 Products.LDAPUserFolder
=========================

.. contents::

This product is a replacement for a Zope user folder. It does not store its 
own user objects but builds them on the fly after authenticating a user against 
the LDAP database.


Bug tracker
===========
Please post questions, bug reports or feature requests to the bug tracker
at https://bugs.launchpad.net/ldapuserfolder


Debugging problems
==================
All log messages are sent to the standard Zope event log 'event.log'. In 
order to see more verbose logging output you need to increase the log level 
in your Zope instance's zope.conf. See the 'eventlog' directive. Setting 
the 'level' key to 'debug' will maximize log output and may help pinpoint 
problems during setup and testing.


Why does the LDAPUserFolder not show all my LDAP groups?
========================================================
According to feedback received from people who use Netscape directory 
products the way a new group is instantiated allows empty groups to exist 
in the system. However, according to the canonical definition for group 
records groups must always have a group member attribute.
The LDAPUserFolder looks up group records by looking for group member 
entries. If a group record has no members then it will be skipped. As said 
above, this only seems to affect Netscape directory servers.
To work around this (Netscape) phenomenon add one or more members to the 
group in question using the tools that came with the directory server. It 
should appear in the LDAPUserFolder after that.


Why use LDAP to store user records?
===================================
LDAP as a source of Zope user records is an excellent choice in many cases, 
like...

- You already have an existing LDAP setup that might store company employee 
  data and you do not want to duplicate any data into a Zope user folder
- You want to make the same user database available to other applications 
  like mail, address book clients, operating system authenticators 
  (PAM-LDAP) or other network services that allow authentication against
  LDAP
- You have several Zope installations that need to share user records or a 
  ZEO setup
- You want to be able to store more than just user name and password in your 
  Zope user folder
- You want to manipulate user data outside of Zope

... the list continues.


The LDAP Schema
===============
Your LDAP server should contain records that can be used as user 
records. Any object types like person, organizationalPerson, 
or inetOrgPerson and any derivatives thereof should work. Records
of type posixAccount should work correctly as well.
The LDAPUserFolder expects your user records to have at least the 
following attributes, most of which are required for the 
abovementioned object classes, anyway:

- an attribute to hold the user ID (like cn, uid, etc)
- userPassword (the password field)
- objectClass
- whatever attribute you choose as the username attribute
- typcial person-related attributes like sn (last name), 
  givenName (first name), uid or mail (email address) will make 
  working with the LDAPUserFolder nicer

Zope users have certain roles associated with them, these roles
determine what permissions the user have. For the LDAPUserFolder,
role information can be expressed through membership in group
records in LDAP.

Group records can be of any object type that accepts multiple 
attributes of type "uniqueMember" or "member" and that has a 
"cn" attribute. One such type is "groupOfUniqueNames". The cn 
describes the group / role name while the member attributes point 
back to all those user records that are part of this group. Only
those group-style records that use full DNs for its members
are supported, which excludes classes like posixGroup.

For examples of valid group- and user-records for LDAP please
see the file SAMPLE_RECORDS.txt in this distribution. It has 
samples for a user- and a group record in LDIF format.

It is outside of the scope of this documentation to describe the 
different object classes and attributes in detail,
