Cross-certificate server with another server in another domain - HELP

Hello,I don’t manage to cross-certificate a server with another server in another domain. I can just cross-certificate certifier ID with another server or another certifier ID but not server with another server.

Do you know how I can do that ?

HELP PLEASE

Do you have a copy of the other guy’s Safe.id ?If so, when you click cross-certify in your Administrator client, you will be asked to choose a certifier ID. Specify your server’s id (not an O or OU certifier.) Then after choosing the other domain’s safe.id look at the choices in the Subject Name, where you will see the other server’s server-name, org-name, and possibly an ou-name. You can decide to cross-certify at any of these levels, including server/server.
