The Administrator account is unable to login to the Enforce Server.
Too many consecutive incorrect passwords were used attempting to login as the Administrator.
The Administrator account will be unlock after the time specified in com.vontu.manager.password.administrator.lockout.expiration elapses, 60 minutes by default.
NOTE: In order to complete the account's unlocking, the Built-in Administrator needs to successfully log into Enforce after the lockout expiration time expires. Without a successful login, the DLP system will still treat the Administrator account as locked, which can impact functionality such as execution of Enforce-launched Response Rule actions.
