26 /* This passdb module retrieves full passdb information for local users and
27 * groups from a wbclient compatible daemon.
29 * The purpose of this module is to defer all SAM authorization information
30 * storage and retrieval to a wbc compatible daemon.
32 * This passdb backend is most useful when used in conjunction with auth_wbc.
34 * A few current limitations of this module are:
35 * - read only interface
