Freshly installed NoMachine getting PAM errors

[rubbertoe]

Was wondering if i could get some help.  I installed NoMachine but when i try and remote in using NoMachine i get a desktop where it asks for my login.  I enter my creds and i cant get into my desktop it just kicks me back to login screen. Its just a clean install of the rpm, I haven’t made any changes.  I tried the latest version and this version is 8.13 on RHEL8.10 on GNOME.

Hi, it looks like there’s problem with creating sessions because the home directory doesn’t exist, which looks similar to this bug report: https://kb.nomachine.com/TR04R09659. There is a workaround documented there which you could try. If you send us the logs of the server, preferably reproduced on the latest version, we can check and confirm if it is that known issue or not. You can extract them using the instructions here: https://kb.nomachine.com/DT08U00298. You can attach them here, or send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!
