/**
 * 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!
