      Bug report

      For bug reports, provide this information, please:

      When starting a connector with the Maria Db connector, I face an issue regarding the sslmode property.

      As per the documentation, database.ssl.mode can have the values `disabled`, `preferred`, `required`, `verify_ca` and `verify_identity`. This is true for mysql databases. 

      But mariadb expects other values. As per the documentation, they are `disable`, `trust`, `verify-ca`, `verify-full`. 

      When trying to use these values, I get the error:

      There is an issue with the connector.Code: InvalidInput.InvalidConnectorConfigurationMessage: The connector configuration is invalid. Message: Connector configuration is invalid and contains the following 1 error(s): The 'database.ssl.mode' value is invalid: Value must be one of verify_identity, disabled, preferred, required, verify_ca

      When trying to use the mysql ones, I get authentication problems. 

      With preferred

      Is this expected and is there a workaround for this?

      What Debezium connector do you use and what version?

      mariadb 2.7.1

      What is the captured database version and mode of deployment?

      (E.g. on-premises, with a specific cloud provider, etc.)

      AWS Mariadb

      Do you see the same behaviour using the latest released Debezium version?

      This is also in the latest branch.
