Refers to how the AuthModule will be installed on the site. If true, the module is installed locally to the web application in the bin folder and the modules are loaded one by one in the web.config. False would indicate the module is installed into the GAC and the modules are loaded globally into the server. The consequence of a true is that web.config files published to the site will automatically have the modules entries added and a false one would not. The default is false.
