> Add Azure Entra Database Password Provider
> ------------------------------------------

> Key: NIFI-16367
> URL: https://issues.apache.org/jira/browse/NIFI-16367

> Issue Type: New Feature

> NiFi DBCPConnectionPool supports DatabasePasswordProvider controller services
> for obtaining short-lived database credentials, with existing implementations
> for AWS RDS IAM and Google Cloud SQL IAM authentication.
> The goal is to add an AzureEntraDatabasePasswordProvider controller service
> to the Azure extension bundle. The provider should:
> * Use a configured AzureCredentialsService to obtain Azure credentials.
> * Request a Microsoft Entra access token for the public Azure OSS RDBMS
> scope:
> [https://ossrdbms-aad.database.windows.net/.default]
> * Return the access token as the database password when DBCP creates a
> physical JDBC connection.
> * Support Azure Database for PostgreSQL Flexible Server and Azure Database
> for MySQL Flexible Server.
> * Resolve the current TokenCredential for each password request so that
> credential-service reconfiguration is honored.
> * Reject null, blank, or expired tokens using sanitized error messages that
> do not expose credentials or upstream exception details.
> * Provide configuration verification that exercises token acquisition using
> the OSS RDBMS scope.
> * Include controller-service registration, focused unit tests, and operator
> documentation for PostgreSQL and MySQL JDBC configuration.
> This approach uses the existing AzureCredentialsService abstraction, so it
> supports the available Azure credential strategies, including workload
> identity federation, without coupling the database password provider to a
> particular external identity issuer.
> Azure SQL Database is outside the scope because its JDBC driver requires an
> access-token or driver-native authentication configuration rather than the
> DatabasePasswordProvider password mechanism.
> Follow-up improvements will be made to support SQL Server which requires a
> slightly different handling.
