only local users

[aburger]

it seems, as x11docker is not able to use directory-accounts:

x11docker ERROR: Could not find user 'aburger' in /etc/passwd.

is there a solution for this beside to create a local user?

This is because there is no recent release of x11docker. This is fixed in master, but the README tells you to install like so: curl -fsSL https://raw.githubusercontent.com/mviereck/x11docker/master/x11docker | sudo bash -s -- --update, which downloads from master, but then "updates" to the latest stable version (which doesn't have the fix).
Install x11docker with the --update-master flag instead:
curl -fsSL https://raw.githubusercontent.com/mviereck/x11docker/master/x11docker | sudo bash -s -- --update-master
