Variable passing between autz,acct stages

[flamur2]

Hi,
Is it possible to pass a variable from authorization modules to 
accounting modules, (by using Tmp-String* attributes) ?

My radius config is like this

authorization is done via files module, where Tmp-String-0 is set:
"u1"    Crypt-Password := "$1$7ZSTJ83K$IUVxdrj8TxA2nftXzx7AH.", 
Tmp-String-0 := "pppoe25", Expiration := "10 Jan 2010"

accounting is done via sql.


In sql module (used only for accounting) I need to reference 
Tmp-String-0, is this possible ?

Thanks,
Flamur
