My first instinct would be to rebuild su without PAM and see if that
makes the problem go away. If it does, check if your PAM "config"
files have deviated from the default (while it's possible to
successfully edit them, only dedicated PAM experts seem to be able to
do so reliably) and also check if you've accidentally turned on
