Restrict access to pages.

Download ZIP file and copy it into your system/extensions folder. Learn more about extensions.

Add a Restrict setting at the top of a page to protect it and its descendant pages (top pages are considered children of the home page). The value of the setting is a comma separated list of users and groups that may access the page with their credentials.

This extension relies on the HTTP basic authentication. For sensitive data use it only over an encrypted connection (https://). For a simpler alternative there is the Private extension.

Usernames, passwords and groups are defined in a file system/extensions/restrict.ini, each user for line, with the following syntax:

username:password:@group1,@group2...

You can specify for each username zero or more groups it belongs to. All usernames belong moreover to an implicit group @all.

Page with restricted access:

---
Title: Reserved page
Restrict: john, @admin, @commitee
---

This page is reserved to John, administrators and members of the Commitee.

Usernames, passwords and groups in restrict.ini:

john:a2S%iZhK
mary:cAaRWC8&:@commitee,@admin
ben:5DgZAC&R:@member
lucy:ZWKD(8Jy:@admin,@member
antony:79wB5w@Z:@commitee
mark:9F5)F57e:@member

Passwords are stored in cleartext. Do not use them for any other purpose and transmit them securely to users.

The following setting can be configured in file system/extensions/yellow-system.ini:

RestrictUserFile = filename for users, passwords and groups

For the restricted pages to show the username and a tip for "logging out", add the following line to the file system/layouts/footer.html:

<?php echo $this->yellow->page->getExtraHtml("logout"); ?>

For this extension to work with the Apache webserver, sometimes it is necessary to add to the file .htaccess the following line:

SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

or the following lines:

RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]

Other solutions may be needed.
