Yesterday Microsoft Released a new version of Azure AD Connect, which is now incremented to version 1.1.371.0.
I was first released as build 1.1.370.0 and then a day later build 1.1.371.0, which had a fix in it.
This new December update includes the following improvement:
- Pass-through Authentication (in Preview).
This new feature is not available when using the Auto update feature of AD Connect.
