NAME

Data::ACL - Perl extension for simple ACL lists

SYNOPSIS

  use Data::ACL;
  use Set::NestedGroups; # You should acquire this module from CPAN

  my $groups = new Set::NestedGroups;
  $groups->add('root', 'wheel');
  $groups->add('wheel', 'staff');
  $groups->add('webmaster', 'staff'); # See Set::NestedGroups documentation

  my $acl = new Data::ACL($groups);
  my $web = $acl->Realm("web");
  $web->Deny('all');
  $web=>Allow('staff');
  $web->Deny('.boss'); # User boss, not group

  &DenyAccess unless $acl->IsAuthorized($user, 'web');

DESCRIPTION

This module implements Deny/Allow series, and requires Set::NestedGroups to define the groups.

Permissions are given per realm. A special realm called 'all' may contain prerequisites for all other realms. If evaluating that realm results in denying access, the specific realm is not evaluated. Otherwise evaluation proceeds to it.
