eGroupWare Addressbook 1.3+ LDAP support
========================================

The new Addressbook requires only the inetOrgPerson schema.

If you want to use extra attributes availible in the SQL addressbook
like eg. the home-address you need to use some other supported schema:
- evolutionOrgPerson	used by evolution
- mozillaAbPersonAlpha	used by thunderbird & sunbird 1.5+
- mozillaOrgPerson		older mozilla schema (depricated, but mostly compatible to mozillaAbPersonAlpha)

Please note: 
You can or should install the evolutionPerson schema together with ONE
of the mozilla schemas. You can NOT install both mozilla schema!

If the addressbook detects a schema, it fills the extra fields of that schema.

LDAP layout used for the eGroupWare addressbook
-----------------------------------------------

dc=domain,dc=com    base DN of your LDAP server
|
+-o=default         base DN for the addressbook of eGroupWare domain / DB instance "default"
| |                 (specified in Admin >> Addressbook >> Site config)
| |
| +-ou=accounts     base DN for accounts (specified in Setup >> Configuration)
| | +-uid=ralf      entry for user ralf
| | +-uid=lars      entry for user lars
| | +-uid=...       other users
| |
| +-ou=groups       base DN for groups (specified in Setup >> Configuration)
| | +-cn=Default    entry for the group Default
| | +-cn=...        other groups
| |
| +ou=contacts
|   |
|   +-ou=shared     shared addressbooks of the groups
|   | +-cn=default  addressbook of group Default
|   | +-cn=...
|   |
|   +-ou=personal   personal addressbooks of the users
|     +-cn=ralf     addressbook of user ralf
|     +-cn=lars     addressbook of user lars
|     +-cn=...
|
+-o=other           other eGroupWare domain / DB instance
  +-...

The contact base DN must include the accounts and groups base DN, otherwise they will not be 
searched AND the ACL given below does NOT work!
 
The example acl_addressbook.conf allow:
--------------------------------------
- only the user to read, edit or delete in his personal addressbook
- group-members to read, edit or delete in their group addressbook(s)

Please note: 
-----------
- The group ACL requires that the used groups have the groupOfNames objectclass with
  member attributes containing the dn's of all members! The memberUid attribute of
  posixGroup is NOT enough. If you use a distribution other then SuSE, you can NOT
  use both objectclasses together, as both are structural objects. You have to use
  the alternative rfc2307bis.schema instead of the stock nis.schema to do so.
  The README in phpgwapi/doc/ldap describs how to change your ldap accordingly!
- You need to copy our example acl_addressbook.conf into your openldap conf dir.
- You need to change all dc=domain,dc=com with the base DN your LDAP uses!!!
- If you want to use the old mozillaOrgPerson schema, you need to change it here too!
- You need to include "your" acl_addressbook.conf BEFORE the last acl entry (access to *) 
  in your slapd.conf and restart the LDAP server. 
  
This is how the default ACL's in /etc/openldap/slapd.conf of my (SuSE 10.1) looks and 
where I included it:

access to dn.base=""
        by * read

access to dn.base="cn=Subschema"
        by * read

access to attrs=userPassword,userPKCS12
        by self write
        by * auth

access to attrs=shadowLastChange
        by self write
        by * read

include /etc/openldap/acl_addressbook.conf

access to *
        by * read
