Privileges of System Administrators
System administrators with read privileges can examine the contents of any local
depot, but cannot update another depot's objects or profiles, and cannot create or
delete depots.
System administrators with write privileges can register new correspondents at their
node or remove them from the node. Registering a correspondent automatically
creates a depot for that correspondent, and removing a correspondent deletes that
depot. System administrators can also act on behalf of other correspondents. They
can, for example, change the profile of another correspondent (except for selected
elements that remain under TRANSFER control); create and delete folders; and create,
read, modify, and delete distribution lists at any depot at their node.
System administrators can also modify many system profile attributes to control such
factors as:
Enabling or disabling the external objects feature at the local node
Altering the system default language and character map used by TRANSFER
processes when these are not specified at the beginning of a standard TRANSFER
session
Altering the maximum package lifespan or minimum delivery window for all
packages sent from the node
Privileges of Other Correspondents
Correspondents, including system administrators at other nodes, have very limited
access to depots of other correspondents. A process that knows the name of a
correspondent can see whether that correspondent has a depot at the node; any
process can get a list of all correspondents at the node. Any correspondent can get the
names of distribution lists belonging to other correspondents and use the names of the
lists; however, a correspondent at one node cannot examine the members of a
distribution list at another node.
Correspondent A can use Correspondent B's distribution list without Correspondent
B's knowledge; Correspondent A, however, cannot change or delete that distribution
list. Correspondent A can examine the contents of Correspondent B's distribution list
only if the processes used by both correspondents are running at the same node.
