Connecting two Domino servers

What would be the steps to connect two domino servers in different domains…

I have a connection document created

I have the other domains .id and have cross certified it

but now i receive an error that states:

Unable to replicate with server XXXX-XXX/XXXXXXX-XXX/US: Your Address Book does not contain any cross certificates capable of authenticating the server.

Where or how do i add the other domains certificate to my address book…

Subject: Connecting two Domino servers

You need to create a cross certificate using the safe id of the other Organization (the cert.id). You can also cross-certify just the servers (cross-certify the safe-id from the server in your addressbook). You’ll need to do this both ways (in both domains)

cheers,
