This cloud wiki setting specifies whether the server should require that any client attempting to edit a node log in, and how it should authenticate those users.
Settings currently recognized by the Cloud Wiki 1.0 server:
| Value | Module | Description |
| none | No Authentication Module | Do not require authentication. This emulates a traditional wiki, permits anyone to make modifications, and is the default configuration of a Cloud Wiki server, as of 1.0. |
| cloud | Cloud Authentication Module | Uses a simple table of user names and passwords to authenticate users. This module has become deprecated in favor of the MD5 Authentication Module. |
| md5 | MD5 Authentication Module | Slightly stronger than the Cloud Authentication Module, this module stores the passwords as MD5 hashes. |
| kabuki | Kabuki Authentication Module | Ties in to the Kabuki user database specified by the auth-db-path setting for authentication. |
| pun | PunBB Authentication Module | Ties in to a PunBB forum using sqlite2. |
You should reboot the server after changing this setting.
Cloud Bug: Altering the Site-Auth on a living server can require purging the user table, especially if moving between Cloud Authentication Module and MD5 Authentication Module. To fix this, you will have to use the sqlite utility to enter the following command:
DELETE FROM CloudAuth;
This will flush your authorization table, allowing you to enter your users from scratch.
