Hi there,
I'm trying to config the latest version of DNN with the latest version of the Active Directory Module
here is what I'm getting in a red box

Accessing Global Catalog:
OK
Checking Root Domain:
FAIL
Accessing LDAP:
OK
Find all domains in network:
3 Domain(s):
Domain1
SubDomain1.Domain1
SubDomain2.Domain1


I'm using the following settings:
Enabled? Checked
Hide Login Controls? Unchecked
Synchronize Role? Unchecked
Do Not Automatically Create Users? Unchecked
Provider : ADSIAuthenticationProvider
Authentication Type: Secure
Root Domain: Domain1
Email Domain: left Empty
Default Domain: Domain1
Auto-login IP Address (Optional): left Empty

i already raised the trust to FULL and UN-commented the impersonation=true tag in the web.config

Thanks in advance

You can find the documentation on the CodePlex site (here) that explains what you need to do to use impersonation.
