I investigated further and if I chown 101001.101001 autossh in the NFS mounted directtory in the host, everything works for that particular user.
But I cannot e.g. # adduser foo Adding user `foo' ... Adding new group `foo' (1002) ... Adding new user `foo' (1002) with group `foo' ... Creating home directory `/home/foo' ... Stopped: chown 1002:1002 /home/foo: Operation not permitted in the container... I already changed the NFS share subtree ownership to the mapped one (42000 in my case) and asked to disable subtree check from the share (not yet done). This must be something with the difference of normal directory and NFS but what...?
