当 MUST_CHANGE 为 ON 时，不能关闭 CHECK_POLICY 和 CHECK_EXPIRATION 选项。 （微软 SQL 服务器，错误：15128）

An exception occurred while executing a Transact-SQL statement or batch.

The CHECK_POLICY and CHECK_EXPIRATION options cannot be turned OFF when MUST_CHANGE is ON. (Microsoft SQL Server, Error: 15128)

 

 

 

The fix for this is to change the password. You can do this via script like so:

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