I have two domains. One domain, lets call it Domain A, is where all the internal users are located and registered. On our DMZ domain we replicate the mailboxes for external users.
These two domains have different admin4 and names databases. Now I want to send adminP requests over to the DMZ domain so that the mailboxes will be deleted when a user is removed.
I have investigated and found that the admin4.nsf has to be the same on both domains, and a cross-domain document has to be created.
I have also heard that replacing a admin4 database in a server domain could be tricky and a bit risky.
What is the best practise for this when it contains about 5 servers, and not much adminP requests at all in the admin4 database.
This must be unique to each domain. You cannot do this across two notes domains. You must have an outbound and inbound Cross Domain AdminP Request document for the domains, if you want the changes to go both ways.
If you only want Domain A to send to Domain B, then first cross certify the O level Certifiers for each. If these are the same O then you do not need to cross certify as they are the same entity.
Then in Admin4.nsf on Domain A, create an outbound to Domain B specifying the Admin server of Domain A as the entity authorized to send requests.
On Domain B, create an inbound Cross Domain AdminP document specifying the Domain A server for the inbound.
