We enabled passthrough authentication some time ago and it was working fine. At some point it stopped functioning correctly, it may have occured during one of the many patches and updates, but we aren't sure. I have revisited the instructions on how to set this up, but I ran into an odd situation. When I went into IIS to set verify and set the permissions, what i found was confusing and a possible problem. Within the Authentication screen of the "SolarWinds NetPerfMon" site I found the following:
Name Status Response Type
Anonymous Authentication Enabled
ASP .NET Impersonation Disabled
Basic Authentication Disabled HTTP 401 Challenge
Forms Authentication Enabled HTTP 302 Login/Redirect
Windows Authentication Enabled HTTP 401 Challenge
Alerts: "Challenge-based and login redirect-based authentication cannot be used simultaneously."
Now what should these settings be set to, to allow for Passthrough Authentication?
