--- Comment #1 from Quanah Gibson-Mount quanah@openldap.org --- It additionally appears that this new 2.5 functionality is further broken in that setting lastbind to false requires a restart for it to take effect.
I'd also note that unlike the lastbind overlay, there's no ability to set a precision value which means that this setting can be problematic in high traffic replicated environments.
