5 | + * This is a single point of authentication no matter how much | ||
6 | + * authentication modules are in place. Thus it prevents adding | ||
7 | + * more and more authentication modules to the application. | ||
8 | + * This is an auth module itself but this one returns 0 if | ||
9 | + * the authentication has failed otherwise the id of the | ||
10 | + * successfull auth module. Thus we can identify by what method | ||
11 | + * the user has been authenticated. | ||
12 | + * | ||
13 | + * This can't authenticate by its own. It has to be initialized | ||
14 | + * with other auth modules by calling authCreate at least once. | ||
