Applying Overrides to All Members of a Group
To apply overrides to all members of a specific group, create an override entry that contains the group's UNIX ID as a key and the items to override. For groups, you can override passwords, GECOS information, home directories, and shells. For example, the following entry makes /sonata/piano the home directory for all members of the group that is identified by UNIX ID 356:
:::356::/sonata/piano:
Be sure not to include the principal_name or principal_uid keyfields. If you do, the principal name or UNIX ID that you supply will be used as a keyfield, and the group UNIX ID will be used to override that principal's group affiliations.
