/**
|
|
* API - accounts SQL backend
|
|
*
|
|
* The SQL backend stores the group memberships via the ACL class (location 'phpgw_group')
|
|
*
|
|
* The (positive) account_id's of groups are mapped in this class to negative numeric
|
|
* account_id's, to conform wit the way we handle groups in LDAP!
|
|
*
|
|
* @link http://www.egroupware.org
|
|
* @author Ralf Becker <RalfBecker-AT-outdoor-training.de> complete rewrite in 6/2006 and
|
|
* earlier to use the new DB functions
|
|
*
|
|
* This class replaces the former accounts_sql class written by
|
|
* Joseph Engo <jengo@phpgroupware.org>, Dan Kuykendall <seek3r@phpgroupware.org>
|
|
* and Bettina Gille <ceb@phpgroupware.org>.
