Help -Signature on certificate problem

Hi Any suggestions for this problem would be much appreciated - I am completly stumped. We have an office in Finland and have just upgraded all clients remotely from 5.11 to 6.5 After this one user got a problem -she was getting the message that her ID had expired (although she had previously had no warnings) So I recertified her as normal, she then got a new message - “the signature on the certificate was found to be invalid, check log file for details”

I have now done the following - created the user from scratch - same problem. Suspected the Finnish certifier - got a backup copy, created new id again, same problem. Replaced the server pubic key in address book with one from backup. Used a different admin client in case it was my client. Deleted the certlog on the finnish server and replicated new on. Nothing has made any difference.

Has any one got any suggestions?

Many thanks, Anne

I recertified the certifier with the next level certifier and its Ok
