Error connecting to server: The Server's certificate has expired

I have two Domino servers (6.5) running on an iSeries (V5R2): a primary server for Domino and a Sametime server. The Sametime server won’t start saying “Error connecting to server (primary): The server’s certificate has expired”. I have recertified the server.id file for the Sametime server and put it in that server’s data directory, but the same error occurs. It’s telling me that the Sametime server can’t access the Domino Directory of the primary server, which it must do to operate.

What is this message telling me? How do I get my Sametime server certified so that the primary will let it work?

Thanks for any help.

Have you checked the certification log database on both server to know whether or not the (cross-)certificate is well present into?
