nas-port always the same

[John Kougoulos]

Hello all,

I'm trying to integrate a Cisco wireless controller in web authentication 
mode with freeradius which uses rlm_dbm as user database. I run also some 
extra scripts using rlm_exec to update the session-timeout etc.

The odd thing is that this device sends as nas-port always the number 1.

So, this breaks rlm_radutmp and the check simultaneous users 
functionality. Obviously the correct method is to try to convince cisco to 
send different nas-port number for every request.

However, in the mean time I thought of changing the nas-port with a number 
based on the calling-station-id (the last 4 bytes of the client's 
mac-address).

  To do this I tried the rlm_perl, in preacct, but as far as I've 
understood from the archives of the mailing list, I cannot change the 
request pairs, at least up to Freeradius 1.1.7. Is this correct?


Is this functionality supported on 2.0.0pre2 ?

Am I in the correct path for resolving this issue or should I consider an 
alternative method?

thanks,
John
