Joomla! 1.6 and later comes with a very powerful and somewhat complex ACL system on its own. Admin Tools is designed to make full use of it. In order to access the ACL setup, go to Permissions tab. Each group can be setup with the following privileges:, and click on the button in the toolbar. Then, click on the
Allows access to Component Parameters button. This is a core Joomla! privilege.
Self explanatory. If a user doesn't have this privilege, he won't be able to access the component! This is a core Joomla! privilege.
The user can use the utility features of Admin Tools. The features affected are: cleaning the temporary directory, component access (Control Panel), Emergency Off-Line Mode, fixing and configuring permissions, URL redirections, SEO and link tools.
The user can use the database maintenance features of Admin Tools. The features affected are: session cleanup and table optimization.
The user can use the security features of Admin Tools. The features affected are: access control, administrator password protection, Web Application Firewall setup and associated tools (anti-spam bad words filtering, geo blocking, IP white and black list, log view), .htaccess Maker and Master Password.
We won't go into more details regarding the ACL setup on Joomla! 1.6 and later. If you want more information about how the ACL system works in Joomla! 1.6 and later please consult its documentation or ask on the Joomla! forums.
