Privileges
A privilege combines permissions into a logical task. A permission provides
the rights to do a single task. There are some IPA operations that require
multiple permissions to succeed. A privilege is where permissions are
combined in order to perform a specific task.
For example, adding a user requires the following permissions:
* Creating a new user entry
* Resetting a user password
* Adding the new user to the default IPA users group
Combining these three low-level tasks into a higher level task in the
form of a privilege named "Add User" makes it easier to manage Roles.
A privilege may not contain other privileges.
See role and permission for additional information.
