Just been settings up our Ironport c100 and noticed that per listener you can only have one LDAP lookup host (or many in failover) however what we require is the following:
Inbound e-mail for [email protected] c100 lookups AD (LDAP) of domainA.com for the user and accepts or denies, now at the same time another inbound e-mail comes in but for [email protected] this needs to the do the lookup against the domainB.com AD server which is a completly different host to domainA.com (infact different network/customer).
From what i can see at the moment I would need to setup a separate Listener for each domain with 2 IPs each which would soon get very out of hand.
Has anybody done this before or have any idea how this could be done??
Just a side note I setup an ADAM server and used the AD to ADAM syncronizer to get a copy of the domain into a partition in the ADAM server and then another domain into its own partition but seeing as the C100 needs a base DN this makes this impossible, unless anybody again has some ideas about this....
