If you look on the Microsoft SQL Server site you will see that there is a books on-line update dated January 2004.

You can tell if you need the update by looking at the documentation for the sp_addlogin stored procedure.

If example E for copying passwords says

CONVERT(VARBINARY(32),[Password])

instead of

CONVERT(VARBINARY(256),[Password])

then you need to update BOL.
