Oh well.
master-master = bad-bad Dont even consider it!!!!!!!!! MySQL's master-master implimentation is completely brain dead and WILL give you corrupt data is a very short time period (It doesn't do ANY locking across the cluster!!!). If you must use Mysql, use Master-Slave replication for as many authorization servers as you wish, but configure only ONE radius server to actually write accounting to the master database and all the others to use radrelay (or radsqlrelay) to get the data to that server Cheers -- Peter Nixon http://www.peternixon.net/ PGP Key: http://www.peternixon.net/public.asc
