Signature on the certificate was found to be invalid

Hi,

I have posted this topic before and tried everything they suggested and searched on this topic and tried everything they suggested, but it still gives me an error message.

I am trying to rename an existing user’s common name.

But after renaming, the Admin Requests db shows the error below:

“Error: The signature on the certificate was found to be invalid. Check the log file for

details.”

When I look in the log file, it gives the same error.

I have recertified the user id, the certifier id, checked that all the keys are the same, but it still gives me the error.

Any other ideas?

I thank you in advance.
