egroupware/addressbook/inc/class.socontacts.inc.php
Ralf Becker 9f59a77b85 moved contact-data (firstname, lastname and email) from the account-table to the contact table:
- all (sql) accounts have now allways a contact associated with them (account_id is added as new column to the contacts table)
- contacts queries are simplefied a lot now, as no more join with the accouns-table, union and case when statesments are necessary
- lot of the special handling for accounts in the contacts class is no longer needed
- new contact-repository mode "sql-ldap" which additional writes all changes to the ldap repository, to allow to use it read-only from eg. thunderbird and still have the full sql speed and features within eGW (not yet fully working!)
==> requites update of API and addressbook to work (setup!)

/**
* General storage object of the adressbook
*
* The contact storage has 3 operation modi (contact_repository):
* - sql: contacts are stored in the SQL table egw_addressbook & egw_addressbook_extra (custom fields)
* - ldap: contacts are stored in LDAP (accounts have to be stored in LDAP too!!!).
* Custom fields are not availible in that case!
* - sql-ldap: contacts are read and searched in SQL, but saved to both SQL and LDAP.
* Other clients (Thunderbird, ...) can use LDAP readonly. The get maintained via eGroupWare only.
*
* The accounts can be stored in SQL or LDAP too (account_repository):
* If the account-repository is different from the contacts-repository, the filter all (no owner set)
* will only search the accounts and NOT the contacts! Only the filter accounts (owner=0) shows accounts.
*
* If sql-ldap is used as contact-storage (LDAP is managed from eGroupWare) the filter all, searches
* the accounts in the SQL contacts-table too. Change in made in LDAP, are not detected in that case!
