The CHECK_EXPIRATION option cannot be used when CHECK_POLICY is OFF.

Error Message:
Msg 15122, Level 16, State 1, Line 2
The CHECK_EXPIRATION option cannot be used when CHECK_POLICY is OFF.

Severity level:
16.

Description:
This error message appears when you try to use a CHECK_EXPIRATION = ON option in a CREATE LOGIN statement while die CHECK_POLICY option is deactivated.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Errors of the Severity Level 16 are generated by the user and are corrigible by the user. The statement cannot be executed this way. CHECK_POLICY must be activated for CHECK_EXPIRATION to make sense.

Versions:
This error message was introduced with SQL Server 2005.

Example(s):
USE Master;
CREATE LOGIN MyLogin
 WITH PASSWORD = 'ABC',
 CHECK_POLICY = OFF,
 CHECK_EXPIRATION = ON;
GO

Remarks:
In the above example we try to create a login for which the CHECK_POLICY option is set to FALSE, while CHECK_EXPIRATION is set to TRUE. This raises the error.
