I have enabled pass through authentication and managed to important all of my users and accounts...

 

But no matter what i try to do Pass through authentication will not work...

 

When i press save it just says "SUCCESS :Active Directory authentication is enabled."

 

When i go to a computer and go to the URL i get a popup box asking for login credentials like the windows login box asking for a username and password, if i cancel it, i go to the helpdesk and it asks for a username and password...

 

I have attached an image which shows the options we have put in....

 

Thanks in advance!
