Hi guys,

First of all, I want to congratulates you for your solution, It's really easy to use !

But unfortunately I have a problem with the Windows authentication.

I set the ASP authentication with the Add-in "Asp.net" on the admin page and I enable " Windows authentication and ASP impersonation" on IIS.

This configuration works well when Users complete a Survey. (I can see they're windows credentials on each report) 

But when I try to go back to the Admin Page of Survey project, "https://10.x.x.x/Survey20/" and complete the login form, it ask for my windows credentials. 

I do it but it redirect me on this page "https://10.x.x.x/Survey20/NSurveyAdmin/accessDenied.aspx?surveyid=1&menuindex=-1" and this message appear "Unauthorized. Access is denied due to invalid credentials.".

I try a lot of things but nothing works... So if someone have a solution or an idea, please tell me :)

Thanks in advance.
