Download/Install IDENTD
IDENTD is the small software program that must be installed on each user’s client computer if multiple filters
are to be used in ComSifter using the Identd authentication method
The program may be installed and executed locally on each client computer, or may be installed on a Domain
Controller and pushed to client computers on user login. If a Domain Controller is available, this is considered
a best practice as the program is installed once and is installed from a secure source.
As part of configuring ComSifter, usernames must be entered in the ComSifter Username Database, and a
filter level associated with the username. During normal operation, when a user computer requests a website,
the ComSifter will query the IP of the requesting computer and ask for its IDENTD. The IDENTD program will
respond with the username of the user currently logged into the computer.
ComSifter then matches the username with the filter associated in the ComSifter Username Database and
applies the filter settings appropriate for that filter. By using IDENTD, multiple users may log into and out of a
computer during the day and they will be filtered based on their username, not the computer.
If a user computer that does not have IDENTD installed is queried, and thus does not respond, ComSifter will
automatically assign that computer user the username
nousername
. By default,
nousername
is automatically
routed to the non-IDENTD filter (Filter 1 non-IDENTD).
