we are trying to pursue this approach.  I am trying to figure out how to
get multiple values out of the database.

I have got this:

update control {
	DL-Device-Vendor := "%{sql:SELECT devicevendor FROM userinfo   \
            WHERE username='%{request:User-Name}' }"

(NB no line break in reality).

working inside a post-auth block inside /etc/freeradius/sites-enabled
/default.  (In that I run freeradius -X and see the query running
in the debug output).

Now what I want is to run a longer and more complicated query and set up
multiple attributes.  (Our current post-auth script pulls some 13 items
out of the database).

The only thing I have found on this so far is this page on github:

So I tried this :

map sql "SELECT devicevendor FROM userinfo WHERE \
           username='{request:User-Name}'" {
                 XL-Device-Vendor := 'devicevendor'

and got this error:
  Expecting section start brace '{' after "map sql"
(Also tried with 'mysql' rather than 'sql' - which
should it be, anyway?)

How do I go about this?
