Hi,

I'm stuck with this message each time I try to update DNN when configuring the AD parameters.

How can I get rid of that ?

Thanks

Impersonation solved my problem.

Thanks for your support and your fast answer !

 What credentials does the impersonated user need for usuing Active Directory.  I'm receiving the same error, and I have the user set as an adminitrator on the server.  THIS IS DRIVING ME NUTS!  There is no clear documentation anywhere, just "add impersonation to the web.config".

PLEASE HELP ME!
