Failover/redundant passthru servers

Hi, I’m looking for how to configure redundant (failover) passthru connections in the Notes client.

I have clustered mail severs, accessible behind clustered passthru servers, i.e. the following configuration:

MAIL-SRV1 ------- PASSTHRU-SVR1 ----\

\ / ----Notes client

/ \ /

MAIL-SRV2 ------ PASSTHRU-SVR2—/

I would like the Notes client to be able to fail over between the different passthru servers, but I cannot see how to configure this. I’ve tried the following:

  • I cannot use the PT cluster name as passthru server, because the client doesn’t find the cluster
  • I cannot create two connection docs for each backend server (via PT-SRV1 and PT-SRV2) because the client doesn’t seem to use more than one connection doc for each destination server.
  • According to the documentation, it seems that you cannot use a server-group as the pass-thru server.
  • Hunt groups only seem to be for dial-up.
    Of course, in all the above tests, I have created LAN connection docs to each PT server, so the client can connect to these PT servers.

Notes/Domino seems to support cluster failover in all other cases (DB access, routing, replication). However, is there no way to support cluster failover for client PT?

Thanks a lot for any suggestions.
