I seem to have found some problem:
I have a test Openfire server that has a certificate issued by a CA
I import the CA certificate into Spark, Spark says that this certificate already exists:
This is true, next I import the following CA:
and after that I try to connect to the server, but I get this error:
But if I delete the intermediate certificate GeoTrust RSA CA 2018 then I can connect to the server.
Very strange, I imported the complete certificate chain, but I can’t connect!
But if I don’t import the certificate chain then I can connect.
If I do the same in Spark 2.9.3. I import the full CA chain (root + CA), then I can connect, but why does Spark prompt me to add a certificate to the trusted one? I added the entire chain and instructed not to check the expiration date …
