Add radius server hostname to tickets

Hi, i'd like to add the radius server's hostname to the tickets, do be able to identify over which server it came in later. For that i've added a new internal freeradius attribute "Server-Hostname" and a block with a gethostname() call to xlat.c. I now update the requests with unlang and add an attribute with %{Server-Hostname} as value. Would you accept a patch for this? Or this there a better way to do this? Regards Stephan Jaeger
