Sun Java System Access Manager Policy Agent 2.2 Guide for Apache HTTP Server 2.0.54

Validating Client IP Addresses

This feature can be used to enhance security by preventing the stealing or hijacking of SSO tokens.

The web agent configuration file contains a property titled, which by default, is set to false.

If you set this property value to true, client IP address validation will be enabled for each incoming request that contains an SSO token. If the IP address from which the request was generated does not match the IP address issued for the SSO token, the request will be denied. This is essentially the same as enforcing a deny policy.

This feature should not be used, however, if the client browser uses a web proxy or if there is a load balancer somewhere between the client browser and the agent-protected deployment container. In such cases, the IP address appearing in the request will not reflect the real IP address on which the client browser runs.
