Joomla 2.5 Authentication Plugins

The authentication plugins operate when users login to your site or administrator. The Joomla! authentication is in operation by default but you can enable Gmail or LDAP or install a plugin for a different system. An example is included that may be used to create a new authentication plugin.
Default on:

• Joomla Help

Default off:

• Gmail Help (remember to enable curl & ssl libraries)
• LDAP Help
