derby.user.UserName

Function

Has two uses:

Creates users and passwords when derby.authentication.provider is set to BUILTIN.
Caches user DNs locally when derby.authentication.provider is set to LDAP and derby.authentication.ldap.searchFilter is set to derby.user.

Users and Passwords

This property creates valid clear-text users and passwords within Derby when the derby.authentication.provider property is set to BUILTIN. For information about users, see "Working with User Authentication" in the Derby Developer's Guide.

Database-Level Properties
When you create users with database-level properties, those users are available to the specified database only.

You set the property once for each user. To delete a user, set that user's password to null.
System-Level Properties
When you create users with system-level users, those users are available to all databases in the system.

You set the value of this system-wide property once for each user, so you can set it several times. To delete a user, remove that user from the file.

You can define this property in the usual ways-typically in the derby.properties file.

When a user name and its corresponding password are provided in the DriverManager.getConnection call, Derby validates them against the properties defined for the current system.

User names are SQL92Identifiers and can be delimited.
