To verify that the CN value is the DNS name of the directory, run the following test.
- Resolve the value in the CN attribute with the name service on the Teradata Vantage node, and Unity server, if used, by running the following commands:
dig tcp -t A directory_DNS_name
The commands return the IP address associated with the directory DNS name.
- Use the IP address to connect to the directory server indicated by the directory_DNS_name. If the IP address does not connect to the correct directory server, the certificate is unusable.
