mod_password_policy: Support for additional policies provided by other modules
E.g. check a password contains an uppercase character:
module:provides("password-policy", {
name = "contains_uppercase";
check_password = function (password, policy)
return (policy ~= true) or (not not password:match("%u"));
end;
})
Config:
password_policy = {
contains_uppercase = true;
}
local io_open = io.open;
local dm = require "core.storagemanager".olddm;
-- Append a blob of data to a file
function dm.append_raw(username, host, datastore, ext, data)
if type(data) ~= "string" then return; end
local filename = dm.getpath(username, host, datastore, ext, true);
local ok;
local f, msg = io_open(filename, "r+");
if not f then
-- File did probably not exist, let's create it
f, msg = io_open(filename, "w");
if not f then
return nil, msg, "open";
end
end
local pos = f:seek("end");
ok, msg = f:write(data);
if not ok then
f:close();
return ok, msg, "write";
end
ok, msg = f:close();
if not ok then
return ok, msg;
end
return true, pos;
end
