i can't create a password for a second user because every time when i mark a user and push the "Password" button, than i get this error: "change password failed: user "MYUSERNAME" does not exist (500)
1. Linux PAM needs the user to have been created in the Linux file System before adding to the PVE GUI.
Created a linux user with useradd survive (not adduser). Then entered the details in the PVE GUI as Linux PAM.
2. PVE Auth Server creates the user with the password as a virtual user in the PVE GUI outside of the linux file system.
