82 The main function of this module is to provide
83 authentification. However the get_template_and_user function has
84 been provided so that a users login information is passed along
85 automatically. This gets loaded into the template.

105 to C<&checkauth> (in this module) to perform authentification.
106 See C<&checkauth> for an explanation of these parameters.

334 Verifies that the user is authorized to run this script. If
335 the user is authorized, a (userid, cookie, session-id, flags)
336 quadruple is returned. If the user is not authorized but does
337 not have the required privilege (see $flagsrequired below), it
338 displays an error page and exits. Otherwise, it displays the
339 login page and exits.
341 Note that C<&checkauth> will return if and only if the user
342 is authorized, so it should be called early on, before any
343 unfinished operations (e.g., if you've opened a file, then
344 C<&checkauth> won't close it for you).
346 C<$query> is the CGI object for the script calling C<&checkauth>.
348 The C<$noauth> argument is optional. If it is set, then no
349 authorization is required for the script.
351 C<&checkauth> fetches user and session information from C<$query> and
352 ensures that the user is authorized to run scripts that require
355 The C<$flagsrequired> argument specifies the required privileges
356 the user must have if the username and password are correct.
357 It should be specified as a reference-to-hash; keys in the hash
358 should be the "flags" for the user, as specified in the Members
359 intranet module. Any key specified must correspond to a "flag"
360 in the userflags table. E.g., { circulate => 1 } would specify
361 that the user must have the "circulate" privilege in order to
362 proceed. To make sure that access control is correct, the
363 C<$flagsrequired> parameter must be specified correctly.
365 The C<$type> argument specifies whether the template should be
366 retrieved from the opac or intranet directory tree. "opac" is
367 assumed if it is not specified; however, if C<$type> is specified,
368 "intranet" is assumed if it is not "opac".
370 If C<$query> does not have a valid session ID associated with it
371 (i.e., the user has not logged in) or if the session has expired,
372 C<&checkauth> presents the user with a login page (from the point of
373 view of the original script, C<&checkauth> does not return). Once the
374 user has authenticated, C<&checkauth> restarts the original script
375 (this time, C<&checkauth> returns).
377 The login page is provided using a HTML::Template, which is set in the
378 systempreferences table or at the top of this file. The variable C<$type>
379 selects which template to use, either the opac or the intranet
380 authentification template.
382 C<&checkauth> returns a user ID, a cookie, and a session ID. The
383 cookie should be sent back to the browser; it verifies that the user
