Once you log into the backend of Joomla, the administrator panel, the control panel pops up.
One of the options is Global Configuration, and it shows up with a wrench and a screwdriver, indicating tools.
Global Configuration can also be reached by selecting Global Configuration underneath the Permissions menu item.
Four tabs exist in Global Configuration, which are Site, System, Server, and Permissions.
Each of the four tabs has many fields and options.
Some of the settings are obvious, even to the novice.
Others might as well be written in a foreign language.
What do the settings mean? What are they for? What should you set the values to? This article covers the fields and options in the Permissions tab, which is used to set up what each group is allowed to do.
Before talking about the different groups, there are a few vocabulary words to know.
Inherited: Inherited means pretty much what it sounds like.
If Grandpa has red hair and Dad has red hair and Son has red hair, then Dad and Son probably inherited red hair from Grandpa.
Denied: This group cannot do this.
Even if the parent group can, this group cannot.
Allowed: This group can do this.
If the parent group is Denied, however, this group will also be denied.
The different groups Public: This group is the parent of all others.
It's the great, great, great, grandpa of the groups.
By default, all values are set to "Not Set.
" "Not Set" means "Denied," but it is different from the other denied values, because children can overwrite the value.
The public group is anyone that access your site.
They don't have to log in to be public.
Everyone is public unless they log in.
Manager: By default, a member of this group can do most things in the Joomla front end and back end.
They can't access components, global permissions, or component options.
To become a manager, a user with higher permissions must set a user to "Manager" in the Joomla back end.
Administrator: Administrators, by default, are just like managers except they can access components and component options.
To become an Administrator, a user with higher permissions must set a user to "Administrator" in the Joomla back end.
Registered: Registered users are like public users, but they can access content that has been marked registered users.
Author: Besides the values of Registered, authors can also create and edit articles.
Authors only have front end permissions to the site.
They cannot access the Joomla back end (DomainName.
com/administrator).
To become an Author, a user with higher permissions must set a user to "Author" in the Joomla back end.
Editor: Besides the values of an Author, editors can edit other people's articles.
