REDHAT-BUG-1477669: Medium severity red hat directory server vulnerability
The directory server password lockout policy prevents binds from operating once a threshold of failed passwords has been met. If attacker during this lockout binds with the correct password, a different error code is returned. This means that attacker has no ratelimit or penalty during the account lock, and can continue to attempt passwords via bruteforce.
