Group access controls

ACLs can contain groups in addition to individual usernames. Groups can be created, managed and deleted by any user, using various options to the pts command. Group names created by users have the form user:groupname Wrapper scripts or aliases for some of these may be available.

pts_creategroup: Create a new group
pts_adduser: Add one or more users to a group
pts_removeuser: Remove a user from a group
pts_examine: List details of a user of group. Groups have their own permssion flags which retrict who can list the members, add or remove members etc.
pts_membership: List the members of a group
pts_delete: Delete a group.

The owner of a group determines who has rights to list membership, add users, remove users etc. The owner is initially the creator, but may be reassigned. The owner can be the group itself (all members can have administrative priviledges) or can be another group. For example, a smaller group of users can own (and have administrative priviledges) a larger group.
