Authentication Failed: ERROR! kDestroy does not exist

[milosg]

I am using NoMachine Small Business Server 5.2.11 on my Ubuntu. After updating to current (latest) version, I can’t edit any settings for my NoMachine server, because I get “Authentication Failed error, please try again”. Before the update, I was able to make changes with my user. Restarting machine, reinstallation doesn’t help. Any suggestion how to resolve this issue?

Or if you now how to set Auto-Lock screen on a server when connecting in a different than UI way, that would be enough for me.

 

My dump from nxerror.log

Hello milosg,

We need logs from your NoMachine server machine. Please, use these instructions:
https://www.nomachine.com/DT07M00098, and send them to forum[at]nomachine[dot]com.

Excerpts which were provided by you suggest that NoMachine fails to start nxnode process, because it can’t validate user. If you use some specific technology for user management, like LDAP or Active Directory, it’s possible that you need to adjust ‘/etc/nsswitch.conf’ file to include alternative sources of user information.
