Request Authenticator value made available to a Perl module

[Brandon Miller]

Hi Everyone,

I am working on a Perl module that requires access to the Request
Authenticator value for each Access-Request.

I combed through the docs and found the Request-Authenticator Runtime
variable (https://wiki.freeradius.org/config/run_time_variables).  I
tried to dynamically assign this variable (%V) to a Radius-Request
variable in my site definition file, but the server won't start with
error:

/etc/raddb/sites-enabled/myPerlSite[17]: Failed parsing expanded string:
/etc/raddb/sites-enabled/myPerlSite[17]: %V
/etc/raddb/sites-enabled/myPerlSite[17]:  ^ Invalid variable expansion

It seems this variable has been deprecated in v3.  Is there any way to
get at this variable in another way?   I am running v3.0.13.

Thanks in advance,
Brandon
