If global groups have been registered under Windows server, you can limit the use of functions for
each global group.
You need to create global groups in the Windows server in advance and register in each group the
users to be authenticated. You also need to register in the machine the functions available to the
global group members. Create global groups in the machine by entering the names of the global
groups registered in the Windows Server. (Keep in mind that group names are case-sensitive.)
Then, specify the machine functions available to each group.
If global groups are not specified, users can use the functions specified in [*Default Group]. If
global groups are specified, users not registered in global groups can use the functions specified in
[*Default Group]. By default, all functions are available to *Default Group members. Specify the
limitation on available functions according to user needs.
