Ubuntu password not working

[talamir]

Hi,

we logged in with ubuntu user until recently and it stopped working (not accepting password).

Reinstalling NoMachine didn’t solve it.  I can get to the server but it keeps rejecting the password.

Latest version of NoMachine on ubuntu 18

Hello

There are a few things to check:

1. In /usr/NX/etc/server.cfg what are the values of keys EnableUserDB and EnablePasswordDB?
Are they commented?

If they are commented or set to 0 it means the NoMachine will use
system authorization to authenticate users. Skip point 2 and go to the point 3.

2. If both this keys are set to 1, NoMachine is using the internal password database
to authenticate users. please use command

# /etc/NX/nxserver --passwd <username>

to set new password and try again.

3. To rule out the simplest mistake, please check if you can use the username/password to login into system.

4. To check for NoMachine authorization problems please run

/usr/NX/bin/nxexec --auth

and use the Username and password used for failed connection. Please provide us
with output.

5. Please check the NoMachine log files for errors/warnings connected with the user login
Files are /usr/NX/var/log/nxserver.log and /usr/NX/var/log/nxerror.log.

6. Please check the system log file – for ubuntu it should be /var/log/auth.log – for any errors connected with failed login.
