SP or query to dump "password policy" checkbox for all logins
Here's the start of a report:

SELECT
    sp.name AS LoginName,
    sl.is_policy_checked AS IsPasswordPolicyEnforced
    FROM sys.server_principals sp
    LEFT OUTER JOIN sys.sql_logins sl ON sl.principal_id = sp.principal_id
    WHERE sp.type IN ('S', 'G', 'U');


Note that this property only applies to SQL logins.
