Looks ok.

What is the point of this?  I see that it won't dereference that null
any more, but you really need to actually check that return value now.

Either that, or (and this may well be the better approach) simply check
that the paramaters are not null in the caller - becouse 95% of the time
you *know* its a valid sid.  (So add the check to the code that is
reading it from secrets.tdb).
