Azure AD Connect 1.1 (formerly DirSync) is now generally available for download. If you’ve been using Azure AD Connect, you’ll want to pay attention to the new features that come in 1.1.
This is the last time you need to manually upgrade Azure AD Connect. There is a new auto-update feature that will periodically perform upgrades.
More Frequent Synchronizations
In the past, the default sync interval was 3 hours. Now, you can schedule a sync to run as often as every 30 minutes, if desired.
Support for MFA
This is a big one. Previously, accounts that used multi-factor authentication could not be used with Azure AD Connect. This was a huge security risk because the account used by Azure AD Connect had to be a global administrator on your tenant. In the new release, MFA is now supported to better secure your service accounts.
You can now configure with OUs to synchronize with your tenant during the installation process. Previously, you had to install Azure AD Connect and then later filter the OUs in the Synchronization Service Manager.
You can also modify the user sign-in method after installation now. Previously, you had to choose this during the install of Azure AD Connect and didn’t have the option to modify it later without reinstalling.
