Just to clarify: The unknown owner and group accounts in the getfacl
output above are almost certainly the fake SIDs created by Samba to
generate an unambiguous Unix UID/GID to Windows SID mapping. This
occurs if you don't use winbind on the Samba side to generate a real
UID/GID to SID mapping.
The fake SIDs created by Samba are of the form
You can add them to your /etc/passwd and /etc/group files by using the
`mkpasswd/mkgroup -U option, see
$ mkpasswd -o 20000 -U root,corinna -L my_samba_server
$ mkgroup -o 20000 -U root,vinschen -L calimero
This gives a useful output in ls, getfacl or stat.
