Managing User Accounts
7.8 Restricting the Use of Accounts
In the user’s account record of the UAF, the default value of a user’s priority is
4; for practical purposes, the minimum value is 0. Ensure that the priority for
timesharing users remains at the default. Note that if you give some users an
advantage over other users by raising their priorities, ragged performance results,
because the system reacts sharply to even small base priority differences.
7.9 Setting Up Special Accounts
As system manager, you might need to set up a variety of special accounts, such
as automatic login accounts, project accounts, and proxy accounts. The following
sections explain how to perform these tasks:
Task Section
Setting up an automatic login account with SYSMAN Section 7.9.1
Setting up a project account with ACL identifiers Section 7.9.2
Creating network proxy authorization files Section 7.9.4
Adding proxy accounts Section 7.9.5
Removing proxy accounts Section 7.9.6
Displaying proxy accounts Section 7.9.7
Controlling proxy logins Section 7.9.8
Section 7.9.3 explains what network proxy accounts are.
7.9.1 Setting Up an Automatic Login Account with SYSMAN
The System Management utility (SYSMAN) includes the functions of the
automatic login facility (ALF). Using SYSMAN ALF commands, you can set up a
terminal that automatically logs in a user to a certain user name. For example, a
terminal might be set up for the account INVENTORY, which automatically logs
in a user to a captive account when the user presses the Return key.
First, you must follow the steps described in the previous sections to create the
top-level default directory and to add the account. Then you can associate the
account with a particular terminal or port using the following format:
ALF ADD device user [/TERMINAL] [/PORT] [/PROXY] [/LOG]
where:
device is the terminal or port name that you want to assign to a user name.
Note that device must be a terminal name if you do not specify
qualifiers on the command line.
user is the account user name that you want to assign to a particular
terminal or port.
/TERMINAL causes SYSMAN to treat device as a terminal name. This is the default
behavior.
/PORT causes SYSMAN to treat device as a port name. If the port name
contains a special character such as a slash ( / ) or if it contains
lowercase letters that you want to preserve, you must enclose the
port name within quotation marks. Be aware that anything within
quotation marks is written literally to the ALF database file. For
example, if the actual port name contains uppercase letters as well
as special characters, be sure to specify uppercase letters within the
quotation marks. Otherwise, a mismatch will occur between the actual
port name and what is specified in the SYSALF.DAT file.
