FastClose Server Authentication Introduction
FastClose Server supports multiple ways of authentication so that users can use FastClose easily, more securely and with less admin by utilizing an external identity provider such as Windows authentication or OpenID Connect (OIDC).
FastClose supports the following ways to authenticate users:
Username and Password. Each user has their own username and password that is configured via the Admin app.
Windows Authentication. FastClose Server can use Windows Domain authentication (Kerberos) to authenticate all users. The domain and protocol ensure secure access for users with minimal administration but all users must be logged in to the same domain as the FastClose Server.
OIDC. FastClose Server has support to authenticate users using your external identity provider (IDP) utilizing OpenID Connect and OAuth 2.0. If your company already uses an IDP such as Microsoft or Okta then FastClose can use the same one for authenticating users.
Nextworld SSO. FastClose Server can support the SSO mechanisms provided by the Nextworld ERP such as OIDC and SAML.
The default authentication is Username and Password. If you are happy with this setting you may skip the remainder of this document.
Change Your Authentication Type
Important: Before you change your authentication type to OIDC or Nextworld SSO, you must already have created a user in FastClose who will be able to authenticate via that method and is a member of the Administrators group.
The Admin Setup page is where you configure your authentication type.
The following pages have more information and configuration for the different authentication types.
Password Sign In Page
If you cannot access the Admin web app after configuring it for SSO or you need to login as the default Administrator you should see the Password Sign In Page for more information.
