LDAP authentication

Goal

Authenticat user against LDAP directories

It will bind with the user's login/pasword and query attributs ("mail" for instance) in a pool of directory servers

The first OK wins.

If there's connection error, the server will be disabled and won't be checked again

Usage

In the [security] section, set

LDAP_AUTH = true

then for each LDAP source, set

[LdapSource-someuniquename] name=canonicalName host=hostname-or-ip port=3268 # or regular LDAP port

the following settings depend highly how you've configured your AD

basedn=dc=ACME,dc=COM MSADSAFORMAT=%s@ACME.COM filter=(&(objectClass=user)(sAMAccountName=%s))

Limitation

Only tested on an MS 2008R2 DC, using global catalog (TCP/3268)

This MSAD is a mess.

The way how one checks the directory (CN, DN etc...) may be highly depending local custom configuration

Todo

• Define a timeout per server
• Check servers marked as "Disabled" when they'll come back online
• Find a more flexible way to define filter/MSADSAFORMAT/Attributes etc... maybe text/template ?
• Check OpenLDAP server
• SSL support ?
