Should these files be setuid?

Hmm ... When I try this here, what I get is:

: rpm -V pam
..?.....   /sbin/pam_filter/upperLOWER
:

This would seem to imply that there's something suspicious about this
file,  but what?  The ..?.....  presumably is some sort of indicator,
and looks like a list of flags.  I checked with "man rpm", and all  I
find is:

   ...   Among other things, verifying compares the
   size, MD5 sum, permissions, type, owner and group of  each
   file.  Any discrepencies are displayed.

so  this  is  obviously  not  a  list of the meanings of the dots and
question mark.  I don't seem to find any other clues anywhere.

Any idea how I might learn what, if anything, is wrong here?
