Hello Mathias, hello Greiner.

I know it´s pretty old and I wanted to update the System today to 2023 or 2024. 

I deleted the Objects several times and also the CA. I will not geting an error, it just won´t create new certificates. Even in iManager manually or in eh console by ndsconfig upgrade. The ca an the sas objects are recrated fine.

These are the result of ndsconfig:

Extending schema... Done

Configuring LDAP Server with default SSL CertificateDNS certificate...
INFO: LDAP Server is already associated with SSL CertificateDNS certificate.

Triggering the 'External Reference Check' process... Done

The interessting thing is, that the eDir is working and ldap as well even it has an outdated certificate.

Best Peter

So you've deleted the "SSL CertificateDNS" for the server in question, ran "ndsconfig upgrade" and get the message "INFO: LDAP Server is already associated with SSL CertificateDNS certificate"? Is there a new eDir object for "SSL CertificateDNS"?

yes

And what are the start and end dates if this certificate and of the CA?

And what are the start and end dates if this certificate and of the CA?

2017 to 2027 or with the new one to 2034
