Joost made a suggestion earlier to add support for a backup LDAP server in order to get high availability. I think it would be a very good feature to have the 'host' specification in the <AuthBy LDAP> clause to accept a string like the ldapsdk call ldapopen(). It would look much like:
<AuthBy LDAP>
Would that be difficult to add ?

Hi Ingvar,

thanks for reporting this. In the forthcoming new release of Radiator AuthLDAP
and other similar authenticators will IGNORE if there is a problem contacting
the database, so you will be able to distinguish between "database failure" and
"no such user" fall through to a fallback database if need be.

The new release will be out in a few days.

Hope that helps.
