------------------------------------
Summary: Native user authentication:
SYSCS_UTIL.SYSCS_MODIFY_PASSWORD accepts old password
Key: DERBY-5748
URL: https://issues.apache.org/jira/browse/DERBY-5748
Project: Derby
Issue Type: Improvement
Components: Services
Affects Versions: 10.9.0.0
Reporter: Dag H. Wanvik
Modifying the password to the same as the old one will reset the timeout
specified in derby.authentication.native.passwordLifetimeMillis.
This means that a lazy user can subvert the security policy embodied in the
timeout. It would be an improvement to require a different one.
Of course, we don't currently have any password strength checking either, so it
may not be worth just implementing this change without making some configurable
strength checking also.
