A user can't connect any more to the server

Hello everybody

I got a problem with a user account.

First, we give to him a computer owned by somebody else before, and the client notes was already configured for this other person, I never can reconfigured correctly it and user used the webmail notes successfully until now.

Then we upgrade from Domino 7 to Domino 8.5.1.

Now I remove and reinstall the client for the user, but when I enter the password (during configuration), lotus tells “Server Error: The certificate table does not contain enough valid certificates to verify the public key of its owner”

I found someone had the same problem with lotus 7 here http://www-10.lotus.com/ldd/nd6forum.nsf/869c7412fe5d56b7852569fa007826e3/f0ca62ab2aaa6a30852574250060bd2f?OpenDocument

But I don’t understand the solution.

I don’t have to create cross certificates for others.

Can somebody help me, please?

Thank

IvyAlice
