4.4.2 MANAGEMENT (Cont.)
CONFIGURABLE PARAMETERS (Cont.)
Record logins For either Auditor option, if this fi eld is enabled, then each time a new login
occurs a message appears, giving the date, time and login name. E.G.
12/07/06 15:32:20 Login by Frederick Bloggs
Logouts are recorded in a similar way - e.g.
12/07/06 15:49:43 Logout by Frederick Bloggs
If the login or logout is via a ‘Bridge’ session ( section 6 ), the IP address of that
viewer appears in the login/logout message - e.g.
12/07/06 15:58:03 Login by (149.121.130.126)Engineer
Login Timout When set to zero, the login remains valid until changed. For any other value,
the user is logged out after the number of minutes entered here has elapsed
since the last time the screen was touched.
with unapplied changes This fi eld does not appear if the Login Timeout has been set to zero. For non-
zero time-out values, this allows the user to choose whether
a any unapplied changes are lost when the Login Timeout period has elapsed,
or
b the login timeout is ignored if there are any unapplied confi guration chang-
es.
Password Attempts For Active Directory users, this parameter is confi gured at the Active Directory
and the value set at the instrument is ignored.
For other users, this allows the user to limit to three, the number of attempt that
can be made to enter a password. The choices are ‘3 times’ and ‘unlimited’.
When set to 3 times, the user login is disabled after three incorrect attempts
to enter the password have been made. A ‘System Message’ appears on the
screen and is also sent to the ‘chart’:
12/07/06 13:20:42 User Frederick Bloggs, login disabled, invalid password
In order to re-enable the login, a user with Engineer access level must dese-
lect ‘Login Disabled’ in the ‘
Access ’ menu described in section 4.4.1, above.
Passwords expire For Active Directory users, this parameter is confi gured at the Active Directory
and the value set at the instrument is ignored.
For other users, this fi eld allows the user to set an expiry period of up to 999
days which applies to all passwords. The number of days remaining to expiry is
shown in the login page. If set to zero, then the expiry period does not apply.
Note: All required passwords MUST be changed within this number of days or all logins will be
disabled In this situation, the confi guration of the recorder will be available only to those with Ser-
vice Level access and in most cases, a call will have to be made to the recorder supplier or service
agency. (But see ‘
Password Change on Expiry’ , below)
Minimum Password Length For Active Directory users, this parameter is confi gured at the Active Directory
and the value set at the instrument is ignored.
For other users, this allows a minimum length of password to be entered (de-
fault = 0; minimum = 3). If an attempt is made to enter a new password with
fewer characters than the minimum, a warning message appears on the screen
(Invalid Password Length) and the new password is ignored.
Require Signing If this fi eld is enabled, then changes to the recorder operation, confi guration
(or any other item included in the history fi le) can be made only by those users
whose ‘Can Sign’ permission is enabled in the ‘
Access ’ menu described in sec-
tion 4.4.1 above. When ‘Apply’ is attempted, a ‘signature’ page appears which
requires the entry of the correct password for the selected user, and of a note
which would normally be used to give the reason for the change.
