1 /LEFTOVERS
Use of the /LEFTOVERS qualifiers causes the DIRBOT to use .OLD LDIF files for any directories that do not presently have new LDIF files present. That is, specifying /LEFTOVERS is equivalent to having BEST_WITHIN set to an infinite time for every directory.

/UPDATE=dirlist /NOUPDATE=dirlist By default, if neither /UPDATE nor /NOUPDATE is specified, the DIRBOT sends its updates resulting from processing as normal, as specified in its option file.

Specifying /NOUPDATE=(dir1,dir2,...) will cause the updates to be sent to all directories except the specified list of directories dir1,dir2,....
