IBM Aspera HST Admin Manual page 36

Ensure that you have an existing user group on your operating system, or create a new user group. Please refer
to your operating system's documentation for information on creating user groups. HST Server reads group
information from the following file:
/etc/group
2. Add the user group to your Aspera transfer product
When a transfer group is specified, it overwrites global settings and applies group configuration to corresponding
users. To add group-specific transfer settings, you can use asconfigurator commands with the following
syntax:
# asconfigurator -x "set_group_data;group_name,groupname;parameter,value"
For more information on available settings, see
references in the table below.
