Check the authentication settings

1. Open web.config in C:\Program Files\Snow Software\Snow License Manager\Web and verify that Windows authentication is set to true.
2. Set the UseWindowsAuthentication key to true.
3. In IIS Manager, select the Snow License Manager site and click Authentication. Verify that Windows Authentication is enabled and Anonymous Authentication is disabled.
4. Check the following entries in Feature Delegation:
   • Authentication - Anonymous
   • Authentication - Basic
   • Authentication - Windows
5. If you changed any of these settings, run iisreset.
6. Verify that the user is configured correctly in Snow Management and Configuration Center (SMACC).
7. Verify that the username uses the format ADDomain\Useraccount.
8. In SMACC, verify that Password never expires is selected.

Update the API authentication configuration

In web.config, add the following block immediately before the closing </configuration> tag:

<location path="api">
  <system.webServer>
    <security>
      <authentication>
        <anonymousAuthentication enabled="true" />
        <basicAuthentication enabled="false" />
        <windowsAuthentication enabled="false" />
      </authentication>
    </security>
  </system.webServer>
</location>

Save web.config, then restart IIS.
