/**
 * LDAP Backend for accounts
 *
 * 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 AND
 * matches the LDAP search filter specified in setup >> configuration.
 * 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!
