Microsoft Active Directory is an on-premise service.
Invotra connects to Microsoft Active Directory meaning that when your users are logged in to their Microsoft account, they are automatically authenticated into Invotra. This means that your users do not need to enter an additional password to access Invotra, as long as they are logged into their Microsoft account.
AzureAD is a cloud service.
Invotra connects to Azure AD, offering the same benefits and functionality that are found with Microsoft Active Directory – as long as your users are logged in to the Microsoft AzureAD, they will be authenticated into Invotra.
