Configuring an Agent for SSL offloading
You can configure a Web Agent for SSL offloading using either the AM admin UI or ssoadm:
- AM admin UI: navigate to: Realms > [Realm Name] > Applications > Agents > Web > [Agent ID] > Advanced and enable Override Request URL Protocol.
- ssoadm: enter the following command: $ ./ssoadm update-agent -e [realmname] -b [agentname] -u [adminID] -f [passwordfile] -a com.sun.identity.agents.config.override.protocol=truereplacing [realmname], [agentname], [adminID] and [passwordfile] with appropriate values.
When this enabled, the protocol part of the incoming request is overridden with the one specified in the com.sun.identity.agents.config.agenturi.prefix property, so you also need to ensure this is set appropriately.
Note
You should enable this property if the agent sits behind a SSL/TLS offloader, a load balancer or a proxy, and the protocol used by users is different to the protocol used by the agent.
You can set this property using either the AM admin UI or ssoadm:
- AM admin UI: navigate to: Realms > [Realm Name] > Applications > Agents > Web > [Agent Name] > Global > Profile > Agent Deployment URI Prefix and specify the correct URI.
- ssoadm: enter the following command: $ ./ssoadm update-agent -e [realmname] -b [agentname] -u [adminID] -f [passwordfile] -a com.sun.identity.agents.config.agenturi.prefix=[URI]replacing [realmname], [agentname], [adminID], [passwordfile] and [URI] with appropriate values.
Example
For example, with the following settings:
Load balancer URL=http://lb.example.com:8080 com.sun.identity.agents.config.override.protocol=true com.sun.identity.agents.config.agenturi.prefix=https://agent.example.com:443/amagentWhen a request is received, the agent overrides the protocol part of the incoming URL (http) with the protocol specified in com.sun.identity.agents.config.agenturi.prefix (https) and uses this for the goto parameter.
