NetLinx Security within the Web Server
45
NI-3101-SIG Signature Series NetLinx Integrated Controller
If a user is not currently logged-into the Master (
via the initial Login screen
) and they attempt to access a
feature wherein authentication is required, they are prompted with a message to log into the Master (via
the
Log In
button) (FIG. 31). After the user’s information and rights are confirmed, the login process is
successfully completed and the button changes state and displays
Log Out
. A user must be logged into
the system before their associated rights can be activated for the current session.
There is no limit to the number of concurrent logins allowed for a single user. This feature facilitates the
creation of a single user
(which is really an ICSP device such as a touch panel)
that is provided to a
number of ICSP devices using the same login to obtain access to the Master.
As an example, if you had 50 devices connected to a Master, you would not have to create 50
individual user accounts-one for each device. Instead, you only need to create one to which all
50 devices use for access.
By default, the NetLinx Master creates the following accounts, access rights, directory associations, and
security options:
Security Options: FTP Security - Enabled
Admin Change Password Security - Enabled
All other options - Disabled

Authentication is based upon matching the user’s data to pre-configured username
and password information, and then assigning the rights assigned to that user.
The maximum length of a username or password is 20 characters. The minimum
length of a username or password is four characters. Characters such as
#
(pound)
&
(ampersand) and
’ "
(single and double quotes) are invalid and should not be used in
usernames, group names, or passwords.
