The password was forgotten by the database administrator.
If the password of the database administrator is forgotten, there is no way to simply reset or read it out for security reasons.
There are now 2 possibilities how to proceed.
1. A user is fully authorized to access the database administrator -> then this user can change the password of the administrator. (is recommended)
2. You would have to create a new DB and therefore a new DB-Admin. After that one can only export the data of the users of the old database, to which one still has access, and import it into the new database.
