In order to use Windows authentication, four requirements must be met:

• Each Windows user account must be linked to a person in AssetWise.
• Each Windows user account must be a valid network log on account for the IIS server.
• The virtual directory must have anonymous access turned off.
• Web.config in the ALIM Web virtual directory must have the authentication element's mode attribute set to "Windows", and the identity element's impersonate attribute set to "true".

The ALIM Web Application Manager automatically ensures that the third and fourth requirements are met when the ALIM Web virtual directory is created, but it is up to the administrator to ensure that the first and second are correctly configured.
