, Referrals, and Response Providers. The following table summarizes the Policy Service SPI, and lists the specialized Policy Service plug-ins that come bundled with OpenSSO Enterprise.
Table 2–1 Policy Service Service Provider Interfaces
Interface |
Description |
---|---|
Subject |
Defines a set of authenticated users for whom the policy applies. The following Subject plug-ins come bundled with OpenSSO Enterprise: Access Manager Identity Subject, Access Manager Roles, Authenticated Users, LDAP Groups, LDAP Roles, LDAP Users, Organization Web, and Services Clients. |
Referral |
Delegates management of policy definitions to another access control realm. |
Condition |
Specifies applicability of policy based on conditions such as IP address, time of day, authentication level. The following Condition plug-ins come bundled with OpenSSO Enterprise: Authentication Level, Authentication Scheme, IP Address, LE Authentication Level, Session, SessionProperty, and Time. |
Resource Name |
Allows a pluggable resource. |
Response Provider |
Gets attributes that are sent along with policy decision to the policy agent, and used by the policy agent to customize the client applications. Custom implementations of this interface are now supported in OpenSSO Enterprise. |
