TYPO3 Core

Situation

• LocalConfiguration.php contains (incomplete) database credentials: some missing information (e.g. password) and there is no database with the configured name
• Install Tool is invoked and asks for DB credentials
• no matter what credentials are entered, an error is shown; basically, the user is deadlocked at that point w/o manual intervention in the config file

Observed behaviour

• after entering (correct) credentials, an error "Database connect not successful – Connecting to the database with given settings failed. Please check." is shown

Expected behaviour

• Proceeding to the next step where the database can be chosen or created

How to reproduce

• Take an existing, configured installation
• Open LocalConfiguration.php, delete the "password" entry of the default DB connection there and change the database name to something that does not exist
• Open the install tool. It should ask for database credentials.
