Subject: [PATCH 17/17] CVE-2018-16857 dsdb/util: Add better default
|
|
lockOutObservationWindow
|
|
|
|
Clearly the lockOutObservationWindow value is important, and using a
|
|
default value of zero doesn't work very well.
|
|
|
|
This patch adds a better default value (the domain default setting of 30
|
|
minutes).
