Extend and customize Drupal functionality with contributed modules. If a module doesn't quite do what you want it to do, if you find a bug or have a suggestion, then join forces and help the module maintainer. Or, share your own by starting a new module.

CAPTCHA

Image CAPTCHA example

A CAPTCHA is a challenge-response test most often placed within web forms to determine whether the user is human. The purpose of CAPTCHA is to block form submissions by spambots, which are automated scripts that post spam content everywhere they can. The CAPTCHA module provides this feature to virtually any user facing web form on a Drupal site.

Co-maintainer wanted

We do this our spare time, which is unfortunately almost nonexistent at the moment due to real life obligations. To give the CAPTCHA module the required level of maintenance, an extra co-maintainer would be welcome. If you're interested in helping with this very popular module, please contact me or open an issue in the CAPTCHA module issue tracker.

This module implements the OAuth 1.0 standard for use with Drupal and acts as a support module for other modules that wish to use OAuth.

Downloads

Masquerade

The Masquerade module allows site administrators (or anyone with enough permissions) to switch users and surf the site as that user (no password required). That person can switch back to their own user account at any time.

This is helpful for site developers when trying to determine what a client, logged in as themselves, might see when logged into the site.

Login Destination

Login Destination

The Login Destination module allows you to customize the destination that a user is redirected to after logging in, registering to the site (7.x), using a one-time login link or logging out (7.x). The destination can be an internal page or an external URL. It is possible to specify certain conditions like referring pages or user roles and make the destination depend upon them. You may use PHP snippets to provide custom conditions and destinations. It is also possible to keep users on the currently visited page after logging in or out.

ACL

The ACL module, short for Access Control Lists, is an API for other modules to create lists of users and give them access to nodes. It has no UI of its own and will not do anything by itself; install this module only if some other module tells you to.

We're aware of the following modules using ACL (let us know if you know of others):

Override Node Options

Override Node Options

The Override Node Options module allows permissions to be set to each field within the Authoring information and Publishing options field sets on the node form. It also allows selected field sets to be set as collapsed and / or collapsible.

To install:

  1. Download, unpack and place in sites/all/modules/
  2. Adjust access control in admin/user/permissions
  3. Adjust Fieldset options in admin/settings/override_node_options

Note: Autocomplete "Authored by" field only works if user has "Access user profiles" permission.

Downloads

Password policy

This module provides a way to enforce restrictions on user passwords by defining password policies.

Downloads

view_unpublished

Description:
This module allows you to grant access for specific user roles to view unpublished nodes of a specific type. Access control is quite granular in this regard.

Additionally, using this module does not require any modifications to your existing URL structure.

Downloads

Redirect 403 to User Login

Redirect the HTTP 403 error page to the Drupal /user/login page with an optional message that reads:

"Access denied! You must login to view this page."

Also, the desired page is appended in the url query string so that, once login is successful, the user is taken directly where they were originally trying to go.

Downloads

Menu Admin per Menu

By default, Drupal allows only users with "administrer menu permission" to add, modify or delete menu items.
In case you want for instance to let certain users manage primary links or secondary links but not navigation menu, this module provides this functionality.

Lightweight Directory Access Protocol (LDAP)

Overview

The Lightweight Directory Access Protocol (LDAP) project provides integration with LDAP for authentication, user provisioning, authorization, feeds, and views. It also provides apis and building blocks (query and server configuration storage) for other modules.

Downloads

Nodeaccess

Nodeaccess Grant tab

Nodeaccess is a Drupal access control module which provides view, edit and delete access to nodes. Users with the 'grant node permissions' permission will have a grant tab on node pages which allows them to grant access to that node by user or role. Administrators can set default access controls per content type, and also define which roles are available to grant permissions to on the node grants tab.

The upshot is, this module allows you to do things like 'node 123 can be viewed by authenticated users and edited by admin users and joeuser'. As an added bonus, update and delete permissions are separated, so you can make sure users with edit permissions cannot accidentally delete pages.

7.x version
The previous maintainer (chadcf) had released a dev version of nodeaccess for D7. Over the following months a number of bugs/issues were reported and as of May 7th, 2013, all bug reports in the issue queue have been addressed (where possible) and with that, version 7.x-1.0 has been released as a stable/recommended release for Drupal 7.

