MFA caching for PSM SSH Proxy not working

Hello,

I've tried to set up two different PSM SSH Proxy connections with MFA Caching and neither of which succeeded

Environment 1:

The connection through the PSM SSH Proxy works, when the credentials are defined in the PSM SSH Proxy entry. However, if the MFA caching is enabled, the connection crashes.

The authentication mode is set to CyberArk and the credentials are hard coded into the entry:


If I try to connect with this setting, I get two errors:



The SSH Terminal entry should be configured correctly, because it works without MFA Caching.

This is the latest CyberArk version (15.0), so I suspect the issue is caused by some change to the API. The passphrase for the key is not enabled.

Environment 2:

In this case, the CyberArk environment is on version 14.2 and there is enforced MFA with SAML, so the PSM SSH entry is configured for SAML authentication.

When trying to connect through the PSM SSH Proxy, it first asks for SAML authentication, which goes through correctly, but after that I get a prompt for interactive authentication:


I have no idea which password it requests. The host field contains the hostname of the PSM SSH Proxy. In this case, the passphrase for the SSH key is enforced.

Could you confirm whether this is a known issue with the latest CyberArk versions, or whether there's a configuration on the RDM side I might be missing? I'm happy to provide logs, screenshots, or additional details from either environment if that would help with troubleshooting.

Thank you for your time.

Best regards, Daniil
