CIFS/LDAPS

Hello

I have a A200 with ONTAP 9.3 and I need to add it to AD which uses LDAPS. I have enabled the Use start_tls for AD LDAP connection: true and we also imported the certificate. But the CIFS setup process fails

Error: Machine account creation procedure failed

Error: command failed: Failed to create the Active Directory machine account "FILE99". Reason: LDAP Error: Cannot establish a connection to the server.

What could be wrong? The time is in sync.

Thank you
