Update username attribute in NAS

[Anirudh Malhotra]

Hey Everyone,

I have few questions first:
Can User-Name attribute be updated at NAS after authentication is 
completed(post auth)?

Second if yes how?

Third I have tried sending username in update reply but it didn't 
change. I can see the radius sending it though.

[sql]     expand: INSERT INTO radpostauth (username, pass, reply, 
authdate)                           VALUES ( '%{User-Name}', 
'%{%{User-Password}:-%{Chap-Password}}', '%{reply:Packet-Type}', '%S') 
-> INSERT INTO radpostauth                           (username, pass, 
reply, authdate)                           VALUES 
(                           'anirudh', 
'superchor',                           'Access-Accept', '2015-12-09 
10:48:49')
rlm_sql (sql) in sql_postauth: query is INSERT INTO 
radpostauth                           (username, pass, reply, 
authdate)                           VALUES (                           
'anirudh', 'superchor',                           'Access-Accept', 
'2015-12-09 10:48:49')

PS: I am doing this to keep accounting from the sent username. Not the 
current username.

PLEASE HELP!
