## 6.2. Kinds of Agent Profiles

When you open the OpenAM console to configure agents for the top level realm, you can choose from a number of different types of agents. Web and J2EE policy agents are the most common, requiring the least integration effort.

Web

  You install web agents in web servers to protect web sites.

J2EE

  You install J2EE agents in web application containers to protect web applications.

Web Service Provider

  WSP agents are for use with Web Services Security.

Web Service Client

  WSC agents are for use with Web Services Security.

Discovery

  The Discovery Service agent has the trust authority configuration that OpenAM uses to communicate with a Liberty Discovery Service.

STS Client

  The Security Token Service client agent is for securing requests to the Security Token Service.

2.2 Agents

  Version 2.2 web and J2EE policy agents hold their configuration locally, connecting to OpenAM with a user name, password combination. This kind of agent is provided for backwards compatibility.

OAuth 2.0 Client Agent

  OAuth 2.0 clients are registered using this type of policy agent profile.

Agent Authenticator

  The agent authenticator can read agent profiles by connecting to OpenAM with a user name, password combination, but unlike the agent profile administrator, cannot change agent configuration.
