Adding and Removing Group Members

Adding and Removing Group Members
	Chapter 13. Administering the Protection Database

Users and machines can be members of groups; groups cannot belong to other groups. Newly created groups have no members at all. To add them, use the pts adduser command; to remove them, use the pts removeuser command.

To add users and machines to groups

Verify that you belong to the system:administrators group, which enables you to add members to a group regardless of the setting of its fourth (a) privacy flag. By default the group's owner also has the necessary privilege. If necessary, issue the pts membership command, which is fully described in To display the members of the system:administrators group.
```
   % pts membership system:administrators
```
Issue the pts adduser command to add one or more members to one or more groups.
```
   % pts adduser -user <user name>+ -group <group name>+
```
