add group script (G)
This is the full pathname to a script that will
be run AS ROOT by smbd
8 when a new group is
requested. It will expand any
%g to the group name passed.
This script is only useful for installations using the
Windows NT domain administration tools. The script is
free to create a group with an arbitrary name to
circumvent unix group name restrictions. In that case
the script must print the numeric gid of the created
group on stdout.
