When new users are configured who will need access to Slate (Admissions, Financial Aid, Marketing, Deans, Program Directors, etc.), they need to be added to the "Slate Implementation" group in Microsoft Azure.

This is done as follows:

1- Go to https://portal.azure.com/

2- Click "View" under "Manage Azure Active Directory"

3- Go to the "Slate Implementation" group at https://portal.azure.com/#view/Microsoft_AAD_IAM/GroupDetailsMenuBlade/~/Overview/groupId/6442d76a-058b-42f3-9fc7-063e60ea5953

4- Click on "Members" in the left Nav menu and add members

The Application for Slate which has been configured (apparently by Nathaniel) is under "Enterprise Applications" > Slate
