Authorization Server is a client side replica of Policy Server. It needs to be installed with Access Manager Java Runtime environment. It caches policy server data and synchronizes it on a regular basis. Even though Policy Server goes down, Authorization server still serves your requests.
However there is a limitation on the data that authorization server can provide. Authorization server API provides ways of accessing basic attributes of user, group and ACL. PDPrincipal object is one such example API. For using Authorization API, developers have to first create
PDAuthorizationContext and supply that as input to any authorization API. If you want to create user or group, you need to go through Policy Server API.
With TAM 6.0, Authorization and Policy Server API are clubbed into one and are called Access Manager Application Development Kit(AMADK). com.tivoli.pd.jazn API are specific to Authorization server in AMADK.
