How are yo starting mysql? You need to explicitly set the login class.
Somthing like
su -c mysql root /usr/local/bin/mysqld_safe ...

Otto is right. Here is my /etc/postgresql.rc script, which should give
you some ideas for managing mysql (notice ``SU'').
#!/bin/sh
exec >&2
DATA=/var/postgresql/data
LOG=/var/postgresql/log
CMD=$1
PUSR=_postgresql
PCLS=postgresql
CTL=/usr/local/bin/pg_ctl
SU="su -l -c $PCLS $PUSR -c"
userinfo -e $PUSR || { echo "$PUSR user nonexistent."; exit 1; }
grep -q "^${PCLS}:" /etc/login.conf || { echo "$PCLS class
nonexistent."; exit 1; }
[ -x $CTL ] || { echo "$CTL not executable."; exit 1; }
case $CMD in
stop|reload|status)
$SU "exec $CTL $CMD -D $DATA"
;;
start|restart)
$SU "exec $CTL $CMD -D $DATA -l $LOG"
chmod 644 $LOG
;;
*)
echo "usage: $0 stop|restart|reload|status|start (will run as
$PUSR)"
;;
esac
