Specify user groups that are always treated as local when looking up group information, for example, when displaying file ownership.
You can type the list of local group names not stored in Active Directory, separated by a space. This list is then used to disable looking up account information in Active Directory for the groups specified, which results in faster name lookup service for system group accounts such as tty and disk.
