Control of the Logon Dialog
Control of the Logon Dialog
When you add a terminal definition record, the Safeguard software takes over control
of the logon dialog at that terminal. In earlier RVUs, certain extended features, such as
warning of a pending password expiration, were available only at a Safeguard terminal.
Effective with D30 product versions, the TACL command interpreter also provides
these logon features when Safeguard is running on the system.
From the user perspective, the Safeguard logon dialog is the same as the TACL logon
dialog. As long as Safeguard is running on your system, all security controls and logon
features, such as the password expiry grace period, are enforced whether or not the
terminal is defined as a Safeguard terminal.
For more information about the logon dialog at a Safeguard terminal, see the
Safeguard User's Guide.
Starting a Command Interpreter
When you add a terminal definition record, you can specify that a particular command
interpreter be started automatically at that terminal after user authentication. A
command interpreter can also be specified in a user authentication record and in the
Safeguard configuration record.
The Safeguard software resolves any conflicts among these records by searching for a
command interpreter specification in the following order: user record, terminal record,
Safeguard configuration record. The first specification found during the search is the
command interpreter that is started after user authentication. Therefore, a command
interpreter specified in a user authentication record always takes precedence over one
specified in a terminal record or Safeguard configuration record.
If no command interpreter is specified in the user authentication record or in the
terminal definition record, the command interpreter defined in the Safeguard
configuration record is used. Unless you use the ALTER SAFEGUARD command to
Table 7-2. TERMINAL Command Summary
