How to setting permissions by a userId for a dataset

[jpbnetley]

Hi all.
I recently moved over from Truenas Core to Truenas Scale.
I am busy setting up my permissions for accessing my datasets for the apps I install.

For my plex user, I get the userId under apps/edit.

I want to set the permission for this userId under Datasets.
When I go and edit the permission for the dataset, and create a new permission for that userId.

I get the error message “‘2000: user with this name does not exist’”

How do we create permissions based on the userId?

(I tried attaching screenshots, but I get an error stating I can’t attach media to a post)

first create a local user with the id you want and then edit the permissions.

Thank you.
That fixed the issue.
I tried a variant of this, but must have mixed up the ids, or had the ACL on for SAMBA also.

It is now fixed.
Thank you verry much for the quick reply also
