When using DOUBLE_QUOTED_STRING, passwords with '\"' may not work

[g4-lisz at tonarchiv.ch]

I think what he means is:

The actual password (unescaped) is pass\\"word at 2022. In the Shell you 
would need five(!) backslashes. In Freeradius only three (I didn't test 
this though).

echo "pass\\\\\"word at 2022"
pass\\"word at 2022

Cheers
