[SOLVED] Add User to access GUI

"Add User to access GUI"

Do not use "Linux PAM standard auth" for this! A pam-user can access the host via ssh. You are asking for GUI access (only?).

Add the new user via Realm =" PVE authentication server", then the user can login via the webgui on all nodes in the cluster.

Yes, only for the GUI. I don’t use SSH. Anyway, I managed to do it. I had to create a group, add the new user to it, and then assign all the resources to the group to administer them. Thank you for the explanation.
