And then we need to either wait some time for system to unlock that account automatically or we must manually unlock an user account. After few wrong passwords, often 3, the account will be locked. However, more interesting problem arise when an user didnвЂ™t provide correct username or a password. After that, user have TGT associated with his username across whole Active Directory (AD) site.