Spambot

Spambot protects the user registration form from spammers and spambots by verifying registration attempts against the Stop Forum Spam (www.stopforumspam.com) online database. It also adds some useful features to help deal with spam accounts.

This module works well for sites which require user registration before posting is allowed (which is most forums).

User Import

Import users into Drupal, or update existing users, with data from a CSV file (comma separated file). Provides a wide range of features out of the box, and a comprehensive API to customise imports.

Downloads

Spamicide

The purpose of Spamicide is to prevent spam submission to any form on your Drupal web site. Spamicide adds an input field to each form then hides it with css, when spam bots fill in the field the form is discarded. The field, and matching .css file, are named in such a way as to not let on that it is a spam defeating device, and can be set by admins to almost anything they like(machine readable please). If logging is set, the log will show if and when a particular form has been compromised, and the admin can change the form's field name (and corresponding .css file) to something else.

Downloads

Taxonomy Access Control

Access control for user roles based on taxonomy categories (vocabulary, terms).

Downloads

OAuth Connector

Makes it possible to connect and sign in a Drupal user with accounts on most third party sites with OAuth API:s.

Provides a UI for adding and editing specifications of OAuth API:s that the users should be able to connect to. Also provides exportability of those specifications.

Is an implementation of the Connector module.

Downloads

Secure Login

Secure Login

Secure Login module enables the user login and other forms to be submitted securely via HTTPS, thus preventing passwords and other private user data from being transmitted in clear text. Secure Login module locks down not just the user/login page but also any page containing the user login block (or other forms that you configure to be secured).

Downloads

CustomError

This module allows the site admin to create custom error pages for HTTP status codes 403 (access denied) and 404 (not found), without the need to create nodes for each of them.

Downloads

No request new password

Remove "Request new password" link from block and user page.

This module is very useful for sandbox sites where test users can't change your own password and for third party authentication like LDAP.

Login warnings problem

If you are having problems with login warnings, please take a look at this issue:

CAPTCHA Pack

CAPTCHA Pack examples

The CAPTCHA Pack module contains several CAPTCHA types for use with the CAPTCHA module. The CAPTCHA Pack module is meant to provide lightweight, yet effective alternatives for the traditional image CAPTCHA, which is undesirable in certain situation (e.g. bandwidth restrictions, cpu restrictions, accessibility constraints, etc).

Remember me

Remember me login

Fostering a relationship of trust with your visitors is essential when you aim to collect personal information and provide a service with which they feel secure. With this familiar little feature added to your installation you will portray the message of making every effort to address your users' security concerns and put them at ease. It shows that you stop at nothing to go the extra mile and allow them the peace of mind, to access your site with confidence from anywhere in the world knowing that you have taken every precaution to ensure their identity is safe.

Did you know that the default Drupal behaviour is to remember your session for the extent of 3 weeks and 2 days. This entails that if a user abandons a workstation, closes the browser window, experiences a power failure or any other unforeseen circumstance where they refrain from logging out, that their session will stay active on the server. When, at a later stage, they or anyone else for that matter, returns to your site using the same browser within the session cookie lifetime they will automatically be logged in without being prompted for authentication credentials. Can you imagine the colossal risk this places on users accessing your service from public terminals or shared workstations, with no means to their disposal of securing themselves against this threat.

BOTCHA Spam Prevention

BOTCHA screenshot

BOTCHA is a highly configurable non-CAPTCHA spam protection framework.

In CAPTCHA, user has to prove he/she is human. Unfortunately, spambots learned
to bypass CAPTCHA really well, and real users are frustrated with increasing
complexity and burden of CAPTCHA.

In BOTCHA, we don't abuse our human users - BOTCHA protection is completely
transparent to them and non-intrusive.

BOTCHA lets spambots to prove they are bots, and let real users zip by.

BOTCHA is useful for any form that has to be protected from spambots.

BOTCHA always works as designed - guaranteed! All of BOTCHA recipes are covered by Selenium-tests and we have our own "TestSwarm" to do testing as often as possible: see #1894478: The latest Selenium-tests launches & reports for details.
