freeradius accounting of cdr and quotes for string attributes

[Kelly Roestel]

My question is this,

I need to write CDR information out using the linelog module in csv 
format.  The requirement is that all string attributes need to be 
enclosed in double quotes.  How does one go about doing this?

If you look at the detailed format, these string attributes are 
enclosed.  But there seems to be no option in linelog module.

I am using freeradius v2.1.10.

Thanks for any help
