Permission denied Message at Login

After entering your login ID and password, you may get a Permission denied message and be returned to the login: prompt. This means that your login attempt has failed because an administrator has either locked your password, or terminated your account, or your password privileges have expired. In these situations you cannot log in until an administrator unlocks your password or reactivates your account or privileges. Consult your system administrator.
