    Hi all,

    I am trying connecting between my pcs but I get the next error:

    Authentication error, try again. By joining the domain, do not forget to specify the user name as domain \ user.

    System features:

    • local and remote: 5.1.9
    • local and remote are connecting to physical.
    • local and remote: Linux OS
      • local: Opensuse leap 42.1 and desktop version: GNOME 3.16
      • remote: Ubuntu 15.10 LXDE

    I have fixed ip configured on the server and have found that pings.

    Any help or advice is welcome.

    Thanks in advance.





    Hello EduardoRL,

    Please answer the following questions:

    1. Is it possible to physically log on desktop using the same credentials?

    2. Can you authenticate with the same credentials using any SSH client?

    3. Is host part of AD/LDAP/Kerberos setup?

    4. Are there any authentication errors printed in system logs after failed NoMachine authentication attempt?

    If answer to 2. is yes, the problem is most likely related to PAM configuration. Create backup of ‘/etc/pam.d/nx’ and overwrite it with content of ‘/etc/pam.d/sshd’. Let us know if it helps.
