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

Dear Admin experts,

While doing a simple recertify of a Notes user in the DD that is about to expire, AdminP reports the error:

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

We have tried copying the public key from the OU certifier id into the Domino Directory incase of corruption etc, but to no avail. We compared the keys and they are the same anyway.

Any ideas?

Try this:

get a good working copy of the cert ID file from the backup

then Re-certify the OU with the parent O
