User Sign-In Options:
- Password Hash Synchronization (selected by default): This option synchronizes users’ on-premises Active Directory (AD) passwords with Microsoft Entra ID (previously Azure AD), allowing users to use the same passwords to sign in to cloud services like Microsoft 365.
- Pass-through authentication: This enables on-premises authentication, where user passwords are validated against the on-premises Active Directory without storing password hashes in Microsoft Entra ID.
- Federation with AD FS: This option uses Active Directory Federation Services (AD FS) to handle authentication, providing more control over the authentication process.
- Federation with PingFederate: Allows for federated sign-in using PingFederate as the identity provider.
- Do not configure: This option disables any specific sign-in configuration.
Single Sign-On (SSO) Option:
There is an additional checkbox labeled “Enable single sign-on”. This option, when selected, enables single sign-on for users on corporate networks, reducing the need for them to repeatedly enter their credentials when accessing Microsoft cloud resources.
The options listed provide different levels of integration between on-premises environments and Microsoft cloud services, catering to different authentication requirements and security configurations based on organizational needs.
