Yes you are correct, I do not write 'C' and read it just a bit more :-D

The problem is that it should (by my reading) return either 
'NT_STATUS_OK' or what 'map_nt_error_from_unix(errno)' would return and 
as far as I can see, that cannot return 'NT_STATUS_INVALID_OWNER'

To me, this looks like,for some reason, the users restore privilege is 
being ignored, that block of code is being ignored and it is dropping 
down to the block of code where the user supplied is checked against the 
actually user that is connected and if they do not match, then you get
