In NoMachine v4, release notes :
The NX protocol supports both password and key based authentication methods. Support for Kerberos and smartcard authentication will be coming soon. Once implemented, key-based authentication for the NX protocol will mirror the SSH implementation meaning that you can insert the key for NX protocol just as you do with SSH.
It was in 2013.
Is there plans for smart card support with NX protocol ? We don’t want to use sshd, because it allows users to have other usage. Is there a solution with NX protocol (example : smart card sharing ?)..
