Client Integrated Authentication using Domain Controller

Client Integrated Authentication using Domain Controller (NTLM) automatically authenticates the client's Windows user name and password. The user does not need to enter a name and password unless their browser cannot authenticate against the domain controller, in which case the user is prompted for an alternative. The password is never transmitted, only an encrypted challenge/response. Authentication is performed using the domain controller. Therefore, the Clearswift Gateway must belong to the domain.

You can choose between two modes for NTLM authentication:

To configure Client Integrated Authentication using Domain Controller:

  1. From the System Center Home page, click Proxy Settings. The Proxy Settings page appears.
  2. Click Authentication Settings to display the Authentication Settings page.
  3. Move the mouse pointer over the User Authentication is Disabled/Enabled section, and click Click here to change these settings.
  4. Select Client Integrated Authentication using Domain Controller, and click Save.
  5. Move the mouse pointer over the NTLM Domain Controller section, and click Click here to change these settings.
  6. Select the Use domain controller radio button.
  7. Enter the fully qualified Domain Name, administrator User Name, and administrator Password of the domain controller whose domain you want the Gateway to join, and click Save.
  8. Click Join domain in the task bar and enter the administrator User Name, and administrator Password of the domain controller whose domain you want the Gateway to join, and click Join.
  9. Move the mouse pointer over the Apache Access Log section, and click Click here to change these settings. To enable or disable the generation of Apache Access logs, select or deselect the Enable Apache access logging check box.
