(RADIATOR) ldap <AuthBy ROUNDROBIN>,

[Peter Havekes]

Wouldn't that be a nice feature for a future release? 
 AuthByPolicy roundrobin - witch uses a random one of the <authby > clauses in the <authby group> and only tries another one if there was no response.

Hello Peter -

Thanks for your mail.

What you describe is not possible in a single instance of Radiator,  
however it is very simple to do with multiple instances of Radiator.

You would have a "front-end" instance of Radiator with an AuthBy  
ROUNDROBIN clause proxying to three "back-end" instances of Radiator  
each with a single AuthBy LDAP2 clause.

This approach has the added advantage of providing some parallel  
processing of simultaneous requests.

I often use this sort of design in my consulting practice.

hope that helps

regards

Hugh
