I am trying to give you more details

The perl module has been enabled in '/etc/raddb/sites-available/default' as below

authenticate {
       
        Auth-Type Perl {
                perl
        }

authorize {
…
        files
        perl
        if (ok || updated) {
            update control {
            Auth-Type := Perl
            }
        }

The custom script perl is invoked since '/etc/raddb/mods-enabled/perl'
perl {
        …
        filename = ${modconfdir}/${.:instance}/radius_proxy.pl
…

I don't use the "users" file for anything else.
As you see the 'files' module was configured before 'perl'. But unfortunately this configuration (and your proposal) seems not suitable:(

  I'm not sure what that means, but OK...

  So you're not using the built-in proxy functionality.  Instead, you're using a Perl module that does the proxying.

  While this can work, I suspect it will have limited performance.

  We've re-engineered the "master" branch in github to support this functionality in a standard way.  It's not ready for an official release yet, but it does work.

  You didn't really describe what you *are* doing, or include any debug output.  So I'll have to guess.  Having *specific* information in your email helps us to give *specific* answers.  In contrast, vague questions result in vague answers.

  The issue is that you're *always* running the Perl script.  If you read the documentation and examples, you will see how to *conditionally* run modules.  Reading the debug output also helps.

  The solution should then be fairly straightforward.  You can edit the "authorize" section:

authorize {
	...
	files
	if (control:Auth-Type == "Accept") {
		perl
	}
	...
}

  i.e. run the "files" module. If it doesn't set "Auth-Type Accept", then run the perl module.

  This might not work if you're already using the "users" file to do other things.  But since you're not really describing what you're doing, I can't really help much more than that.
