Hi

I use this line many years in the preacct_users file ( freeradius 2.1.X )

DEFAULT Called-Station-Id == "orangewap"

        Called-Station-Id := "%{Called-Station-Id}.%{3GPP-SGSN-Address}"

It`s not work in freeradius-2.2.0, i got error message

[files] preproxy_users: Matched entry DEFAULT at line 39

[files] WARNING: Unknown module "3GPP-SGSN-Address" in string expansion "%"

++[files] returns ok
