By adding this generic property to LotusConnections-config.xml, all requests will contain a header X-Lconn-Userid , that contains the logged in user.

Depending on your configuration, this most likely is the email address of the logged in user.

<!-- To display email of logged in user in IHS: -->  
<genericProperty name="">true</genericProperty>  

You can then add this header value to the log configuration in apache/ihs, so you have logs including the user . This is pretty helpful for tracing problems ….

Please note that this is not officially supported in any way !
