Note that Bitnami packages and configures already existing applications. However, we can only offer support and help on basic and most frequent application configurations. Always based on the default configuration or on our guides.

Do not hesitate to write us back if you have any other questions regarding the Bitnami solutions or their configuration.
I hope it helps.
