Business Objects XI doesn’t come with a standard tool that let administrators to remove user session. But this is doable using their SDK. (Download here  BO XI kill session tool).  Note: I only tested in XI R3

Unzip and put the folder KillSession into the webapps folder under tomcat.

Before you can use it, copy the all library files from CmcAppActions (C:\Program Files\Business Objects\Tomcat55\webapps\CmcAppActions\WEB-INF\lib) to the C:\Program Files\Business Objects\Tomcat55\webapps\KillSession\WEB-INF\lib

You might need to restart Tomcat (or not ? ).
