Explanation:
The following describes user experiences with single sign-on from within the network:
* (1) Work computer on a corporate network: When users are at work and signed in to the corporate network, single sign-on enables them to access the cloud service without signing in again.
If the user is connecting from outside your company’s network or accessing services from particular devices or applications, such as in the following situations, you must deploy an STS proxy. If you plan to use AD FS for your STS, see Checklist: Use AD FS to implement and manage single sign-on for more information about how to set up an AD FS proxy.
* (2) Home or public computer: When the user is using a computer that is not joined to the corporate domain, the user must sign in with their corporate credentials to access the cloud service.
* (3) Smart phone: On a smart phone, to access the cloud service such as Microsoft Exchange Online using Microsoft Exchange ActiveSync, the user must sign in with their corporate credentials.
* Work computer, roaming: Users who are logged on to domain-joined computers with their corporate credentials, but who are not connected to the corporate network (for example, a work computer at home or at a hotel), can access the cloud service.
* Microsoft Outlook or other email clients: The user must sign in with their corporate credentials to access their email if they are using Outlook or an email client that is not part of Office; for example, an IMAP or POP client.
