240smbldap-groupmod - Modify a group
241
242=head1 SYNOPSIS
243
244smbldap-groupmod [-g gid [-o]] [-a] [-r rid] [-s sid] [-t group type]
245 [-n group_name ] [-m members(,)] [-x members (,)] group
246
247=head1 DESCRIPTION
248
249The smbldap-groupmod command modifies the system account files to
250reflect the changes that are specified on the command line.
251The options which apply to the smbldap-groupmod command are
252
253-g gid The numerical value of the group's ID. This value must be
254 unique, unless the -o option is used. The value must be non-
255 negative. Any files which the old group ID is the file
256 group ID must have the file group ID changed manually.
257
258-n group_name
259 The name of the group will be changed from group to group_name.
260
261-m members
262 The members to be added to the group in comma-delimeted form.
263
264-x members
265 The members to be removed from the group in comma-delimted form.
266
267-a
268 add an automatic Security ID for the group (SID).
269 The rid of the group is calculated from the gidNumber of the
270 group as rid=2*gidNumber+1001. Thus the resulted SID of the
271 group is $SID-$rid where $SID and $rid are the domain SID and
272 the group rid
273
274-s sid
275 set the group SID.
276 The SID must be unique and defined with the domain Security ID
277 ($SID) like sid=$SID-rid where rid is the group rid.
278
279-r rid
280 set the group rid.
281 The SID is then calculated as sid=$SID-rid where $SID is the
282 domain Security ID.
283
284-t group type
285 set the NT Group type for the new group. Available values are
286 2 (domain group), 4 (local group) and 5 (builtin group).
287 The default group type is 2.
288
289=head1 EXAMPLES
290
291smbldap-groupmod -g 253 development
292 This will change the GID of the 'development' group to '253'.
293
294smbldap-groupmod -n Idiots Managers
295 This will change the name of the 'Managers' group to 'Idiots'.
296
297smbldap-groupmod -m "jdoe,jsmith" "Domain Admins"
298 This will add 'jdoe' and 'jsmith' to the 'Domain Admins' group.
299
300smbldap-groupmod -x "jdoe,jsmith" "Domain Admins"
301 This will remove 'jdoe' and 'jsmith' from the 'Domain Admins' group.
