<section><title>Access control in NNTPd</title>
|
|
<para>
|
|
The original NNTPd had host-based authentication which allowed clients
|
|
connecting from a particular IP address to read only certain newsgroups.
|
|
This was very clearly inadequate for enterprise deployment on an
|
|
Intranet, where each desktop computer has a different IP address, often
|
|
DHCP-assigned, and the mapping between person and desktop is not static.
|

|
|
What was needed was a user-based authentication, where a username and
|
|
password could be used to authenticate the user. Even this was provided
|
|
as an extension to NNTPd, but more was needed. The corporate IS manager
|
|
needs to ensure that certain Usenet discussion groups remain visible only
|
|
to certain people. This authorisation layer was not available in NNTPd.
|
|
Once authenticated, all users could read all newsgroups.

|
We have extended the user-based authentication facility in NNTPd in some
|
|
(we hope!) useful ways, and we have added an entire authorisation layer
|
|
which lets the administrator specify which newsgroups each user can
|
|
read. With this infrastructure, we feel NNTPd is fit for enterprise
|
|
deployment and can be used to handle corporate document repositories,
|
|
messages, and discussion archives. Details are given below.
