Hi@Kiran Kumar Maddipati
Welcome to Microsoft Q&A platform and thanks for posting your question here.
Yes, it is possible to access an on-premises MariaDB database via SSL-based authentication in Azure Data Factory. You can use the Self-hosted Integration Runtime to connect to the on-premises MariaDB database.
To connect to the on-premises MariaDB database via SSL-based authentication, you need to obtain the SSL certificate and configure the connection string accordingly. You can download the SSL certificate from the MariaDB server and save it to a local drive.
Need to configure the connection string in the SHIR to include the SSL certificate path and other SSL-related parameters. You can refer to the Azure documentation on [how to configure SSL connectivity in your application to securely connect to Azure Database for MariaDB.
Once you have configured the connection string, you can use the ADF MariaDB connector to connect to the on-premises MariaDB database via the SHIR.
