The correct details are saved in the PPRJ file itself once you’ve converted your project from Protege Files to Protege Database.
As part of that convert process, you specify the JDBC connection details as described in this help file:

Hi Victor,

Is your RHEL Linux providing you with a graphical user interface?
These parameters must be set as part of the Protege project file (PPRJ) and normally that is via the Project->Convert Project... menu option in the GUI

From what you've posted it looks like you need to provide the correct login credentials (username and password)
