<?php
/**
 * New user identity
 *
 * Populates a new user's default identity from LDAP on their first visit.
 *
 * This plugin requires that a working public_ldap directory be configured.
 *
 * @version 1.05
 * @author Kris Steinhoff
 *
 * Example configuration:
 *
 *  // The id of the address book to use to automatically set a new
 *  // user's full name in their new identity. (This should be an
 *  // string, which refers to the $rcmail_config['ldap_public'] array.)
 *  $rcmail_config['new_user_identity_addressbook'] = 'People';
 *
 *  // When automatically setting a new users's full name in their
 *  // new identity, match the user's login name against this field.
 *  $rcmail_config['new_user_identity_match'] = 'uid';
 *
 *  // Use this field (from fieldmap configuration) to fill alias col of
 *  // the new user record.
 *  $rcmail_config['new_user_identity_alias'] = 'alias';
