Audit Addlogin Event Class

The Audit Addlogin event class occurs when a Microsoft SQL Server login is added or removed.

If you set additional properties when the login is added, such as default database, the information about these properties will be found in the TextData column of this event. If you set these properties while adding a login, the Audit Login Change Property Event will not occur.

This audit event is for the sp_addlogin and sp_droplogin stored procedures.

This event class may be removed in a future version of SQL Server. It is recommended that you use the Audit Server Principal Management event class instead.
