MOD

Description (Required):

We are looking into the use of OCI Vault to store credentials.

Having followed the blog @ https://www.ateam-oracle.com/post/access-secrets-in-oci-vault-from-the-autonomous-database-with-the-plsql-sdk - we can access secrets from an OCI Vault.

However any database schema with a resource principal can access any secret in the vault.

Use Case and Business Need (Required):

Use OCI Vault to store database and API credentials for use in CI/CD pipelines and allow subset access to developers.

Allow fine-grained access such that certain schemas, i.e ADMIN have full access and other application or developer schemas have subset access.
