Lock a remote user account based on LDAP after X login failures.

In order to be compliance with PCI standars we have to apply a lock account after X login failures.


Our environment has two BIG IP VE - Adv WAF in Sync-Only mode and they are using remote authentication based on LDAP (Windows AD).


How can we achieve the desired state? Is it possible while using remote authentication?


We checked the article below, but it seems not to work for our scenario.


Thank you.

    Have a good one.
