EBS 11i的密碼原則，從 profile-->System去改
Signon Password Failure Limit：
輸入錯誤次數就會鎖住帳號，但是我在11i內測試未成功，網路上有人提到要上patch及額外的設定
The Signon Password Failure Limit profile option defines the maximum number
of login attempts before the user’s account is disabled.
Signon Password Hard to Guess：
是否啟用較複雜的密碼原則，也就是密碼的設定有較多的限制
密碼至少要有一個字母及一個數字、密碼不能有帳號且密碼中的字母不能有重複。
Set this Profile Option to Yes to ensure that they will be "hard to guess."
A password is considered hard-to-guess if it meets this requirements:
• The password contains at least one letter and at least one number.
• The password does not contain the username.
• The password does not contain repeating characters.
Signon Password Length：
密碼容許的最小長度
Signon Password Length defines the minimum length of the password. Te default is 5 characters
Signon Password No Reuse：
使用過的密碼需多少天後方能再使用，0表示不限制
This profile option specifies the number of days before any previously given password can be reused.
