I will configure LanSweeper that only users in AD_Group_X can access the webinterface.
But when I follow the steps in your tutorials It won't work.
I have changed the following steps:
- modified the Ultidev authentication to [Windows integrated] (Kerebos / NTLM)
- I have edited the webaccess rules to DOMAIN\USERGROUP

I use LS version: Beta v. 5037

I get the following error message while visiting the webinterface. (it seems to be a timeout.)
Webserver Error
