Organizational structure or regional compliance requirements often cause organizations to provision users in different directories. For customers provisioning users across several Azure AD directories, Microsoft recently released Azure AD Cross Tenant Sync to General Availability (Cross-Tenant Synchronization for seamless application access is now generally available! – Microsoft Community Hub). Unfortunately, a few shortcomings (e.g. lack of sovereign cloud support in China and USGov, lack of complex sync support) make this feature not (yet) usable by some customers. If there are other features blocking your organization, please let us know!
For customers provisioning users to sovereign clouds or with complex sync topologies, the Mindline Identity Bridge provides a simple, scalable, future-proof solution for efficiently provisioning users across identity stores. Unlike other sync approaches, the Mindline Identity Bridge uses Azure AD B2B so can be seamlessly removed as the Azure AD cross-tenant synchronization feature set matures.
