Maurits van Rees: 3 authentication add-ons

Filed Under:

Lightning talk by Maurits van Rees at the Plone Conference 2019 in Ferrara.

Three PAS plugins:

  • collective.denyroles
  • pas.plugins.headers
  • collective.contentgroups

collective.denyroles

Deny access to roles like Manager and Editor

  • Use case: Manager only logs in to edit-domain, not live site.
  • By default deny access to Manager, Editor, etc.
  • env DENY_ROLES=0 to disable
  • or Apache/nginx header X_DONT_CHECK_ROLES
  • Actually not a plugin, but a patch.

pas.plugins.headers

PAS plugin for authentication based on request headers.

  • Use case: Apache/nginx adds SAML headers to requests.

  • Configuration in ZMI or profiles/default/pas.plugins.headers.json:

    {
        "userid_header": "uid",
        "required_headers": ["uid"],
        "roles_header": "roles",
        "allowed_roles": ["student", "teacher"],
        "deny_unauthorized": true,
        "redirect_url": "https://maurits.vanrees.org",
        "memberdata_to_header": [
            "fullname|HEADER_firstname HEADER_lastname"
        ]
    }

collective.contentgroups

Plone PAS plugin for content as groups.

  • Use case: create content item that works as a group.
  • dexterity behavior
  • No Products.membrane, no Products.remember, no dexterity.membrane.
  • No separate membrane_catalog.
  • Only groups, not users.
  • No multiple inheritance, just AccessControl.users.BasicUser.
