Summary
When accessing the Laserfiche Directory Server Security Token Service configuration page, you may get a 404 error page and receive the following error message: "The resource cannot be found."
Cause
One potential cause for this situation is that you may have inadvertently turned on both Forms authentication and Windows authentication. Internet Information Services does not allow both authentication options to be used simultaneously.
Resolution
Disable Forms authentication for the LFDSSTS IIS application.
