Hoping to be more helpful here, I know how to implement this functionality
in freeradius, but only when using a mysql database backend (which is a good
idea for most setups using more than about 20 users).
I am assuming you want to control user logins to multiple NASes and this is
what you meant by "user 'x' can only login to IP addr 'y' and /or 'z'". If
you need to just filter traffic based on real network devices, for example
where Y and Z are IP addresses on your network, you can safely ignore my
first radgroupcheck entry below that restricts NAS choice.
If you get a standard mysql setup working, all you need to do is add the
user's password to radcheck (for table names "username,attribute,op,value"
you should have "bobengineer,User-Password,==,nortel"), and add the user to
a group in radgroup (username, group = bobengineer,engineers). then you can
set group-specific policies by putting entries in radgroupcheck and
radgroupreply, such as...:
radgroupcheck: [groupname,attribute,op,value]
engineers,NAS-IP-Address,==,11.22.33.44 (all engineers connecting must do
so from NAS with IP addrss 11.22.33.44)
engineers, Pool-Name,==,engineers_pool (all engineers connecting will be
assigned an IP from the 'engineers' IP pool, which means you can firewall
them off using IPTables (or the Shorewall frontend to iptables, which I
recommend using) or something similar)
Basically this provides you with both tools you will need - the ability to
restrict where users can log into, and the ability to restrict what IP
address users recieve. You'll need to set up rlm_ippool to automatically
assign IPs, and you'll want to make sure your NAS devices send accounting
packets (accounting start/stop are important - also if accounting stop's
aren't sent, you'll run out of IP addresses).
Hope this is a little more helpful than the usually flippent replies on the
mailing list, I was in the same boat before too :-)
thanks,
