Correlation of TCP/IP connections to processes

To simplify UNIX maintenance in a high turnover user environment, we have all security done at the workstation/Novell side. If their User Id is valid for the application they are asking to use, we let it go through as a common user name. Power Builder / INet TSR is the front end. Unfortunately, with Informix I-star and Solaris, there does not seem to be any correlation so we can track back to the originator of a process. The netstat -a shows all the active connections, which we can track back to a workstation, but we can't correllate that to a process. Is there anyway to reconnect this information so we can call a user to find out what request they made when we see a problem? All users have the same name on the Solaris side. Thanks, Ray
