(RADIATOR) Possible problem in Addtoreplyifnotexist

[Brian Morris]

Happy New Year everyone

During the quiet time between Christmas and New Year we decided to update Radiator.  We updated to v3.11 (from 3.1 ouch) and are now experiencing a problem with the addtoreplyifnotexist parameter.

The symptoms are that the parameter 'Idle-Timeout' is added to the reply no matter whether it has already been set or not.  Causing it to be allocated twice.

Here is the snippet of our radius config...

<Handler Realm=xxx.xxx.xx>
 RewriteUsername s/\s+//g
 RewriteUsername s/^([^@]+).*/$1/
 <AuthBy SQL>
  DBSource dbi:ODBC:NSAcctDB
  DBUsername xxx
  DBAuth xxx
  AuthSelect  select PASSWORD,REPLYATTR,LoginExpiryDate from SUBSCRIBERS \
                             where USERNAME='%n' and DISABLED = '0' 
  AuthColumnDef 0, User-Password, check
  AuthColumnDef 1, GENERIC, reply
  AddToReplyIfNotExist Service-Type=Framed-User,Framed-Protocol=PPP,Framed-IP-Netmask = 255.255.255.255,Framed-Compression = Van-Jacobson-TCP-IP,Framed-MTU = 1500,Framed-Routing = None,Idle-Timeout = 1800,Session-Timeout = 28800
  AccountingStopsOnly


<snip>

The SUBSCRIBERS table contains a user like this...
username = usertest
password = testing
replyattr = Idle-Timeout=28800,Framed-IP-Address = "203.56.xxx.xx"
disabled = 0

However, the auth-response I get back is...

Attributes:
 Framed-IP-Address = 203.56.xxx.xx
 Idle-Timeout = 28800
 Framed-Protocol = PPP
 Framed-IP-Netmask = 255.255.255.255
 Framed-Compression = Van-Jacobson-TCP-IP
 Framed-MTU = 1500
 Framed-Routing = None
 Idle-Timeout = 1800
 Session-Timeout = 28800


Notice the Framed-Ip-Address is set as expected along with the Idle-Timeout of 123 in the first two lines, however the Idle-Timeout is then reset in the second last line (as per the addtoreplyifnotexist clause)

I am certain this did not happen before as we have been running this config for ages without customer problems - as soon as we upgraded the fault calls began.

Am I doing something wrong or did I find a bug?
