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