The Vanta O365 enterprise application for Microsoft Office 365 allows you to enable SSO features for users managed in your Office 365 environment, creating frictionless login experience.

 

This guide assumes you are using Office 365 as your Primary IDP, and the integration has been connected in your Vanta instance.

 

Prerequisites

 

Procedure

  • Login to Azure and navigate to the Enterprise Applications page

  • Then click Users and Groups, and then select the users you want to assign the Vanta app to. 
    If you want the application to be applied to all users, then it's recommended to select the 'All Users' group as seen in the screenshot below, as this will also include future uses added to the group.

Common Issues

Resolution

  • The most common cause for this error is the "Vanta O365" has not been assigned to that users profile in Azure, or they are not assigned to the group that automatically provisions the app.

    Check that the user is:
    • assigned to the group where the Vanta O365 app was applied
    • has the app assigned to their Azure AD user profile
    • Office365 is the primary source of their employment information (see here on how to check this)
    • Is using the email address registered to their Vanta profile
