hi, yum updated your samba package. this means that /var/cache/samba/winbindd_privileged would have had its group permissions changed. you probably changed the permissions eg group radiusd when setting your radiusd up. this change will need to be done again.... or add radiusd to the group that owns that file.
radiusd -X will show somthing about winbind_privileged crap (literally!) alan - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
