Summary

Some applications do not support NTLM authentication.

Problem

The following is a list of applications which are known not to support authenticated proxies (NTLM Identification / NTLM Authentication / Proxy Authentication):

Solution

If the application listed above doesn't have its own article, use the steps below:

  1. Create a custom category for the appropriate domains — see https://help.smoothwall.net/Latest/Content/modules/guardian3/cgi-bin/guardian/customcategory.htm
  2. Avoid using the Guardian category that the domain in question belongs to, as this may contains domains for other applications.

  3. Add the following to authentication exceptions:
    • The new custom category created in step 1
    • SSL /CRL category
    • Software Updates category

    See https://help.smoothwall.net/Latest/Content/modules/guardian3/cgi-bin/guardian/authexceptions.htm

  4. Create an Allow web filter policy for custom category created in step 1 — see https://help.smoothwall.net/Latest/Content/modules/guardian3/cgi-bin/guardian/filteringpolicywiz.htm
  5. Move the new policy to be above any block policies in the Web filter policies table — see https://help.smoothwall.net/Latest/Content/modules/guardian3/cgi-bin/guardian/policies.htm
  6. If you continue to experience issues, filter the Web filter logs by the IP of a test client, attempt to open the site / application, and add the domains that appear in the web filter logs to the authentication exceptions.
