-g gid
The numerical value of the group's ID. This value must be
unique, unless the -o option is used. The value must be non-
negative. The default is to use the smallest ID value greater
than 1000 and greater than every other group.
-a
add an automatic Security ID for the group (SID).
The rid of the group is calculated from the gidNumber of the
group as rid=2*gidNumber+1001. Thus the resulted SID of the
group is $SID-$rid where $SID and $rid are the domain SID and
the group rid
-b
the group is also a AIX group
-o
gid is not unique
-p
print the gidNumber to stdout
-s sid
set the group SID.
The SID must be unique and defined with the domain Security ID
($SID) like sid=$SID-rid where rid is the group rid.
-r rid
set the group rid.
The SID is then calculated as sid=$SID-rid where $SID is the
domain Security ID.
-t group type
set the NT Group type for the new group. Available values are
2 (domain group), 4 (local group) and 5 (builtin group).
The default group type is 2.
