Okay, following your instructions I can now connect using sftp but I can
not access the content of the share:

$ ls -dl /srv/sftp/9p
drwx------ 8 root root ... /srv/sftp/9p
$ sftp sftp9p
Connected to sftp9p.
sftp> ls
remote readdir("/"): Permission denied
sftp> quit


I don't understand how I can have both working together.

How do you manage to get it working?
