You can use Azure Active Directory with SAML-based SSO as an authentication source for your users to log in to WhosOnLocation. With SAML single sign-on, Azure AD authenticates to the application with the user's Azure or Microsoft 365 account.
WhosOnLocation has now been listed in the Azure AD App Gallery for your convenience. To set up SSO with Azure, you can install the WhosOnLocation app to your Active Directory instance through the Azure Portal.
For a complete tutorial on how to set this up, please refer to the Microsoft documentation.
