7 <para>This specifies a UNIX group name that will be
8 assigned as the default primary group for all users connecting
9 to this service. This is useful for sharing files by ensuring
10 that all access to files on service will use the named group for
11 their permissions checking. Thus, by assigning permissions for this
12 group to the files and directories within this service the Samba
13 administrator can restrict or allow sharing of these files.</para>
15 <para>In Samba 2.0.5 and above this parameter has extended
16 functionality in the following way. If the group name listed here
17 has a '+' character prepended to it then the current user accessing
18 the share only has the primary group default assigned to this group
19 if they are already assigned as a member of that group. This allows
20 an administrator to decide that only users who are already in a
21 particular group will create files with group ownership set to that
22 group. This gives a finer granularity of ownership assignment. For
23 example, the setting <filename moreinfo="none">force group = +sys</filename> means
24 that only users who are already in group sys will have their default
25 primary group assigned to sys when accessing this Samba share. All
26 other users will retain their ordinary primary group.</para>
29 If the <smbconfoption name="force user"/> parameter is also set the group specified in
30 <parameter moreinfo="none">force group</parameter> will override the primary group
31 set in <parameter moreinfo="none">force user</parameter>.</para>
