Unable to connect to domino with clients with an existing administrator

Hello everybody,

I got a problem to migrate from domino 7 to domino 8.5.

During configuration (just after installation), the wizard allow to take back an existing administrator.

I wanted to have the notes admin from the domino 7, so i put his admin.id on the new server, and I choose it with the wizard.

The configuration was successful, but when i try to connect (with a standard client or the client administrator)I got this error message :

“The certificate table does not contain enough valid certificates to verify the public key of its owner”

I saw somebody on this forum had the same problem and resolve it with cross certificates, but i can’t manage certificates if the client administrator can’t connect to the server.

What can i do now ?

Thank you for you replies,

Best wishes,

Ivy

PS: I tried install my server with a new created admin. that’s was OK.
