attr_rewrite molude - creating new parameter from the existing one

[tzieleniewski]

Hi!

Is it possible to implement such functionality with the usage of attr_rewrite module that whenever a packet arives to freeradius module will check if particular parameter exists in a request and if it doesn't, it will try to create it from other set of packet parameters?  Maybe it can be done in other way not through the attr_rewrite module.

Thanks in advance.
