derby.authentication.native.passwordLifetimeThreshold

Function

Specifies the threshold that triggers a connection-time warning that a password is about to expire. The threshold must be a DOUBLE value greater than 0.0.

To avoid locking out the super-user, the password of the database owner of a credentials database never expires.

A warning is raised when a user logs in and the remaining lifetime of that user's password is less than this proportion of the maximum password lifetime. That is, Derby raises a warning when the remaining lifetime of a password is less than (derby.authentication.native.passwordLifetimeThreshold * derby.authentication.native.passwordLifetimeMillis).

To set the lifetime of the password, use the derby.authentication.native.passwordLifetimeMillis property.

Syntax

derby.authentication.native.passwordLifetimeThreshold=proportion

Default

0.125 (1/8).

Example

-- system-wide property
derby.authentication.native.passwordLifetimeThreshold=0.2

-- database-level property
CALL SYSCS_UTIL.SYSCS_SET_DATABASE_PROPERTY(
    'derby.authentication.native.passwordLifetimeThreshold', '0.2');

Dynamic or static

Static. For system-wide properties, you must reboot Derby for the change to take effect. For database-wide properties, you must reboot the database for the change to take effect.
