If your form-based authentication solution uses J2EE compliant authentication mechanism, user name will be passed automatically to Servigistics InService and below steps should be skipped.

Create and register a servlet filter that extends wt.httpgw.filter.AbstractRemoteUserFilter. In this filter, implement getRemoteUser method. The method, getRemoteUser should return user ID sent from your single sign on solution. Be aware that if your code passes the user ID through a request header, you must ensure that the code does not accept this particular header from clients.
