Managing User Accounts
Before your computer will allow incoming Timbuktu connections, you must grant user access to one or
more Timbuktu services. Use the Guest User, NT Users, and Registered Users tabs in the Timbuktu Host
Configuration Utility to create user accounts and assign access privileges. You can allow one-time-only
access by enabling the Ask for Permission feature, assign certain services to all Guest Users, and grant
permanent access privileges to individual NT Users and Registered Users. You can add or remove access
privileges or user accounts at any time.
Note that having a Timbuktu account on one computer does not give a user the ability to connect to any
other Timbuktu computer. Each Timbuktu Host controls its own access permissions.
Before You Create User Accounts
As you configure the Guest User and individual user accounts, keep the following points in mind.
• The Control service allows the other Timbuktu user to perform any of the tasks that you can per-
form when you are logged on to your computer. This means that a user with the Control privilege
may be able to run applications; create, modify, or delete files without restriction; and erase data
from your computer. The Control privilege, therefore, should be granted with caution.
• If you grant Ask for Permission access to a user requesting the Exchange service, you automatically
grant the user access to all three Exchange sub-services: Exchange (Read), Exchange (Write) and
Exchange (Delete).
• If you decide that a certain service—for example, Control or Exchange—should not be available to
any user at any time, you must remove that service from Guest User access and from the list of
privileges for every user account. You may also disable the Ask for Permission feature.
• The services you assign to Guest Users are automatically assigned to NT Users and Registered Users
as well. You cannot withhold a privilege from a NT User or Registered User if that privilege is
assigned to Guest Users.
When you have finished configuring Timbuktu user accounts, shut down and restart the Timbuktu Host as
described in
“Starting and Shutting Down Timbuktu” on page 10 . When it restarts, the Timbuktu Host
will apply your new settings and resume listening for incoming connections.
Guest Users, NT Users, and Registered Users
Timbuktu allows you to specify many different levels of remote-user access. You can allow all Timbuktu
users to access certain services, and limit other services to password-authenticated users or make them
entirely inaccessible.
Guest Users and Ask for Permission Users
All Timbuktu users that do not have NT User or Registered User accounts are treated as Guest Users. The
Guest User is a single account that does not require the user to supply access credentials, and whose
access privileges are available to anyone who connects to your computer with Timbuktu. For this reason,
Guest Users are usually assigned a limited range of Timbuktu services. Services such as Send and Notify,
which allow minimal remote interaction with your computer, are often assigned to Guest Users. Services
such as Control and Exchange, which may allow complete access to your computer, are almost never
assigned to Guest Users. Exercise caution when granting a service to Guest Users.
