IP Login

Automatically log in via IP address, range or wildcard.

This module allows users to login automatically via their IP (v4) address ranges or wildcards instead of having to enter a username and password - plus many other features.

News

January 2012

• The 6.x-1.x branch is now deprecated. When you upgrade to 6.x-2.x (and you should, it's much better!) the IP field you added to users via core the Profile module will be auto-imported into the new ip_login_users table, so if you're not using Profile module for anything else it can safely be disabled.
• Jim Kirkpatrick: New 'Log in by IP' block with a simple link, plus bug fixes.
• JohnV: Mildly refactored for better clarity and simpler code, plus several bugs fixed.
• Coming soon: Once the full 2.x release is out, work will begin on IPv6 and subnet matching support. Please see the issue queue if you have any ideas or want to help with these features.

Features

• Integration with User Login page and block, with customisable text and labels
• 'Log in by IP' block with simple auto-login link for those who don't want to use the modified User Login block.
• Users with permission can log out and and back into another account.
• Can be set to auto-login (or not) only on certain pages, or when custom PHP returns TRUE.
• Optional destination address can be set when logged in by IP.
• Lists IP-enabled users on the admin page at 'Site configuration' -> 'IP Login'.
• IP address matching works on:
  • Normal single IPs, comma separated: 123.4.5.6 or 123.4.5.6, 234.5.6.7
  • IP ranges: 123.4.5.6-10 or 123.4-111.5.6
  • Wildcards: 123.4.5.* or 123.*.*.*
  • Any combination: 127.0.0.1, 123.4.5-66.*, 234.4-5.6-77.*
  • Coming soon: IPv6 and Subnet matching via CIDR notation.
• Will work with external caches like Varnish when IP Login is set to auto-login only on specific paths.

How it works

When a user visits any Drupal page (or admin-chosen page), IP Login will:

1. Check if the user is not logged in and that IP login hasn't run yet for this session.
2. If so, it compare the IP address (using Drupal's ip_address() function) to IP ranges stored in its own private table in the database.
3. If a match is found, IP Login logs the user in programmatically as the account matching the IP address.
4. If a matching IP is not found, the user can log in via normal Drupal accounts if they choose to.
5. If the user has permission to log out, they can and will be given the option to login back in normally as another user. Users without this permission are auto-logged back in IP Login. This way you can force an IP address to stay associated and logged into an account.
