An RBAC authorization is a discrete right that can be granted to a role or a user. Authorizations are checked by RBAC-compliant applications before a user gets access to the application or specific operations within the application. This check replaces the tests in conventional UNIX applications for UID=0.
An authorization has a name that is used internally and in files. For example, solaris.print.admin is the name of an authorization. An authorization has a short description, which appears in the graphical user interfaces (GUIs). For example, Administer Printer is the description of the solaris.print.admin authorization.
By convention, authorization names consist of the reverse order of the Internet name of the supplier, the subject area, any subareas, and the function. The parts of the authorization name are separated by dots. An example would be com.xyzcorp.device.access. Exceptions to this convention are the authorizations from Sun Microsystems, Inc., which use the prefix solaris instead of an Internet name. The naming convention enables administrators to apply authorizations in a hierarchical fashion. A wildcard (*) can represent any strings to the right of a dot.
As an example of how authorizations are used, consider the following: A user in the Network Link Security role would be limited to the solaris.network.link.security authorization, while the Network Security role has the Network Link Security rights profile as a supplementary profile, plus the solaris.network.* and solaris.smf.manage.ssh authorizations.
An authorization that ends with the suffix grant enables a user or a role to delegate to other users any assigned authorizations that begin with the same prefix.
For example, a role with the authorizations solaris.admin.usermgr.grant and solaris.admin.usermgr.read can delegate the solaris.admin.usermgr.read authorization to another user. A role with the solaris.admin.usermgr.grant and solaris.admin.usermgr.* authorizations can delegate any of the authorizations with the solaris.admin.usermgr prefix to other users.
The solaris auth.delegate authorization enables a user or a role to delegate to other users any authorizations that these users or roles are assigned.
For example, a role with the solaris auth.delegate and solaris.network.wifi.wep authorizations can delegate the solaris.network.wifi.wep authorization to another user or role. Similarly, a role with the solaris auth.delegate and solaris.network.wifi.wep authorizations can delegate the solaris.network.wifi.wep authorization to another user or role.
