Summary

Let's list some key points to remember on modules:

• Modules help to extend the functionality of FreeRADIUS.
• One module can run different instances through the use of named sections.
• Modules are configured through text files under the modules sub-directory in the FreeRADIUS configuration directory.
• The order of modules inside a section is very important.
• A module has return codes that influence the flow of a request.
• We can use unlang to test for a specific return code from a module.
• Some modules may be missing because they are packed separately and have to be installed separately before they can be used.
