Derby provides a simple, built-in repository of user names and passwords.
To use the built-in repository, set derby.authentication.provider to BUILTIN. Using built-in users is an alternative to using an external directory service such as LDAP.
derby.authentication.provider=BUILTIN
You can create user names and passwords for Derby users by specifying them with the derby.user.UserName property.
derby.user."FRed"=java
