Rewrite Attribute when proxy the specific realm

["Rio Yang" <rioyang.tw@gmail.com>]

Hi,

I have tried attr_rewrite function to rewrite attribute value on specific attribute successfully.
But now, I want to rewrite to attribute that proxy to specific realm.
For example, When the AUTH proxy the realm " abc.com".
I wanna to rewrite the attribute "NAS-Identifier" value into new one.
Could somebody know to how configure it?

Thanks.
