use realms to access different mysql tables

[Alexander Papenburg]

Hi Freeradius-Mailing-List,

does anyone of you differentiate sql database table with realms?
E.g.:

Auth-Requests for user1 at realm1 will be checked against table db_radius1
Auth-Requests for user1 at realm2 will be checked against table db_radius2
.....and so on.

I already found out that it is possible to use multiple sql instances,
but for what i understand is that they would be asked/checked one after 
another. That would be nice for failover scenarios but if there are 
about 20-30 realms to check it would be result in a very slow 
performance (depending on mysql host speed).
So is there a better way to solve this Problem? All users in one 
database is at the time unfortunately no option...


Thanks in advance

Alex
