Looks like the winbind errors were a false alarm as I have now removed libpam-
winbind and now the error is just:

Jul  4 20:18:52 Rachael sudo: pam_unix(sudo:auth): conversation failed
Jul  4 20:18:52 Rachael sudo: pam_unix(sudo:auth): auth could not identify 
password for [mfraser]
Jul  4 20:19:10 Rachael smbd: pam_unix(samba:session): session closed for user 
nobody

If I use kdesudo partitionmanager 
Jul  4 20:20:43 Rachael sudo:  mfraser : TTY=pts/4 ; PWD=/home/mfraser ; 
USER=root ; COMMAND=/usr/bin/partitionmanager
Jul  4 20:20:43 Rachael sudo: pam_unix(sudo:session): session opened for user 
root by mfraser(uid=0)
