=head1 DESCRIPTION
|
|
|
|
This plugin implements a very simple authentication plugin using a flat password
|
|
file containing username and password separated by colons.
|
|
|
|
Note that this plugin enforces the use of a full email address (including
|
|
@domain) as the username. There's no particular reason for this so feel free
|
|
to modify the code to suit your setup.
|
|
|
|
The password is stored on disk unencrypted, however authentication uses a HMAC
|
|
algorithm so no password is transfered in the clear.
