Error: Cannot authenticate to the requested node

[Peter Sun]

Test CentOS 7.9 today, NoMachine terminal edition 6.15.1 works on it.

Yes RHEL/Centos 7 works fine as does older version of Fedora. I know it doesn’t work with Fedora 33 & does work with Fedora 25 but that’s as far as I gone.

I’ve sent my log but I am not sure if you received the files, so I try to attach them again.

Attachments:

1. connection.txt
2. session.txt

Hi Peter,

We did not receive your logs via email.

We will need different logs. Can you please collect the logs as explain here https://knowledgebase.nomachine.com/DT11R00181#1.1  and send them via email to forum[at]nomachine[dot]com? Please make sure to add the title of the topic in the email subject. Thanks!

An update on this, we’re moving from NIS to LDAP authentication on Linux PC’s & I’ve found on a Fedora 34 system that has been joined to our Windows domain, NoMachine also is unable to authenticate.

It’s a different error message this time:

nxserver.log

I can log in successfully on this PC either graphically on the console or via ssh.

Hi @Peter Sun and @jkissane,

A Trouble Report has been opened Authentication fails in NIS environment on Fedora 33, RHEL 8 and CentOS 8  and the patch fixing this issue will be included in the next software update.

You can monitor our software update announcements here https://knowledgebase.nomachine.com/software-updates. This thread will eventually be closed.

Thank you very much for the update.

I checked this morning & this is working on Fedora 33 now using version 7.7.4.

Thanks for the fix.
