I've used an "if" statement testing "%{config:modules.sql.server}", which I expected to give me the value "NPS" if I had set the value and null otherwise. That way I thought I could just comment out the "$INCLUDE mssql.conf" in radius.conf, and the "sql" in the "instantiate" section (we are only using SQL in "xlat" expressions) and avoid the "xlat" expressions being evaluated. However, it looks like whether I include "mssql.conf" or not, that expression always evaluates to "localhost". I'm baffled. Should this work? I got this expression format from https://github.com/FreeRADIUS/www.freeradius.org/blob/master/radiusd/doc/variables.txt. 

Yes that should work. Weird.

Could you see if 

if ("${modules.sql.server}" == 'NPS') {

}

Is any better?
