Overview

membrane is a set of PluggableAuthService (PAS) plug-ins that allow for the user-related behaviour and data (authentication, properties, roles, groups, etc.) to be obtained from content within a Plone site. It does not actually provide a full member implementation, it is intended to be a set of tools from which a full implementation can be constructed. It is meant to be flexible and pluggable, and easy to adapt to different deployment scenarios. It is not meant to be configured through-the-web-only, but to be adapted by filesystem code.

membrane tries to take a step backwards and re-think some of the Plone membership-handling. We have tried to make it as simple as possible, so that grasping and extending it is simple. Hopefully, simplicity should also make it easier to make sure it is secure.

For announcement, help, or to keep up with development discussions, see the poorly named "remember" list:

Vision

membrane is a product to enable users as content in Plone sites, in collaboration with PlonePAS. The name gives you an idea of the intended complexity and amount of code.

membrane won't be the only member handling product in your site, instead it should enable us to easily plug in products that enable default Plone member policy, or more exotic setups in corporate intranets. This means that to get the default Plone behaviour you will need something else in addition to membrane.

Requirements

  • Plone 3.3 or better. Currently tested primarily on Plone 4.2. Works on Plone 4.3 (beta) as well.

WARNING!!

Currently, a catalog is used to index the interfaces implemented by the objects in the portal. However, interfaces are specified programmatically, either via Python code or ZCML. Any time Zope is restarted, interfaces may have changed, and, if they have, the catalog will have become out of date. Work is under way on a more robust interface lookup solution, but for now if you change the interfaces implemented on any membrane related type or object, you may need to explicitly reindex the 'object_implements' interface on the membrane_tool.
Something went wrong with that request. Please try again.
