HeaderVariableLoginModule

Hi

I have a SAP WAS 6.40 Java environment, and I'm attempting to follow the instructions in the SAP Library (Adjusting the Login Module Stacks for Using Header Variables) to use the HeaderVariableLogin Module. I have to add the login module, as it does not already exist, the SAP Library gives these details for adding the login module:

Class Name: <b>com.sap.security.core.server.jaas.HeaderVariableLoginModule

</b>

However, doing a search for this Class reveals that it exists in only one place on my system, and that is in the <b>com.sap.security.core.jar</b> file at this path:

<b>com.sap.security.core.logon.imp.HeaderVariableLoginModule</b>

When I try either of these paths, I get a message in the security log file stating "cannot load a login module".

Any help would be appreciated.
