Issue in setting User auth factories in ClientSession

Hello,

I am trying to setup a SSH configuration with Jumphost.
I am configuring my Jumphost userAuth in the Client . my jumphost can accept both password or private key authorization . so I am setting my client.setUserAuthFactories to accept both Public key and password.

And my SSH host will only accept password. so I was planning to set userAuthFactories in Session for the host.
**session.setUserAuthFactories(Collections.singletonList(UserAuthPasswordFactory.INSTANCE));**

But while executing i can see that authentication mechanisms is always set to the client inputs, the session inputs are not honored.

Can you please let me know if anything is missing in my code or understanding.

org.apache.sshd.client.SshClient client = org.apache.sshd.client.SshClient.setUpDefaultClient(); client.setForwardingFilter(AcceptAllForwardingFilter.INSTANCE);
client.start();

client.setKeyIdentityProvider(
sessionContext -> Collections.singleton(------Jump Host Keypair -----));
client.setPasswordIdentityProvider(sessionContext -> Collections.singleton(---jump host password----));

**client.setUserAuthFactories(Collections.unmodifiableList(
Arrays.asList(UserAuthPublicKeyFactory.INSTANCE, UserAuthPasswordFactory.INSTANCE)));**

ClientSession session = client.connect(SSH_HOST_REFERENCE_NAME).verify(SERVER_ALIVE_INTERVAL).getSession(); **session.setUserAuthFactories(Collections.singletonList(UserAuthPasswordFactory.INSTANCE));**
session.setPasswordIdentityProvider(sessionContext -> Collections.singleton("default"));

Start by tracing ClientSession.setUserAuthFactories into ClientUserAuthService, using the two authentication log excerpts as the reproduction signal. Check how client- and session-level factories are selected during tryNext; done means a session configured with only UserAuthPasswordFactory uses password authentication instead of the client list.
