NAME
CGI::Application::Plugin::Authorization::Driver::SimpleGroup - Simple Group based Authorization driver
SYNOPSIS
use base qw(CGI::Application);
use CGI::Application::Plugin::Authorization;
__PACKAGE__->authz->config(
DRIVER => [ 'SimpleGroup' ],
# You are responsible for setting a group param somehow!
GET_USERNAME => sub { my $authz = shift; return $authz->cgiapp->session->param('group') },
);
DESCRIPTION
This driver achieves simplicity by assuming that the "username" method of CGI::Application::Plugin::Authorization will return a group
rather than a username. Thus it can be directly compared with the list of authorized groups passed to authorize
EXAMPLE
use base qw(CGI::Application);
use CGI::Application::Plugin::Authorization;
__PACKAGE__->authz->config(
DRIVER => [ 'SimpleGroup' ],
# You are responsible for setting a group param somehow!
GET_USERNAME => sub {
my $authz = shift;
return $authz->cgiapp->session->param('group');
},
);
sub cgiapp_prerun {
my $self = shift;
# here is an example of how you could set the
# group param that will be tested later
if ($ENV{REMOTE_USER} eq 'mark') {
$self->session->param('group' => 'admin');
}
}
sub my_runmode {
my $self = shift;
# make sure the user has 'admin' privileges
return $self->authz->forbidden unless $self->authz->authorize('admin');
# if we get here the user has 'admin' privileges
}
METHODS
authorize_user
This method is not intended to be used directly. Just follow the SYNOPSIS.
This method accepts a username followed by a list of group names and will return true if the user belongs to at least one of the groups.

NAME
CGI::Application::Plugin::Authorization::Driver::DBI - DBI Authorization driver
SYNOPSIS
use base qw(CGI::Application);
use CGI::Application::Plugin::Authorization;
# Simple task based authentication
__PACKAGE__->authz->config(
DRIVER => [ 'DBI',
TABLES => ['account', 'task'],
JOIN_ON => 'account.id = task.accountid',
USERNAME => 'account.name',
CONSTRAINTS => {
'task.name' => '__PARAM_1__',
}
],
);
if ($self->authz->authorize('editfoo') {
# User is allowed access if it can 'editfoo'
}
DESCRIPTION
This Authorization driver uses the DBI module to allow you to gather authorization information from any database for which there is a DBD
module. You can either provide an active database handle, or provide the parameters necessary to connect to the database.
DBH
The DBI database handle to use. Defaults to "$self->dbh()", which is provided and configured through CGI::Application::Plugin::DBH
When describing the database structure you have two options:
TABLE(S), JOIN_ON, USERNAME and CONSTRAINTS:
Use these values to describe the table structure, and an sql statement will be automatically generated to query the database
SQL:
just provide one SQL parameters that gives a complete sql statement that will be used to query the database
Following is a description of all the available parameters:
TABLE(S)
Provide either a single table name, or an array of table names. You can give the table names aliases which can be referenced in later
columns.
TABLE => 'group',
- or -
TABLES => ['user U', 'group G'],
JOIN_ON
If you have specified multiple tables, then you need to provide an SQL expression that can be used to join those tables.
JOIN_ON => 'user.id = group.userid',
- or -
JOIN_ON => 'U.id = G.userid',
USERNAME
This should be set to the column name that contains the username. This column will be compared against the currently logged in user.
USERNAME => 'name'
- or -
USERNAME => 'U.name'
CONSTRAINTS
Constraints are used to restrict the database query against the options that are passed to the "authorize" method. In the common case, you
will check these parameters against a group permission table, although there is no limit to the number of parameters that can be used.
Each constraint can be set to a static value, or it can be set to '__PARAM_n__' where 'n' is the position of the parameter that is passed
in to the "authorize" method.
CONSTRAINTS => {
'user.active' => 't',
'group.type' => '__PARAM_1__',
'group.name' => '__PARAM_2__',
}
SQL
If you need to perform a complex query that can not be defined by the above syntax, then you can provide your own SQL statment where the
first placeholder is used to fill in the username, and the rest of the placeholders are filled in using the parameters passed to the
authorize method.
SQL => 'SELECT count(*)
FROM account
LEFT JOIN ip ON (account.id = ip.accountid)
LEFT JOIN task ON (account.id = task.accountid)
WHERE account.name = ?
AND (ip.address >> inet ? OR task.name = ?)
',
EXAMPLE
#
# Example table structure (for PostgreSQL):
#
CREATE TABLE account (
id SERIAL NOT NULL PRIMARY KEY,
name VARCHAR(50) NOT NULL
);
CREATE TABLE task (
id SERIAL NOT NULL PRIMARY KEY,
accountid INTEGER NOT NULL REFERENCES account(id),
name VARCHAR(50) NOT NULL
);
CREATE TABLE ip (
id SERIAL NOT NULL PRIMARY KEY,
accountid INTEGER NOT NULL REFERENCES account(id),
address INET NOT NULL
);
INSERT INTO account (name) VALUES ('testuser');
INSERT INTO task (accountid, name) VALUES (1, 'editfoo');
INSERT INTO ip (accountid, address) VALUES (1, '192.168.1.0/24');
# Simple task based authentication
__PACKAGE__->authz->config(
DRIVER => [ 'DBI',
# the handle comes from $self->dbh, via the "DBH" plugin.
TABLES => ['account', 'task'],
JOIN_ON => 'account.id = task.accountid',
USERNAME => 'account.name',
CONSTRAINTS => {
'task.name' => '__PARAM_1__',
'task.active' => 't'
}
],
);
if ($self->authz->authorize('editfoo') {
# User is allowed access if they can 'editfoo'
}
# IP address configuration
__PACKAGE__->authz('byIP')->config(
DRIVER => [ 'DBI',
SQL => 'SELECT count(*)
FROM account JOIN ip ON (account.id = ip.accountid)
WHERE account.name = ?
AND ip.address >> inet ?
',
],
);
if ($self->authz('byIP')->authorize($ENV{REMOTE_ADDR}) {
# User is allowed to connect from this address
}
# both together in one test
# IP address configuration
__PACKAGE__->authz->config(
DRIVER => [ 'DBI',
SQL => 'SELECT count(*)
FROM account
JOIN ip ON (account.id = ip.accountid)
JOIN task ON (account.id = task.accountid)
WHERE account.name = ?
AND task.name = ?
AND ip.address >> inet ?
',
],
);
if ($self->authz->authorize('editfoo', $ENV{REMOTE_ADDR}) {
# User is allowed to connect from this address if they can
# also 'editfoo'
}
METHODS
authorize_user
This method accepts a username followed by a list of parameters and will return true if the configured query returns at least one row based
on the given parameters.
