Windchill Program Changes
Form-based authentication cannot be transparently handled at the protocol level and some clients used to access Windchill must be specifically designed to support form-based authentication. For example, Windchill programs, such as visualization services or Windchill Desktop Integration, may require changes when form-based authentication is used. To import parts through the Windchill Gateway for Cadence Allegro Design Workbench, the URL for the SimpleTaskDispatcher servlet that is used must include the /protocolAuth URL prefix.
For information about making visualization changes for form-based authentication, see WVS Considerations with Form-based Authentication.
For information about making Windchill Desktop Integration changes, see Desktop Integration under Advanced Customization.
