Local User with multiple passwords (or RegEX passwords) possible?

[Equin Nix]

Hi Phil,

thanks a lot for the fast answer! Unfortunatelly your radius-skills seem to
be far far from mine, but I think I get the point.

I tried to add the following to *sites-enabled/default* (int authorize
section) (Its not a full copy of your text, I wanted to start step by step):

[...]
        #
        #  Read the 'users' file
        files {
                # compare them
                if (User-Password != control:Cleartext-Password) {
                        reject
                }


                # probably need to set Auth-Type := Accept here
                update control {
                        Auth-Type := Accept
                }
        }
[...]

and freeradius won't start (even if I remove the update control section).
This is the error:
[...]
/etc/freeradius/sites-enabled/default[154]: Subsection of module instance
call not allowed
/etc/freeradius/sites-enabled/default[62]: Errors parsing authorize section.

Any idea what might cause the trouble? Line 154 is the "if
(User-Password...." line.

BTW: It is not possible with RegEx?

Best regards from Germany
