MULTIMASTER DATABASE FOR IDENTITY AND ELECTRONIC MAIL IN DDIL ENVIRONMENTS

Abstract:

The present invention generally relates to systems and methods for providing an enterprise user with an electronic identity and an electronic mailbox when the user has denied, degraded, intermittent, or latent network connectivity. In aspects, a database limited to a single user containing the user's electronic identity and electronic mailbox is provided. The single user database is replicated using a multi-master replication scheme across the cloud and on-premises servers. When a user is entering an environment with denied, degraded, intermittent, or latent network connectivity ("DDIL"), the single user database is replicated to a DDIL server. The user is provided access to their electronic identity and electronic mailbox in the single-user database via the DDIL server during periods of denied, degraded, intermittent, or latent network connectivity. The single user database can be replicated across the cloud/on-premises servers during periods when network connectivity is established and adequate for replication.
