401 Authorization Required

Even if the user is providing the correct authentication details, a misconfiguration of the IIS server (on which Sharepoint runs) may cause the aforementioned error.

Here follows 2 default Sharepoint/IIS configurations that you may try to apply to solve the problem:

  1. Sharepoint 2007 with IIS 7.0
    • Go to the IIS settings , choose the Sharepoint site you need to configure, and double click on the "Authentication" icon

    • Enable the "Windows Authentication"
    • Click on "Advanced settings" and ensure "Enable Kernel-mode Authentication" option is ticked.

  2. Sharepoint 2010 with IIS 7.5
    • Go to the IIS settings , choose the Sharepoint site you need to configure, and double click on the "Authentication" icon

    • Enable the "Windows Authentication"
    • Click on "Providers..." and ensure that "NTLM" is in the "Enabled Providers" list
