I’ve now manually created a user (tgale) to match my user on my other node. I created it with the UID 1180 to match the UID on the other node and they both have group id 1180 as well (which i checked with id -g tgale). I’m still getting the same error though. How would I make sure the users are the same on the system level (in the passed and shadow and group files). Is there a way to just duplicate the user on the other desktop (I’m running slurm across two desktop computers for testing).
