"...In Oracle Database installations on which Oracle Database Vault is installed, the connector can be used to grant and manage authorization to Oracle Database Vault realms. The connector treats access to Oracle Database Vault realms as an entitlement. You can use the connector to provision database users with access to multiple realms with different levels of access.."
but after setup database vault and run successfully direct provisioning using dbum connector, I could not grant access to database vault realms. As far as I understood the connector should present database vault realms as entitlements, but i did not find any schedule task or lookup to enable this feature.
