/**
|
|
* API - accounts LDAP backend
|
|
*
|
|
* The LDAP backend of the accounts class now stores accounts, groups and the memberships completly in LDAP.
|
|
* It does NO longer use the ACL class/table for group membership information.
|
|
* Nor does it use the phpgwAcounts schema (part of that information is stored via shadowAccount now).
|
|
*
|
|
* A user is recogniced by eGW, if he's in the user_context tree AND has the posixAccount object class.
|
|
* A group is recogniced by eGW, if it's in the group_context tree AND has the posixGroup object class.
|
|
* The group members are stored as memberuid's.
|
|
*
|
|
* The (positive) group-id's (gidnumber) of LDAP groups are mapped in this class to negative numeric
|
|
* account_id's to not conflict with the user-id's, as both share in eGW internaly the same numberspace!
|
|
*
|
|
* @link http://www.egroupware.org
|
|
* @author Ralf Becker <RalfBecker-AT-outdoor-training.de> complete rewrite in 6/2006
|
|
*
|
|
* This class replaces the former accounts_ldap class written by
|
|
* Joseph Engo <jengo@phpgroupware.org>, Lars Kneschke <lkneschke@phpgw.de>,
|
|
* Miles Lott <milos@groupwhere.org> and Bettina Gille <ceb@phpgroupware.org>.
