21 method => "init_authenticate",
22 api_name => "open-ils.auth.authenticate.init",
23 argc => 1, #(username)
25 Generates a random seed and returns it. The client
26 must then perform md5_hex( \$seed . \$password ) and use that
27 as the passwordhash to open-ils.auth.authenticate.complete
31 __PACKAGE__->register_method(
32 method => "complete_authenticate",
33 api_name => "open-ils.auth.authenticate.complete",
34 argc => 2, #( barcode, passwdhash )
36 Client provides the username and passwordhash (see
37 open-ils.auth.authenticate.init). If their password hash is
38 correct for the given username, a session id is returned,
39 if not, "0" is returned
43 __PACKAGE__->register_method(
44 method => "retrieve_session",
45 api_name => "open-ils.auth.session.retrieve",
46 argc => 1, #( sessionid )
48 Pass in a sessionid and this returns the username associated with it
52 __PACKAGE__->register_method(
53 method => "delete_session",
54 api_name => "open-ils.auth.session.delete",
55 argc => 1, #( sessionid )
57 Pass in a sessionid and this delete it from the cache
