Perspective 5.1 and later versions continue to support Windows authentication (non-SAML authentication); however, it is available for Perspective only and can no longer be enabled through Service Manager.
IMPORTANT NOTE: If you wish to use single sign-on authentication for all Perspective modules (Perspective, Dispatch, Dashboard, and/or Web Portal) you must enable SAML authentication. See the What is SSO and How Do I Get It? article for more information.
Open the config file. By default, this file is located at C:\inetpub\wwwroot\Perspective5.1\PerspectiveServices.
Locate the <WindowsAuthentication> tag.
Delete the false value in the tag and replace it with true.
Note: You cannot enable both Windows authentication and SSO in the Perspective_default.config file by changing the <SSOAuthentication> tag’s value to true.
Save the file.
Reset IIS to complete the configuration.
