To get an auto AD login as a Client or Staff user via the HelpMaster Pro Web Module, an Internet Explorer security zone needs to be modified to allow the current AD user login to be passed through to the Web Module as follows;

1. Open IE's Internet options from the 'Tools' menu and click on the 'Security' tab,
2. Click on the 'Custom level...' button and scroll to the bottom of the 'Settings' list,
3. Under 'User Authentication'>'Logon', select the 'Automatic logon with current user name and password' option.

Save the above change, close IE and then browse to the http://[ServerName]/[VirtualDirectory]/Winlogin.aspx page, or any other secure page of the Virtual Directory to effect an AD login. Set up a Favourite or Bookmark to the previous page for future AD logins.

In order to address the same issue in Firefox, you'll need to perform the following steps (otherwise you may get a message box : "Authentication Required in FireFox"):

1. Open Firefox
2. Navigate to the url about:config
3. In the filter bar, type ntlm. You'll see the following 2 items:
network.automatic-ntlm-auth.allow-proxies
network.automatic-ntlm-auth.trusted-uris
4. Make sure that the allow-proxies boolean value is true (this is the default)
Then double click the entry for trusted-uris and enter your comma separated domain/s ( eg. "localhost,prdsoftware.com")
