In case you missed the official announcement on June 3, 2013, we have some great news for customers using the Windows Azure Active Directory Sync tool. You now have the option to leverage a new feature that synchronizes your on-premises passwords to your Office 365 accounts.
Password Hash Sync is a feature of the Windows Azure Active Directory Sync tool that synchronizes user passwords from your on-premises Active Directory to Windows Azure Active Directory (“Azure AD”). Once the passwords have synchronized, users in your organization can logon to their internal workstations or applications and their Azure Active Directory services (such as Office 365, InTune, CRM Online, etc.) using the same password. This is different than Single Sign-On (SSO) as there is no token sharing / exchange, this means that Windows Azure AD will be providing authentication and authorization of the user based on the synchronized account and password. That leads to the obvious question, what if you are already using a Single Sign-On solution such as AD FS? We’ll cover switching in our next post.
