[20141124]sql server密码过期，通过SSMS修改策略报错

背景：

     新建了用户，没有取消掉强制密码策略

     修改掉策略报错

错误：

    The CHECK_POLICY and CHECK_EXPIRATION options cannot be turned OFF when MUST_CHANGE is ON.

使用代码修改：

    USE Master
    GO
    ALTER LOGIN [somelogin] WITH PASSWORD = ‘samepassword’
    GO
    ALTER LOGIN [somelogin] WITH
    CHECK_POLICY = OFF,
    CHECK_EXPIRATION = OFF;
