i have configured LDAP Queries with Multiple-host-options: "Laod-balance". 2 LDAP hosts are defined in this querie

Can anyone tell me what happens if the defined LDAP hosts are not available?

Are users cached by Ironport appliance or is there always a new querie for every recipient?

It will keep going between the two. If you want it to use a primary unless it is unavailable, you would pick failover.

As for if both are unavailable, there is a configuration option on the listener that allows you to accept if ldap is unavailable. You will see your work queues grow until the ldap returns.

The ldap is cached if they are already in the list it knows about. You can setup information on how many entries to cache and for how long. Under ldapconfig->edit->pick the ldap server configuration->server->cache.
