---修改密码，并且将限制用户下次登录的时候(第一次登录)，强制要换一个新的口令：
---此过程可以完全模拟我们在标准用户的Form里面初始化用户的密码的动作！
---最后要说明的是，这个处理过程是通过研究标准创建用户的画面得出来的结果，所以，如果有需要，请放心使用！

-- instead of SYSDATE. last_logon_date should reflect the date the user last
-- logged in successfully, not the date the user‘s password was reset.
-- This does not regress the fix for bug 4690441 because in fnd_web_sec.disable_user
-- if last_logon_date is NULL, the last_update_date will be used which is the same
-- date of the sysadmin reset, so the effect is the same.
--
-- Reset password_date field to null to force password
-- expiration the next time user logs on.
