"plain"
a plug-in authentication module for pajamas.
If, for some insane reason, you don't have access to a JavaScript-capable
browser, use this 'plain' module, otherwise, use 'pj'. You could feasibly
allow users to choose, I guess. :/
The plain module has many of its features of the more secure 'pj' module;
sessions, IP check, time-out, etc., and can be configured in exactly the
same way as, too. The only real difference being that the password is sent
over the wire in *plain* text. JavaScript is not required.
With the pajamas plain module, at least the password travels over the wires
one time only, unlike HTTP basic authentication, which send the password with
*every single request*! Probably that's what your site hosting admin uses,
crazy, huh.
Usage:
Rename this file to plain.php and place alongside other pajamas
modules in the pajamas "modules" folder.
Then simply load pajamas as usual. ie..
include '/path/to/pajamas.php';
$auth = new pajamas();
or
$auth = new pajamas('MyUid'); // optionally pass an id
and then, before you use the module, with your other preferences, set..
$auth->_default_module = 'plain';
If you need to use the plain module in 'simple' mode, set that inside pajamas,
or else call it like this.. $auth = new pajamas('uid-plain');
If you need help, mail me @ corz.org, or if you think a solution to your
issue would be valuable to others, drop a comment on the pajamas page.

Have fun!
;o)
ps.. Like all pajamas modules, the plain module can also be accessed
directly, if required.
