Overview

This article provides information that can help you to troubleshoot and resolve Windows authentication login problems.

Check the configuration of the Windows Authentication folder

For login via Windows authentication to work correctly in Dundas Dashboard, its Windows Authentication web folder needs to be properly configured in IIS. In addition, the identity of the application pool under which Dundas Dashboard is running must have permissions to query Active Directory, as this is required when Dundas Dashboard is configured to support Windows authentication.

There are 2 steps when setting up anonymous access or anonymous authentication:

IIS 6.0

1) Enabling anonymous access to the Dundas Dashboard Website or Virtual Directory:

  1. Open IIS Manager
  2. Right click the Dundas Dashboard Website or Virtual Directory, then choose Properties from the context menu
  3. Click the Directory Security tab, then click the Edit button in the Authentication and Access Control section
  4. Check the box beside Enable anonymous access

2) Disabling anonymous access to the Windows Authentication web folder:

  1. Open IIS Manager and expand the Dundas Dashboard Website or Virtual Directory
  2. Right click the Windows Authentication folder, then choose Properties from the context menu
  3. Click the Directory Security tab, then click the Edit button in the Authentication and Access Control section

  1. From IIS Manager, select the Web Sites item. The list of web sites appears on the right.
  2. Locate the Dundas Dashboard website in the list and note its (site) identifier (⪚ from the Identifier column).
  3. Open a command prompt.
  4. Navigate into the folder: C:\Inetpub\AdminScripts
  5. Run the following command (replace SiteIdentifier with the value obtained in step 2):
    cscript adsutil.vbs set w3svc/SiteIdentifier/NTAuthenticationProviders “NTLM”
